Abstract: The personal weapon includes a base and blade support pivotally attached to the base, with a plurality of blades extending from the blade support. The assembly is installed across the upper palm and adjacent bases of the fingers of a glove, with backing plates providing additional reinforcement for the assembly. The blades extend selectively as the palm is opened and the fingers extended, with the blades retracting into slots in the base when the fingers are closed over the palm. The device extends only across the second through fourth fingers, leaving the index finger free for e.g., firearm trigger actuation, etc. independent of blade deployment. A thumb-actuated safety is also provided to lock the blades in their retracted positions. The glove may be fingerless or partially fingered, or may include complete, fully enclosed fingers.

Abstract: A rotational power coupling consists of drive shaft couplings and stationary housings within which the shafts rotate. One housing has a flange with external threads; the other has a plain flange. A threaded nut engages the threaded flange and draws the two flanges together, locking the housings. The nut is surrounded by a collar which can rotate about it. A handle extends from the collar. The nut has external teeth, and the collar has oppositely directed pawls. When the pawls engage the teeth, the handle may be used to turn the collar.
