I wanted to test this OK-223 (Para 3 style) knife back to back with the OK-81 because they’re both supposed to have the same M-390 steel. The results should be similar, right?

I reprofiled the edge down to a slicey 18 degrees, and it’s cutting paper like a laser beam! But how will it hold up in some real world tests?
I was actually a little disappointed in how this one performed today. But I think I know why…
I picked up a couple of knives from AliExpress that look like the Oz Machine Co Roosevelt. How do these Rosies/“Fosies” compare to the real thing?
