Ive trapped a lot of beaver myself..A good beaver knife needs to be fairly thin and have that round nose sharpened all the way around to the top..Beaver are one of the hardest animals you'll ever skin and worse to flesh. Skinning around the head will dull a knife fast.
The reason a beaver knife is round is because beaver have to skinned in the "round" vs "cased" for most furbearers..You have to be able to push the knife under the skin between the folds. A pointed knife pokes holes in the hide to easy..
I also suggest a very grippy handle. Beavers are very fat and oily. Everything gets hard to hang onto.
Yes a description would be a big help! Since I know the OP is into black powder this maybe a beavertail dag being requested rather than a skinning type knife........
If a dag I can help with line drawings as well as pics.......
