Patent number: 10131059Abstract: Folding knife embodiments are disclosed herein comprising a blade operable to pivot relative to a handle, between an open position and a closed position, a blade-locking member disposed in the handle and being moveable in a first direction between an unlocked position and a locked position to retain the blade in at least one of the open or closed positions. The folding knife may further comprise a safety member mounted on the blade-locking member and being moveable relative thereto in a second direction between a release position and a safety position. Wherein when the safety member is in the safety position, the safety member and the blade-locking member are blocked from moving in the first direction, and wherein when the safety member is in the release position, the safety member and the blade-locking member can be moved in the first direction to move the blade-locking member to the unlocked position.Type: GrantFiled: October 30, 2015Date of Patent: November 20, 2018Assignee: GB II CorporationInventor: Flavio Yuji Ikoma
