I bought a Wiebe couple years ago cheaper one. Not a big fan of it. Takes forever to get an edge on it hard stainless. I would also opt for the Dexter with a carbon steel blade. My wiebe has taken a backseat to other knives.
Dfabs....which Dunn would you recommend?? I am leaning on a Dunn or a Post (if I can find one)
If you want a beaver knife, I would get a full skinner, but I have not used the small one or any of the other ones. They make just about any style of knife you like though. I've never used a post so I can't speak for it.
Have seen several folks post good results with using Victorinox Beef Skinning Knives for beaver. They are available from Amazon and most restaurant supply websites. I know all of the Victorinox knives I have are good quality knives.
