Abstract
An improved hand tool for dispensing plastic fasteners having a novel anvil design that prevents inadvertent user needle sticks during operation of the hand tool and a needle having a novel casing that further prevents inadvertent user needle sticks during the replacement of the hand tool needle. The casing has a needle assembly opening at the front of the barrel portion and a trigger slot at the front of the handle portion. The hand tool further has a hollow needle disposed on one end of a needle assembly. The hand tool further has a trigger that is pivotally mounted within the casing that extends out from the trigger slot. The trigger is capable of moving the needle assembly between the retracted and extended positions. The anvil has a needle guard, a main portion, and a fabric slot. The fabric slot separates the needle guard from the main portion.
