I was wondering of coming up a knife design that would give you the safety of a balisong or fixed blade, while still defining itself as a slip-joint for UK users.
So the design would be a regular folding knife, but the tang extends beyond the handle scales of the knife itself. When flipped open, the fingers and the grip of using the knife would lock the extended tang of the blade into position.
It's somewhat hard to explain so here's a VERY ROUGH mock up of such design.
The one on the left is not open and the one on the right is deployed. (note, the tang is extending on the wrong side of the scales, I just realized that the extended tang should be on the top (or from this perspective the right) side of the scales.
As you can see, all I'm devising is a rotating full tang (or half tang for that matter) fix-blade, although the function of such a design would dictate that it is still a slip joint. My question is that if such a design was to be out, would it be called a fixed blade or a slipjoint legally?
There are no locks other than the one given by the user of his grip of the knife.
I realize there is no practical point in design this knife from a engineering standpoint as the whole idea of a pocket knife is the cut out the tang portion of a fixed blade in order for it to be more portable, but legally I could see this knife creating some sort of loophole over UK law.
What do you think?
