"A square edged-crank."
Square Crank is a key item in Resident Evil 3: Nemesis.
It can be used near Bar Jack's backdoor to open a storage shutter and reveal three packs of Grenade Rounds (explosive). Therefore, this item is very valuable on hard mode, but it's not necessary to obtain or use it to complete the game. It disappears from the inventory after using.
This crank can be found in the alley near the Sales office in uptown.
