Im looking to replace a mini trapper that my father inlaw carries. Its scales are broken off and the blades are sharpened down to almost nothing. He says it has good old steel the blades will turn black when he cuts up an apple and will stay sharp after he scrapes wire with it. So Id like to get him a carbon steel blade or even one of the Queen D2 may work, no stainless. The only other knife he has carried was a single blade long trapper style he took off of a German back in WW II. His hands are getting kind of week example I gave him a Queen #11 D2 and he had a lot of trouble opening it. So Im not real sure what to get for him. Any suggestions on an easier opening pocket knife that would give an old pocket knife guy a smile?
