Two knives that are discontinued, but still available, would be a Spyderco Mouse designed by Tim Wegner and a Bencmade Park Avenue designed by Bob Terzuola. The Lone Wolf, Loveless City Knife is also a good candidate. Price range is between 70 to $100. In a lower price range, $40, the Case yellow handled, Warncliffe Copper Lock is a good choice. The yellow handled version is chrome vanadium steel, not stainless. The SOG Blink is about $30 and is one of the slickest little assisted opening knives around.
