Limit 2 hand swing speed

High damage weapons help as wel. I recommend the military cleaver. Great weapon.

I have a tempered military cleaver and it will still sometimes bounce when face hugging. 
On the other side, maybe it's only me, but I'v seen it happen less often then when I was using the scimitar...

Shorter weapons rarely bounce, picks, axes, etc. their sweet spot is basically right up in your nose, so the typical bounce trickery doesn't work.

Most of the bounce tricks involve really maneuvering in such a way your hit hits too early in the animation and ergo does nothing, or you launching a attack on the wrong side and hitting too late in the animation. Positioning.
