Let me start by saying that I am by no means an expert, so I invite correction or civil disagreement by those of you who know more about this than I. With that out of the way, in my quest to re-learn how to freehand sharpen a knife, I've made some mistakes. Fortunately, I haven't made any real expensive ones. Yet. Nonetheless, I thought I'd post some of the lessons I've learned for the benefit of any who come along later and want to learn to sharpen knives freehand. Anyone who has gone through the process of learning to sharpen a knife that way is welcome to add to add to this thread.

First of all, let's define the terms. When I say "freehand," I'm talking about sharpening a knife without the benefit of a guided system, like Lansky, Gatco, KME, Edge Pro, Wicked Edge, or Hapstone. If you google any of those, you'll see what I'm talking about. They use some kind of jig or framework to ensure that the bevel is very consistent. Don't misunderstand. They have their place and can be a very useful tool. But freehand is exactly what it sounds like. You hold the knife in your hand, and guide it over a stone until it gets sharp.

So, without further ado, here are the mistakes I made, and lessons I learned, on the Road to Freehand.

1. Don't buy a bunch of butter knives at thrift stores, thinking you're going to put a razor edge on them. Ask me how I know . . . . I went to Goodwill, hoping to find some beat-up knives to sharpen. At the GW here, they don't sell the knives that are fit to sharpen. About 90% of the knives they had were butter knives. I probably could have ground at one for days and come up with an edge, but the reality is that the steel used to make them really isn't suited to sharp edges.

2. As an alternative to butter knives at thrift stores, head to the garage sales. We got some great deals on actual, useful kitchen knives. I scratched up a few blades along the way, but my wife and I ended up with a few very serviceable, and decently sharp kitchen knives at a pretty low cost.

3. Older steels are your friend. You don't have to learn to hand sharpen on the latest, greatest "supersteel." Those steels are pretty fascinating, in a technical sort of sense. But with that said, the new supersteels are very hard, hold an edge a very long time, and can be hard to sharpen. That's not conducive to learning to freehand. A few older knives in high carbon steel can go a long way in boosting your skills. They sharpen pretty easily, which also means you can dull them again (making them suitable for re-sharpening) pretty quickly.

4. You don't need exorbitantly expensive gear. Yes, a good set of diamond plates will serve you well, and put an edge on almost anything. Same thing for a good set of Arkansas stones. In terms of price, the sky is the limit. That said, one of my favorite stones as of this writing is a water stone that cost me less than $30 on Amazon, and I can put a good edge on a knife with it.

5. Learn a little bit about knife steels. I'm no metallurgist, but I think I've benefited from some internet reading on steels. I can feel the difference on the stones between 154CM and S30V. Once I figured out where those fell on the Rockwell Hardness scale, it let me kind of pick out a few other knives (on sale) that were in the range that I enjoy sharpening. I don't know of anyone that is less willing to practice something, if they enjoy it.

6. Know why you're sharpening a given knife. If all you want is a reasonably sharp edge for kitchen work, there's nothing in the world wrong with that. But I have discovered that The Perfect is the Enemy of the Good. By that I mean, I've had at least a half dozen events where a knife was sharp coming off the medium grit stone, but I bungled it on the the fine grit stone and had to start all over. If I just wanted a good working edge, I should have stopped after the medium stone.

7. Buy some Sharpies. Marking the edge with a Sharpie makes a big difference in being able to see what's going on in the bevel of your knife. I use hot pink, as it contrasts with the silver of a blade more than black, but use any color that works for you.

8. Let the stones do the work. When I want to really reset a bevel, my first impulse is to press hard, and get it done quickly. I get much better results with light passes, letting the stones do the work. Patience is key.

Anyone else care to weigh in?
 
All good points.

Get a jeweler’s loupe and watch what is happening at the edge.

You don’t need expensive gear, but don’t skimp either. Some stones won’t work as well as others. I have two double-sided diamond stones that were $60 each. You could get by just fine with the Coarse/Fine stone and never buy anything else though. It will produce shaving sharp edges.

Strops! For either finishing a freshly sharpened edge or maintaining that edge, they are just remarkable. A $15 strop will make a shaving sharp edge VERY sharp. It will often make an edge that isn’t quite shaving into a shaving sharp edge.

I echo staying away from the really crazy steels. I’m doing pretty darn good free hand and I am nowhere close to ready for S90V, S110V, Maxamet, K390, and some others. I really like some of these steels, but I am still saving them for my guided systems.

Good beginner steels that I have personal experience with are the 8CR steels, 9Cr steels, LC200N, and CTS-BD1N.
 
I just started sharpening my knives a couple of years ago. My kitchen knives are modern and very sharp. Just stropping keeps them that way.

Most of my knives are used for my leather work and need to be very sharp. I'm trying to cut 2 thicknesses of 10 ounce leather and want to do it with the first pass of the blade.

I use a couple of head knives and skiving blades. I've learned that a dull knife will cut you faster and worse than a real sharp one.

I started with a diamond stone in medium and start by passing it 10 times on one side, then the other side, 9 times on each, 8 times... well you get the point. By the time I get to the last pass it's pretty well sharp enough to just strop it.

I also have a set of stones that go from course ( 400 ) grit to 1000, 3000, and then 8000 from KERYE. These are water stones. Rough up the blade with 400 grit and then work my way up followed by the strop.

I've even gotten my pen knife to cut 10 ounce leather with little pressure.

I'm sure there are better ways but that's what's working for me at this time.
 
I can add a few points for folks that are looking to buy sharpening equipment.

1.Dished out stones are hard to work with. The more coarse stones tend to wear more quickly. Its a side effect of exposing new grit to cut quickly. The cheaper water stones and man made stones tend to be worse at this though. Plan on investing in some sort of method to flatten your stones eventually. Some people buy 2 water stones in each grit and rub them together. There are also diamond lapping plates, or a large belt sander usually works but is hard on belts.

2. Diamond stones stay flat but wear out faster than other types of stones. The softer the steel you are working with, the harder the diamonds bite into it and the more likely they are to pop out of the bonding material. If you invest in high end diamond stones I would reserve them for higher end, high hardness steels.If you invest in entry level diamond stones, just know that they don't last forever.

3. Ceramic stones stay flat and cut fairly quickly, but have to be cleaned occasionally. Any stone that you use dry will eventually load up with metal filings and have to be scrubbed clean. If you are on a budget and buying just one stone, make it a medium grit of some kind. An ultra fine ceramic (or water stone etc. )stone will take so long to put an edge on something you will get discouraged and quit.

4. You don't have to commit to one type of stone. I have an assortment of stones and use them in different combinations depending on what I am working on. Its not uncommon for me to start with a coarse diamond stone, then go to a 1000 grit water stone, and finish on ceramic stones and then strop.
 
Spats' #9. The Cheapskate's Angle Guide -- Angle guides aren't overly expensive, but you can make one for free. Take a piece of paper & tear off a corner. Fold that corner so that the straight sides meet. That will bisect the 90* corner and give you a 45* angle. Now fold it so that the straight sides meet the fold you just made. That will bisect the 45* angle and give you a 22.5* angle guide that you can set on your stone.
 
I think the angle guide is helpful to learn. When I started with a smiths kit it had a plastic guide.

I find, a soft Arkansas stone best to learn on. Diamond has a different bite to it. You get a better feel for it with Arkansas stones. Least I do.

The knife size makes a lot of difference. A medium sized knife, 3-4” blade is easiest for me. A small knife has a small handle, and a large knife too long a blade. A mora knife, like a companion, is good to work with.

I’ve been reading blade forums about knife sharpening and picking up tips for years. Those folks like their knives like we like our guns. I learned when I was a kid and I’m still learning.

Carborundum stones are the most frustrating stones to use. They have their place but sharpening fine knives is rarely one of them. They are coarse as a brick and the slurry scratches blades. They also take a pint of oil to get wet. You can condition them with Vaseline so they don’t take so much oil. Too many times folks start a kid off with those worthless pocket slip sized carbo stones and all it does is ruin people on freehand sharpening.

A tip I’m still learning, there is no shame in using a pull through ceramic sharpener in a pinch. Example, when you are at a friends house and their kitchen knives are dull, get that pull through and get a working edge in a jiffy is better than getting the stones out and flexing your sharpening powers for everyone.
 
Harder stones are easier to use as finishing stones. Ceramic, diamond, Arkansas stones etc are easy to finish with as they don’t dish, the surfaces don’t create a slurry that can make finishing difficult, and they work with light force. Try bearing down with a ceramic rod and you’ll see a ripple move down the edge in the steel.

Sharpening freehand is much easier if you don’t care what the knife looks like when you’re done. Also it helps to remember rigid angle control isnt necessary, and is in fact not possible when freehand sharpening, particularly when you sharpen with the knife in one hand and the stone in the other.
 
Would something like a Sharpmaker or angled block to hold the stone be considered freehand? I've used wood blocks to hold the stone at the desired angle while keeping the knife horizontal, as opposed to holding the stone horizontal (table or bench top) and angling the knife. The Sharpmaker works similarly except instead of horizontal the knife is held vertically and the stones held at the desired angle.

That would be semi-guided in my opinion. I like the Sharpmaker a lot for quick touch ups.
 
It’s definitely easier than just laying a stone in the table and having at it. One is just changing the angle that is hand held to something that is easy to judge. I have argued both ways before.

If you haven’t tried before, the Sharpmaker triangles work great as a finishing step held like a short steel.
 
I've done that, once. I've had my Sharpmaker so long I used it to change edge bevel angles from 22 to 15. I finished the first one yesterday after buying the knife in 2002. I actually did dish the corners of my first set of brown triangles. Not much, but enough to see, barely.

I use bench stones on a wood block set slightly lower in angle to the desired Sharpmaker angle. I set the bevel on the bench stones, then remove any burr and add the final edge on the Sharpmaker. IMHO, this is where the Sharpmaker, and ceramics in general, shine. These threads have made me want a knife that I both carry and sharpen only with freehand methods. My Delica is my main carry knife, and it has too much work into it to change how I sharpen it now. Any excuse for a new knife I guess. Now to browse.
 
Diamond stones. Sure, many steels can be sharpened on something other than diamond, but diamond works much faster AND will sharpen the steels that can’t be sharpened adequately by anything other than diamond/cbn.

Do your best to deburr on stones. It helps to do edge leading strokes only to deburr and typically can be done on the coarse stone during your sharpening progression. Some steels will continue to form a burr on fine stones, in which case edge leading strokes will minimize or negate the burr.

Strop! And in between sharpenings, strop! I’m going to change my username to Sir Stropsalot.
 
You all have inspired me to practice freehand sharpening more. I had cleaned up the bevels on out main kitchen knife a couple weeks ago and reset them with 220 and 1000 grit stones on a 22 degree wooden block on a base similar to a Sharpmaker. Last night I grabbed my Norton Economy Coarse/Fine combo stone and sharpened it while standing at the sink right after washing it. I do cut into the stone very lightly before sharpening this knife to try to get things back to square one. It takes a lot of abuse at the hands of the children and wife, what with “cutting board” being a synonym for “ceramic plate” around them.

After cutting into the stone, I had a faint shiny line along the edge that reveals nicks and dings. I then shaped the edge with a dozen or so passes on each side. The shiny line was gone as were the flats from nicks and such. If it’s really bad, I repeat this until most of the nicks are gone, but rarely more than three times.

Following shaping there is a usually a small burr. I’m really just trying to get the light reflection to go away but it’s only about 2 passes between no reflection and a burr.

After shaping I make one or two slow passes with LIGHT pressure at about 30 degrees to remove any burr. Then I go back and sharpen at the original angle or slightly more for about 10 passes per side. I was rewarded with an edge that would whittle beard hair so I stopped. Sometimes I use a ceramic rod but it stays in a different drawer than my kitchen so I didn’t want to dig around and go get it.
 
I also have a Byrd (Spyderco) I may dedicate as a free hand sharpen only knife. I need to reset the bevel and probably regrind the whole blade but let’s do one thing at a time.
 
I only freehand sharpen. Splitting axes and mauls with an angle grinder and flat bastard double cut. Chainsaw with round file.

And blades, knives, scissors, etc. with DMT Diamond Whetstones. Keep an eye on auction sites, for sale adds. You can pick up super deals for 10 cents on the dollar during husband die off sales.
 
I've seen a bunch of references to The Razor Edge Book of Sharpening by John Juranitch. I have not been able to find a copy in my local libraries, but it has just come to my attention that it is available as a free download. https://archive.org/details/Knife_Sharpening/mode/2up

I know/knew John. When I was a kid, every 4th of July included watching him shave with an axe in the park. My dad, a machinist, made some tooling for John’s shop.

Shaving with an axe? I'll bet that was quite the sight.
 
Last weekend, My mom gave me my Dad's knife collection. He's still alive, but not in good health. What with my dad having been a surgeon, one would have thought that the knife in his pocket would be sharp. One would have been wrong. This Case Mini Trapper may well have been the last pocket knife he ever carried. The edge was chipped and it was as dull as a brick. It would not cut paper. I doubt I can get my Hapstone to work on a blade this small, at least not without some kind of attachment that I don't have. Besides, this one just begged for freehand sharpening. So it put it on the diamond plates yesterday and then the 400 grit water stone and got a working edge on it. That was all I had time to do before having to go back to work. When I got home, I touched up the edge with medium and fine Arkansas stones. She's right as rain now.

I'm a sucker for a good Trapper pattern knife. I still have my dad's, though it's retired. I used it heavily after I got it and it deserves it's rest. That might be a good model for my free-hand-only knife. I could get one of the large Case yellow trappers in CV+ steel and just sharpen it only free hand.
 
....Strops! For either finishing a freshly sharpened edge or maintaining that edge, they are just remarkable. A $15 strop will make a shaving sharp edge VERY sharp. It will often make an edge that isn’t quite shaving into a shaving sharp edge.....
@SteadyD ... I finally got a strop!

I broke out the stones again to sharpen a coworker’s knife. While I was at it I sharpened my Byrd Tern. It’s a small one hand opening slip joint with a solid half stop and stout back spring, complete with Byrd’s comet shaped opening cutout. This was a work knife for store stocking and it looks rough. I’ve been freehand sharpening it for a few years. I just found it a while ago and decided to grab a coarse/fine combo stone and have at it. I was able to get an edge that would cut a beard hair held between my fingers but it took a couple tries down in the tip. It looks like I used a sidewalk but it’s sharp. My plan is to regrind it when I do my Delica next time.
 
I'm still on this road, I guess, and a little further down it than I was before. I have a Hapstone R2, but most of my sharpening is still done freehand. As I may have mentioned, when I first started down this path, a chef I know suggested a Sharp Pebble 400/1000 grit combination stone. It's described on Amazon as being made of "green silicon carbide," and I've been very happy with it. Once I learned how to use it, I was able to consistently get very "serviceably sharp" edges off of it. Never really razor-sharp, but easily good enough for everything I actually do with a knife. (Which ain't much).

Anyway, I finally reached a point where I felt like I'd hit the end of what that Sharp Pebble could do for me. IOW, I think (I hope) that the quality of my edges is limited more by the stone than by me at this point. So, I headed off down to look for a new, higher-grit stone. I asked for advice over on Bladeforums (where some of those folks have gone much farther down The Sharpening Rabbit Hole than I ever really expect to), and settled on the Shapton Pro 2K. I tried it out last night, and here's what I posted over at BF:

I took her for a spin last night. I got out my Benchmade Sequel (154CM), Native 5 (S30V), Case Mini-Trapper (unknown), and CRKT Offbeat II (8CR13MOV) and sharpened them all. I've been able to get a serviceably sharp edge for quite some time, but I've never been able to get a really razor-sharp edge. I've snitched one of those big desk-mounted magnifiers with a lamp from my Dad, so that I could see what I was doing. (He doesn't use it.) For each knife, I put it on a coarse stone, both to make sure I was starting with a decent edge and to develop a scratch pattern I could see. I did a little reprofiling, as well. (Some was intentional, some not so much . . . )

After that, I went through my Sharp Pebble 400/1000 grit stone, maybe an Arkansas stone (depending on the knife), before moving on to the Shapton. I tried to sharpen the Mini-Trapper on it a little before doing a short lapping with my 600 grit diamond plate, as was suggested earlier in the BF thread. I don't know that I could really tell a difference between before and after lapping. I'm also starting to realize that some lapping using my diamond plates might do my Sharp Pebble stone some good.

Overall, I'm impressed. The finish is much better than I was getting off my Sharp Pebble 1K, and it wasn't hard to get there at all. All knives came away with very sharp edges (for me), and an outstanding polish (again, for me). Given the grit level, I was surprised at how fast I was able to get to the better finish. I could see swarf on the stone from the first pass of each knife. It's not a mirror finish, but it's "well on the clearer side of hazy," for lack of a better description. I may be wrong, but I feel like I could get a true mirror finish, or very close to it, if I spent enough time developing my skills and using this stone.
