I’ve started researching my issues with the S110V blade I have and found that pretty much no other user had the same issue I have. Not with a Spyderco, nor with any other brand using S110V. I have since sharpened the blade 3 times, thus completely removing the original factory bevel and any steel that might have been overheated or had any other problem out of the box.
The knife had an edge at 16DPS, finished on a 8k Shapton glass stone and then stropped very lightly on 0.3 micron AlOx on horse leather. The resulting edge passed the HHT 3 and I didn’t see any burr under magnification.After using the knife for a few minutes cutting cardboard boxes (maybe 15 cuts) the edge showed tiny chips. Some of them I could see with the naked eye under artificial light, but all of them could be felt by dragging the edge over my finger nail.
If Spyderco messed up the edge, my repeated manual sharpening should have fixed this issue. The edge angle isn’t too low imo, but I raised it in my next sharpening session to 18DPS in an attempt to fix this issue.
The edge showed the same deformations after 12 cuts in cardboard. I checked it under a scope and it looked like exactly like before. As a final resort, I made a compound edge of the 2 previous angles, and added a 19DPS bevel that I then blended with 0.3µ AlOx forming a convex edge that zeroed in at 19DPS approximately (no real way to measure it perfectly). This is the only edge that has held up to 15 cuts in cardboard.
So far this edge has held up pretty well with a lot less chipping than the previous edges. In all, if this is the only way I can get CPM S110V to work, it’s a steel I rather not see becoming mainstream.
