No one has mentioned them yet, but how about a Bird/Trout Knife? Depending on the manufacturer, a 2 to 2.5" blade, and the handle is a simple shaft ending in a ring for your pinky. Think a really light, slender, fiked blade kerambit with a stubby little blade. Wrap the spine with paracord, and you are good.

I'm not terrifically fond of Cold Steel, but their's might be the most accurate to the old Marble's origional: http://www.eknifeworks.com/webapp/eComme...;amp;SKU=CS20BT

If you go to ren faires, I've never been to one that didn't have a knifesmith selling thier own version of these guys, usually pretty good ones.
