I like the porcupine a lot. But of the current set, porcupine, frostner & silver sword all have merits & any black metal weapon is perfectly fine and effective. The new claws are better than I thought they would be but they aren't quite cutting it at endgame unless you can get in a backstab.

The axe idea is OK but it has 2 or 3 issues.
- its slow. I get into trouble with wolves against an axe when wolves were still a challenge (early mountain, iron axe)
- if you were cutting down trees, and its getting on towards broken, it can fail if you get jumped / raided/ whatever. Not normally a large problem, but it can happen. More of an early game issue, as late game axes can cut wood far, far longer than you can hold the weight produced.
- it has no special attack, and those are very powerful on the other weapons.

I am probably missing out but I don't do the 2h weapons. The aoe effects only seem useful when exploiting, and too slow when playing more normally.
