Got the manly wasp in s90v. Came with a nice working edge on it. Used it for 2 days. The hardest thing I cut was some small diameter fuel line. It's got flat spots all over the bevel. I just hit it on the 325 DMT to leather with diamond spray. I'm seriously disappointed that the edge degraded so quickly. I emailed the company. Let's see what happens. Going to work it tomorrow and see. I think it's a dud but too early to tell. I have 440 c knives that get along much better than this .
