Interesting, taking the 52100 to that fine an edge, his work took his knife blade where he wanted it to go. You could consider that a success.

He would cry if he saw the way we test blades, and how great the difference is between a fine edge and 320 grit edge.

Not many guys are able to produce an edge capable of passing the HHT. Especially freehand on a knife.  

The video shows an investment in high end abrasives, very thin edge geometry, and very good technique.  

It's definitely a fun achievement, but in my experience Ed's right. That type of edge has a tough time slicing rope or passing the three finger test. It will easily push cut rope, but not for long.

Still, nicely done.  Wink

Years ago one of my clients had purchased a knife, when he got it he decided it was not sharp so he sent it to some Japan maker who sharpened the knife on water stones and charged him a lot of bucks to sharpen his knife. When he got it back he tried to dress out a deer and could not using my knife. 

He sent the knife to me wanting to know what the deal was. I tried to cut some rope with it and it would not make one cut, it would cut paper and shave hair but that was it. I re-sharpened it on a 320 grit stone and sent it back to him right away because he was going to Canada on a special hunt. I suggested that he try the knife using the dull edge like the one that was on the knife when he bought it.

Several weeks later I got a call and an apology, he loved the new edge and ordered more knives. You can get a knife too sharp to use on some materials. You as a maker need to match up the edge you put on your knives with their intended purpose.

Good point and interesting video.  I've played around over the years with different edges and I keep coming back to a 320 grit main stone with a light honing on a fine Arkansas stone.  Not enough to remove the "teeth" from the 320, just a light dressing.
