Pivot location on folding knives

[Boothknife]

I have a question, hope this is the right place to ask it: Does it matter where the pivot point is located as long as when the knife is open the blade is in the right place, and when it is closed the blade is in the right place? Most folders seem to have the pivot point fairly near the center of the bolster, but on my knife design, the blade is quite wide (one inch and an eighth). I am trying to use a Lockbar Integral Tension Spring, and the blade will not fit into the handle using a centralized pivot point, but when I lower the pivot point considerably everything works fine, on paper that is. Any advice?

I'm not sure what that Lockbar Integral Tension Spring is, but for me, as long as the spring is flush with the liners in the open, closed, and half-stop (if there is one) positions, the action is smooth, and there is some snap both opening and closing the knife, the position of the pivot doesn't matter.

I'd say if it works it's fine.
Some knives with a spring on the back that locks over a nub on the tang will have the pivot rather low.
You might try a knife-maker's sub-forum.

A low pivot pin is normal on many designs, it doesn't really matter as long as everything fits properly.

Thanks, everyone for all your help. The "Lockbar Integral Tension spring" can be seen in the book: How To Make Folding Knives by Ron Lake, Frank Centofante, Wayne Clay. Ron Lake uses the Lockbar Integral Tension Spring method.
