Slingshot
Nunchukus
Sai
Pick Axe (surprisingly no one has this on their default skin...)
Escrimas
Tonfas
Tazers/Stun gun (Heimer's grenade counts as a flash bang)
PepperSprays
Just go ahead and give 
any of these for christmas
doesn't shen use sai's?
Whip Brass Knuckles type weapon
A slingshot would be interesting... He/She could rely on ammo....
I'll allow sais on the condition that 
hard-counters whoever uses them.
