Not quite 60 years of freehand sharpening here. I have never owned a diamond surface sharpener.
I have a box of different stones and I use mineral oil with most of them. Everything from scalpels and razors to large double bit axes.
I never let an edge get too far from perfect so I can usually bring them back with minimal effort.

Yup. I almost never use a diamond stone on my own knives unless they come with a really bad edge geometry and need to be reworked right up front.

The issue is that people know I sharpen knives and some of the ones they give me to sharpen are in really sad shape.

I got one awhile back where someone had sharpened it very vigorously and preferentially in the center of the blade which gave it a "reverse belly". Since it was a kitchen knife, it was nearly useless because when you held the edge on the cutting board, the middle of the blade wasn't touching. It touched near the tip and the bolster, but in the middle it was off the board. On top of that, it had an integral bolster that came down to the edge and all of that had to be reworked as well. I ended up taking a LOT of metal off that knife to make it usable again--when that happens, it's nice to have something that can really aggressively remove metal.
 
I have a few very wear resistant steels that you almost must have diamond stones for. S110V, Maxamet, S90V, K390, etc. If you haven’t worked with these steels you can’t imagine… Taking S110V from ~18 degrees to ~16 degrees was a serious chore, and that was with diamond stones.

If you’re just doing a micro bevel touch up then ceramic is fine, but changing the geometry on these steels is a whole other ball game. It’s one of the reasons I prefer more balanced steels like S30V/S35VN/S45VN, SPY27, CTS XHP, VG10, BD1N, LC200N, 20CV/M390 and most recently, Magnacut. I will gladly sacrifice some edge retention to make sharpening more enjoyable, to an extent.
 
I’m also going to start trying my hand at freehand sharpening in earnest
The trick to any sharpening is understanding what is going on gor not going on) at the edge. Most of the difficulties are caused by faulty assumptions.

So, buy a loupe of at least 6x, but I suggest 10x; a plastic cheapy is fine. The ability to see what you're accomplishing on the bevel vs what you thought you were accomplishing will change everything.

After you understand what is going on at the bevel, then you'll be in a position to know if you need different abrasives.

This was one of my big challenges getting back into knives and sharpening recently: learning about different steels.

I have a loupe as well. Doing LC200N on a Wicked Edge 130 is quick and easy whereas S110V took a lot of time. Both were factory edges at around 18 degrees and I took both to around 16 degrees. Chewing through steel on the shoulders takes a lot more time, requires starting with a lower grit, and deburring S110V also takes more time than a more balanced steel.

LC200N on ceramic is still quick and easy but S110V is… a much bigger challenge. It’s just ridiculously more wear resistant.

Give me a sharp knife and a whetstone or sharpening steel and I'll have that knife butter knife dull before you can say Supercalifragilisticexpialidocious......... They invented electric sharpeners for people like me.........
 
I learned how to free hand sharpen a knife on the deck of the USS Mobile in 1972. The knife was a Buck 110 and the stone was the Arkansas that came in a Buck sharpening kit. Both purchased from the ship's exchange.

I can do it, but I've gotten lazier and lazier as the years have gone by. Now I am a big fan of the Ken Onion worksharp.

But I get the zen of free hand sharpening. Enjoy sir and do carry on.
 
I prefer diamond for everything at this point. My KME and Wicked Edge chew through material FAST. I’ve been free-handing completely dull (so dull I can rake them across my skin with no fear) old kitchen knives today. I won’t switch over to my expensive/super steel knives until I can feel confident in nice even edges and I have a setup that will adequately do the job. It’s not like I’m hurting for options, I just really enjoy sharpening and the tactile feedback of the process.

I don’t really want to use water with any of my non-stainless tool steels though.
I Really Don't Think water will hurt anything as long as you Dry and wipe them Down. If They are Food Knives and carbon steel Any food type Cooking oil will help prevent rust and not contaminate them. I have been Using a Beeswax Based Leather protectant and I find that it works well on leather handles and sheaths as well as the blades.
 
My first dmt stone was a blue 6" bench stone. It was a display at ace hardware. I got it wen they closed. It was well used then. I used t another ten years and it finally started cutting slow so I sold it on eBay as wornout.

If a knife is real dull I file it before stoning. Course you got to have fine touch to not damage it. But for reshaping the grind or taking a large knick out, or with being dull to the point of bluntness, filing is the fastest way to get back.

A file is too coarse unless you're doing gross reshaping of the shape. Abrasive papers give you much greater control and you're less likely to leave horrible scarring on the blade. They can be just as fast too. We always used a file on the mower blade, but once I showed my father what abrasive papers wrapped around that file would do he never touched a file to the mower except to knock down high standing nicks. A file is for shaping, not sharpening.

Yup. I agree.

I have used files on blades that are in really bad shape, but the file must be a very fine cut and the blade needs to be relatively soft steel. If the file is coarse, it's just going to make a mess. You may find you spend more time cleaning up the blade after you file it than you would have just doing the work with an aggressive stone in the first place. If the blade steel is too hard, the file won't do anything and you can actually dull the file.

There are better options for reshaping--here's a good alternative. They are actually abrasive stones that are shaped like, and can be used like metal files.

Good Options For Sure.
 
Couple of picks of my stones. It came out of an old packing plant, and the trough was broken. I glued it together and have ordered new stones as needed. I use 3 in 1 oil on the stones. Originally, the trough held oil to rotate the stones through, but I just apply as needed.

That's really important. Keeping a constant angle while you're sharpening is going to give the best results. Imagine trying to maintain a constant angle on a stone that's not flat. You have to constantly vary the knife angle with respect to level to compensate for the valley in the stone. I can't do it, I've tried. I can get a knife usably sharp on a stone that has a valley worn in it, but I can't get it to the level of sharpness I expect from even just a quick sharpening.
 
The duo-sharp diamond DMT stones seem attractive. You can get a base and extra coarse/coarse and fine/extra fine for about $140. They say they can be used wet or dry. Any thoughts from you folks who free hand regularly? If I should spend more on something else I would rather do so. I have plenty of sharpening options already so I’m in no particular hurry.

Big reason that I use Diamond Sharpeners.
 
This magnifying glass is the most important tool I have to ensure that the blade comes out sharp.

If you cannot see what you are doing to the edge, you will never achieve a truly sharp knife. You will see if you are not holding a constant angle on the edge. Ideally, you want one flat angle to each side, you do not want to see multiple grind marks, which happens when the angle is varied.

And then, you want to look at the edge, facing you, and see that the bevels are symmetrical and the edge centered. You want even and equal angles on each side of the edge.

I use coarse DMT stones to set the edge bevels, and then finish with a light sweep over the surface of a medium red india stone to break the crest that always develops.

I am proud of my edges, so proud, that I now am wearing a cut glove on my food supporting hand, because I got tired of all the cuts that occurred! One National Match, I spent the whole time with big bandages on the thumbs of both hands! I stay at Extended Stays and cook my own food, and I managed to mangle my thumbs wiping the blade of this thing:

Commonly called a "burr". Being able to reliably form and detect a burr is the foundation of freehand sharpening.

Ok, does anyone else sharpen utility/box cutter knives? I just had to break down a number of cardboard boxes and the blade got dull. A few passes on the stone I keep in the garage got it cutting again. They are super-easy to sharpen because they're so thin and because they're already set up with a good edge geometry. You don't need to take much metal off to get a great result.

I'm not really advocating sharpening those blades--the point of having removable blades is that you can swap them out in a hurry when they get dull. The thing is, I can find that sharpening stone faster than I can find my spare blades and I can put an edge back on the blade that's already in the knife about as fast as I can put in a new blade. :D
 
@SteadyD -- I've been a member over at Bladeforums for a while, but never really did much there. That said, as I've become more interested in sharpening, I've spent a little more time there. I asked a few questions and was directed to a couple of videos. They may be too basic for you, but I found this one particularly helpful.

I strop them as I go, but I know where my replacements are (somewhere in the 13th layer below the surface of the pile of stuff on the bench). ;)
