Name: Flip-to-Slip Mechanism Conceptual Drawing

Subject: Falisong



For the balisong flip-knife, the attachments pivot the bite handle and the safe handle around two axis, attached by a latch to create a triangular set of joints and further strengthened by a tang pin. Though sturdy, these sets of pins can still be vulnerable to breaking.



Sliding knives work with a different principle. A double-action OTF knife moves across a channel, with two attached spring carriers, which have tabs that restrain one or the other carrier in the open of closed position so that, when tension is applied and the tabs are loosed, the knife slides out the front or slides back into the handle. This movement is vertical restrained by the channel.



Both mechanisms are vulnerable to parallel stress as well as perpendicular stress, which is why they are intended for light use. However, in the design illustrated above, the safe handle of the balisong flip-knife is replaced by a channeled alternative with an automatic OTF mechanism.



Comparitively, this synergetic design is marginally more vulnerable in the thrust than the true balisong and somewhat sturdier in the cut. Compared to the automatic OTF, however, the vulnerability is theoretically significantly reduced, making it tougher in both departments. I would argue that this is a net gain in strength.



Additional notes; the safe handle wouldn't have the tabs oriented across the side of the blade like a traditional OTF, but across the back, to free up room for the bite handle. The thumb-stud is ommited entirely, in favor a sun-and-planet gear assembly revolving around the balisong axis that activates the automatic OTF component.
