I find it remarkable how they were able to get such tight-fitted scales without any gaps. In my own lack of experience, (I use the peened pins also) I find myself using epoxy more just as a filler for those faint hairline gaps between scale and tang. To get this perfect is a skill in itself. Do you find people you sell knives to more or less attracted to the rough finished blade look. I for one, like the rugged look of the knives you posted. I am not a fan of the typical modern day mirror polished stainless steel knives. Any time I pick up a knife that looks too shiny, I look for the Made in China stamp. I like the fact that you utilize convex ground edges on the blades without the choil area. It seems to make for a more fluid looking knife. Doesn't having a choil in a blade just cause a stress riser anyways?
Anyways, sorry to hear about you're recent loss of a good friend. You have my condolences. Randy.
