I have 3 of his knives, a blue mammoth ivory small skinner, a large coffin handle Bowie, and a medium size sambar stag Bowie. His knives are solid and beautiful. I have only used the small knife much, and it worked very well for whittling. Its edge held for quite some time. They aren't just for show.
I've been waiting for the right oosik handled knife to show up.
