Come on! We military types would likely call it hand to hand combat - or a "dumb attack". Those darn dumbs is dangerous.
Btw, a tear gas grenade has -2 second fuse!! Trust me on that one! Been there done that! I'm a bit too far off to offer any hands on aid, but the thought is there. I know the healing process and the therapy regimen - just had my thumb rebuilt last winter, almost back to full function, but can sure tel, weather changes! Keep us posted, and if it hurts when you do that - don't do that.
