Abstract
Abstract A finger actuator is provided for attachment on a conventional knife blade of the sort which is folded into the handle when not in use. The actuator comprises a resilient tool steel saddle arrangement fitted very tightly over the knife blade. A first plate extends upwardly from said saddle in a direction away from the edge of the knife blade and then extends outwardly in a direction substantially transverse to the longitudinal axis of the knife blade to provide a flat plate area against which the thumb pushes to open the blade while the other fingers of the hand hold the handle in the palm.

Total Claims: 3
Claim 1
Independent Claim
179 words
In a knife actuator for a folding knife having a handle and a blade folded thereon for movement from a folded position to an extended position, said blade having a cutting and a non-cutting edge, said knife actuator comprising: a pair of resilient, spring attaching plates attached along a common line which is positioned substantially co-extensively with and for attachment to the non-cutting edge of the blade, actuating means on said attaching plates comprising a first member extending upwardly on one side of said knife blade and said first member then bending outwardly substantially perpendicular to th knife blade providing a flat finger plate for operating said blade by pushing said plate with the thumb while holding said knife in the same hand as the thumb, said attaching plates being mounted by being manually urged apart against spring action in order to position same over said knife blade whereupon after release said plates spring tightly into place thereby holding said plates firmly in place on said blade, and said plates being manually slidable on said blade to adjust same.
