This is mostly just a quick short list of suggested equipment.
Gauntlet, Clawed
The Clawed Gauntlet is a martial weapon, and doesn't suffer from the normal effects that the other gauntlets do. Does 1d4 slashing damage with an 19-20x2 crit. Cannot be disarmed. It gives a +1 bonus to climb (possibly item) This stacks with other clawed gauntlets. (So if you have two arms, you can wear 2 and gain a +2 bonus.)
Whip, Chain
Everything of a normal chain, but deals lethal regardless of armor. heavier than a normal whip and deals bludgeoning damage.
Whip, Thorn
Same as the chain whip, though in between in weight of chain and the normal whip. Deals Piercing damage.
Hair Knife
Deals 1d4 x2 crit, P damage. Is worn on a long pony tail, and requires exotic weapon prof. Can be used even if hands are full as an additional attack even at a -5 penalty to the attack.
