Hinge-pin options on a balisong?

[Destichado]

This is my first time out the gate on a butterfly knife (why hello there, Mr. Learning Experience!) and I'm assessing my options.


I'm a bladesmith, not a machinist, so I'm afraid my tolerances are only as tight as my eye and my files have made them. Right now I have a rather robust roughed-out balisong sitting on my desk, riding on temporary rivets, and I'm wondering what the experienced makers use.

Hard rivets, of course, are always an option. Perhaps not a very good one, but an option. And chicago screws are the other obvious one. But, I'm always looking for a better solution, so is there anything out there I ought to know about?

If you go to somewhere like knifekits

or most any knife supply they sell folder pivots. Check out a few places as there is a variety. Some people also drill out the blades hole and install a bushing. There is also a system where you machine a groove around the pivot hole and install small bearings.
