62 hrc Spyderco M390 PM2 edge retention testing, this is what the hype is all about

Published: 5 years ago

BBS PM2 M390 at 62 hrc edge retention testing. I ran this 3 times to double verify the data point. This is what we should all expect out of M390, not the 57-59 hrc we see all too often from production companies. I will be doing a bringing it back with this before I sharpen it again. I had no idea it would put up this performance and I couldn't be happier about it.
