Depends. MM is the way to go for anything you can trap: Like I earlier said (in a thread of yours?) its possible to solo them nicely @ 10 MM, and it needs about 50 unarmed to do the same.
For bears MM is also nice, from a boat or using boat traps (they smash through building signs and such), no clue what unarmed you need there.
So, if your quick trapping stuff, go for MM, but know that you will get really good results (effectively killing a boar) only round 40, so it takes a while.
If you want to fight just take up Unarmed. Or trade a weapon somewhere ofcourse

I wouldnt take melee for just a stone axe, btw.
