Man those are nice ones Robin.
Since I started this thread I've gotten another. This one is about 3/4 the size of my other. He made a bunch of smaller ones to make then easier to carry in a pack.
My favourite user has a very short blade with a basic elbow handle, it's an old Mi'kmaq knife I bought years ago in Nova Scotia.
I have watched a couple of Algonquin bark canoe builders use a crooked knife but most use pocket knives nowadays.
Your friend makes nice crooked knives, is the bone handle made from Moose antler?
Best regards
Robin
