One of my knives that was sold as a second came back for sharpening, so I was pretty excited to see how it did. It was used as the main knife for one of a crew who were butchering several moose. There is nothing concrete to say about it, as it was cutting a combination of meat, gristle, bone, dirty hide, etc. He was really pleased with the performance though, so it will be sharpened up the same way again.

I had put a polished edge on it, so was surprised it did as well as it did, but am thinking that most of the work probably benefited from it. At 100x most of the edge had blunted, over a goodly portion had become even more polished through use. There was some fracture that was along the edge, .001-.003"? deep, no edge rolling. Also some nicks that were likely lateral stesses just in front of the handle and near the tip. He didn't want me to go to a coarser edge, as he prefers the finer one. The fine edge may be helping strengthen the edge, anyway. He does this often, but doesn't mind working the knife hard.

Anyway, it was CPM154 at 61rc with .030 edge at 15dps.

Any Cal.,
Nice work! Can I ask the grit progression you used?

Sure. And I may be wrong about the polish from use, I could have been seeing some of the fractures reflecting light.

It is typically 220 AlOx off the grinder, then 1k and 5k Shapton pro and a kiss on the Spyderco UF rod. Mostly just wanted the edge to have an impressive bite when it was for sale, wouldn't necessarily have been the way I would have sharpened it specifically for butchering a whole bunch of critters.

Nice! Moose are big, if it did more than one, from hunting stories I have read and in knife magazines, that's good performance.

That looks like a great design. Nicely done.

Nice looking knife and feedback from the customer.

I got this one back, and resharpened it to 600g diamond with a Spyderco UF bevel. Customer didn't like it at all compared to the earlier sharpening. Would have thought the 600 would last longer through gristle and such, but apparently the lack of pushcutting hurt it. FWIW...
