MY EYES!

Pocket sand! Sand is smaller to fit in pockets and can be thrown at people's eyes to blur their vision.

Screwdrivers and Forks(in a later PR, more things will be given eyestab()) now use their own force to apply damage, and now is consistent with other weapons by causing knockout instead of "clutching your eyes in pain".

Also, due to bias, don't let aranclanos touch this pr.
