I do not think that either will be very good. Both will scratch extremely fast, and after a short time would be pretty unsightly. Plus, it may break around the pivot after a little while. A bali's tang fork is a relatively small amount of material, and would not stand up to the stress for long. In addition, the tang pins would destroy the cups in the handle when latching it open or closed. The handles on the bali would be far too light for balance, so it probably would not flip at all.
A stiletto may work, but you may want to direct that question to the automatics forum. I don't know enough about how they are built to make a good suggestion.
Be cool if you manage to work it out, post pics if you make it work.
