Hey guys. I have a British racing green, ZPD delica 4 that has been carried for about a week, and an Endura 4 that is like new, that I would like to trade for either a Benchmade Ritter mini grip,of quality slip joint knives. Specific slip joint brands I'm interested in are Queen(mainly QCCC), Schatt and Morgan, GEC, Northwoods, and older Case. I'm only interested in the knives mentioned above. Let me know what you have, and I can send you a few pics. Thanks for looking. mdsmith1979@yahoo.com
