Schrade uncle henry 153uh

[realitycheck]

Well today I decided to try something different. I cut some wood so I could freehand on a tilted stone. Well I got the uncle henry out and tried to reprofile it to a 15/20 edge. Man that thing was thick I finally got it really close to where almost the whole edge was reprofiled to 15 so I started on the sharpmaker and kept going with the primary bevel. Then switched to the 20 degree back bevel I went through my routine with the brown/grey stones and it shaved hair very easily. Then I switched to the whites and just did a few strokes and it is actually duller will not shave now. I stopped cause i'm going to finish tomorrow night, but thought it was really weird that it was duller by doing a few strokes on the white stones anyone know why?

Also, I pulled out the benchmade mini grip while I had the white stones out it's time to sharpen it. I havent touched it since I got it so it needs a new edge. I ran a sharpie across the very edge of it, then did like 4 strokes on each side of the white stones. Boom its shaving sharp again. I love this knife and my sharpmaker. So since I ran it across the 20 degree angle setting and cut across the edge of the knife, that means the factory edge is more obtuse than 20 degrees right?? thanks for the help guys

I've dulled edges when stepping up the stones because I have shaky hands, and will sometimes run it across at a funny angle and kill the edge. I tend not to use the edges on the white stones, just use the flats, and that seems to prevent it.

If you ran it through at 20 degrees and hit the edge, that means you're more obtuse than the factory. If the factory edge was more obtuse, you'd be up on the shoulder of the edge.

Well I was using the flats on the whites. Hmm, maybe I did turn it a bit of something. I did change the pressure too I used less pressure on the whites. I dont know we'll see tomorrow.

So the mini grip must have like a 17 degree angle from the factory. Somewhere around that number?

Well I started back at it tonight. Went through the white/fine stones and the knife was sharper than ever. It push cut through very thin paper, very easily. The hair on my arm just popped off. So I thought well lets see how sharp I can get it. So I went through the ultra-fine stones. Well when I got through it was still shaving sharp and pushed through the same thin paper. Just didnt seem to be as easy as before, and the hair didnt pop like before. I did notice that while I was going through the ultra fines it was alot harder for me to hold a close to perfect angle since I was trying to put very light pressure on the stones. So I barely had the knife in my hands. It seemed to waver some. Does it take a little more practice to learn how to use the ultra-fines stones???? Also one more question looking through my 60x microscope the sharper part of the knife is not as shiny as the other not as sharp parts of the knife. In the middle of the blade is where its like this. Closest to the handle and the tip is really brightly lit up under the microscope. In the middle where its sharpest its not as shiny. Is this the way its supposed to look?? Is that one way to judge sharpness??
