My grandpa would stone knives razor sharp his CASE XX still has an edge. I've been practicing with cheap knives no way will try my CRKT and BOKER
 
Sure, but what's next - the lost art of putting your own socks? That "Japanese art" of sharpening knives WAS the only way to do it as little as some 20 years ago. He was "thinking about investing in a whetstone". For weeks. For weeks... Life changing decision, I can bet! I'm sorry for being so sarcastic, but this incapable-of-doing-simple-tasks human is a disgrace to mankind, not a trend-maker.
 
Pretty much the very second I got into woodworking, I learned of Japanese waterstones. There are other ways to do it just like sharpening a knife but using old school stones is the first thing that is covered and at one time or another any and all hand tool woodworkers use stones. I still use mine but I compliment them with a Tormek.

Also traditional sharpening is used in the straight razor world as well very often. When I first delved into straight razor sharpening the very first instruction was manual sharpening using waterstones. The guy in the video mentioned he had purchased the waterstones from Lee Valley. A woodworking supply house among a few other things.
 
With today's hard steels I have to use a diamond stone to set the bevel. Then I use a medium or fine india stone to remove the burrs

But the most important tool, is a magnifying glass. The one on my Swiss Army knife works just great.

With the magnifying glass I can see just what I am doing to the bevel and the edge. Without the magnifying glass, I am clueless. Seeing what I am doing allows me to get the muscle memory to keep the same edge to stone angle, and to stop removing material once the edge becomes unsymmetrical. Then I center the edge by restoring symmetry by removing material from the other side of the blade. If you can monitor a process, you can control the process.

And I have lots of cuts on my fingers, attesting to how sharp my knives are!

I probably have 200+ stones in my shop. Japanese water stones, carborundum, India, Washita, Arkansas, ceramic, diamond, and more that escape me memory. I am currently fond of the ceramic waterstones.

I can't maintain an angle worth a flip with traditional stones. I can get it coarsely sharp, but not scary sharp by hand. Lansky guided diamond kit for me. Scary! And taught my son with it, so I'm encouraging the trend...
 
I sort of feel like they guy that wants his kids to learn to drive a manual stick shift in case they ever have to. (shoot my Dad would not let me drive the nice auto trans car until I mastered the old station wagon with "Three on the tree")

fact is most cars and light trucks are automatics these days.

There are a lot of tools that make knife sharpening easier for the never got the hang of a manual transmission crowd and there is not a thing wrong with them....except most are leave at home or in the truck things. Not near as handy as a file in the hip pocket and a pocket stone in the front left.

On the other hand most folks today did not have a butcher for a Grand dad that insisted they not use anything but the bench stone for sharpening the shop knives.

When my best bud, who after a couple of years of my teaching still could not sharpen a knife, went out and bought one of those things that clips onto your buck knife to keep the angle right, I was appalled! Guy had an IQ of 140 + but could not hold a knife against a stone and drag it at a decent angle! Imagine my shock when I found out MOST guys in my Infantry outfit did more damage to a knife than sharpening it when they applied steel to stone!

Fact is that knife sharpening which some of us have done with and old brick, a concrete curb, the bottom of a ceramic coffee cup ect. ect. actually is something of an art form.

Finding the right "crutch" can be an expensive outing, though folks sharing on here can be helpful. Me I do not run worth a flip and never had yet I know folks that do 10k fun runs for fun. I can sort of waltz and fake a two step but any other ballroom dancing is beyound me. Juggle? I don't think so. Why would I poke fun at someone that can not sharpen a knife?

Find what works best for you and use it. Don't worry about critics or fashion, just....get'er done!

Touched up the edge of a folder on the hotel counter top this weekend and stropped it on the back of a belt. I agree that it is an art form and I think that it is great that lost arts like sharpening are of interest to more people today than a few years ago.
 
I recently tried my hand at sharpening again. It's my first try with a waterstone. Before that, I'd always used an Arkansas stone. (Go figure.) In any event, it was kind of rewarding to put an edge back on a knife that had needed it for a long time.
 
I have been sharpening my own knives, axes, and saws since I was 11. Learned in the Boy Scouts. Not sure why it's seen as such a difficult skill? We humans have been sharpening bit of metal into cutting edges since the bronze age.

Maintaining the bevel isn't as simple to the novice as it is to the experienced person.

I had to show an electrician in his early 30s how to use his grandfather's novaculite stone. He thought it was some sort of strange ceramic. While he'd seen his grandfather sharpen with the stone his grandfather never taught him how to sharpen. It fell to me one morning when I was visiting their morning meeting. This guy is good with his hands, smart enough to make Journeyman at a DOE site, but he knew nothing about bevel, angle, steel, etc. Once I explained what the bevel angles meant and showed him how to use two hands to find and keep the angle he became much more consistent in holding the angle to get the edge. It didn't take long, but it was information that grandpa hadn't shared with him so it was lost until then.
 
The other issue with sharpening difficulty is having some kind of metric to be able to assess the results before the process is completed.

Before I understood about burrs and how to detect them, my results were very inconsistent. I would spend a lot of time sharpening and when the whole process was complete, the knife wouldn't always be sharp. I'd have to start the process all over again without understanding what went wrong or what I should do differently the next time around.

After learning about burrs, I could very accurately tell at each stage when that stage was complete before proceeding to the next step. And when I was done, the knife was ALWAYS at least shaving sharp.
 
I was looking for some videos I saw earlier in the year where people were making very, very sharp knives from paper and I came across this video. This guy has a sharp knife:



In the comments of the video they mention surgeons knives with sharpnesses in the nanometers made of diamond and obsidian:

If you want a repeatable method for testing sharpness that provides a numerical output, this company provides such a product.

In the interest of full disclosure, I have not used any of these products personally.

I think sharpening is becoming trendy along with polishing the edge. On the blade forums sharpening by hand seems to be what most do. The two biggest things that contributed to my blade sharpening ability was controlling the angle and burr. These two things give me the sharpest and most durable edge. I admire those that can free hand sharpen on a stone. An ability I can't seem to master. Even as forgiving as chain saw blades are I have to have something to control my sharpening angle. With a chain saw blade the angle makes a difference. As far as polishing the blade (strops, diamond paste, etc.) that may or may not be overkill. I haven't seen the need to go that far. I purchased one of these sharpeners a couple of months ago. It is a very nice sharpener:

The sharpness tests in Sharp Dogs video is what I use. It was taught to me by an old guy here on the forum, RCModel. He also liked using supermarket register tape instead of regular paper. I miss our calls RC, RIP my friend.

Try phone book paper. Or better yet, polymer fishing line. THAT'S a challenge! That knife in the video was cutting relatively thick paper...easy peasy.
 
My test is ripe tomatoes. If it will easily cut a ripe tomato you're good. Have to admit though, I learned to sharpen a knife working as a bus boy in a restaurant where part of my job was stocking the salad bar. Man people can eat a lot of tomatoes …
