If he had six belt sanders with different grit belts, the sharpening time will be cut to one third of so. On the other hand, it's not necessary to have so many steps, two belts and a strop is enough.

I built one the same, and am very happy with it. The bench grinder runs at 1400 rpm (half normal speed), and is mounted backwards so that the belt run away from you. (mine is by Sherwood). The linishing belt is mounted on a multi tool like this one - www.justtools.com.au/multitool-belt-disc-grinding-attachment-50mm-x-915mm-po362. These are available in 50mm wide and 100mm wide. 3M Trizact do fine grit belts.

Interesting why anyone would want a knife blade that sharp, I would have to touch up the blade after every single cut if it was that sharp. The sharper the blade the more delicate the edge surely? Sharpening knife blades to ridiculously scary sharpness seems to be the fashion today when few people really understand anything about knives at all.... as long as they can cut a sheet of paper on camera well how fantastic is that !!
@jimmygrey6848

A properly honed fine edge with the appropriate angle for the intended use, stropped before and after use should last longer than any other type of edge, with proper care and use touch ups shouldn't be an issue. Sharpness doesn't always mean delicateness, the angle, grit size and steel type as well as edge hardness all are huge factors in determining the type of edge a knife should have. The edges I put on my knives are finished at 600 grit at 25 degrees, then stropped with leather and polishing compound (not sure what grit the compound is) And I am willing to put money on it that my edges are sharper than the ones in the video, but they aren't delicate either. The 600 grit leaves micro-serrations which aid in slicing and also seem to last longer, stay sharper. I have chopped piles of wood with a knife made of O1 tool steel with the edge I just outlined, and since it's initial edge, it has never been sharpened. Still shaves better than my razor.

I can almost guarantee that something sharpened to 25* included or per side is not sharper and more durable then that edge. 25* per side is a typical use it in the woods/hunting knife edge. It's durable but not particularly keen. Stropped it can very easily be made to shave hair, but it will not go through lighter paper (phone book, some catalogs...) like that. If that's a 25* included angle (12.5* per side) you'll have a super keen edge but not something with any durability to it at all, with most blade steels you'd likely roll that edge cutting paper or opening packages. Most of the "super steels," stuff like S30v, S35vn... will tolerate down to just around 17*/side, sometimes as low as 15* before you start having problems with them in normal use, and the more typical blade steels like AUS8/AUS8a, the typical import and european stainlesses... will roll easily at 17*, and need either a micro bevel at ~19* or so or a convex edge to keep them from rolling unexpectedly (you can make them work in that range but you have to be careful with how you use them). He's likely getting a 15-18*, slightly convexed bevel with the way he's holding that knife (he's convexing in between grits by using the slack part of the belt then moving forward and putting a flat bevel on it), and kitchen knives don't see the abuse that a pocket or hunting knife does, so it's likely a durable enough edge on it (most kitchen knives tend to use softer steel than a typical pocket/hunting knife which changes up technique some. I suspect this is the deal with him having the mounted steel in front of his grinder, I've had issues with getting a soft wire edge in grinding them that is hard to deal with, it's almost like the metal is gummy). If you're getting a sharper and more durable edge using just 600grit paper and a strop at either version of 25* then you're defying the laws of physics.

Mark Pikas I sharpen all the blades I make at 25 degrees each bevel on 600 grit diamond stones, followed by a strop on the split side of leather with compound. I go 20 degrees for kitchen blades. But they are indeed as sharp if not sharper than this. They slice through the corner of a full phone book with minimal pressure, catalogue paper, tracing paper etc. the thinnest papers I can find all sliced with ease on my 25 degree edges.
@mpikas

Some of that depends on the intended use, bade steel and blade profile. That edge would likely get a little scratched up and not push cut thin paper as well quickly in normal use (though may keep that edge quite long doing something like sushi prep, some meat as long as you don't hit any bone... and his market is high end restaurants), but should retain enough of an edge to shave hair and should be relatively maintainable on a steel. I maintain a similar edge on all my pocket knives, but admittedly I have a strop sitting next to their case and will typically make a few passes over it when I put it in my pocket. In my case most are made of harder steel then most kitchen knives but even lesser blade steels can be maintained at close to this edge in normal daily use without having to do much more than strop them once in a while once you get a good edge on them. Once you get used to having a REALLY sharp knife in your pocket all the time, you really start to appreciate it and have a hard time understanding how people carry what they carry, deal with the factory edges on knives, and how dull most people's kitchen knives are.

Wonderful video! You can tell you did a wonderful job with that edge. You paper test at the end with newspaper... what a difference from most you see hacking through copier paper! Is that belt/ buffer home- made ? Does it use a planetary gear in the drum end ? I see the belt turns quite slow. What is the SFM ? Thanks for the video and your time.
