Microtech UDT style 5.5 inch Modern coilspring automatic knife black

Microtech UDT style 5.5 inch Modern coilspring automatic knife black. Very similar to the Microtech UDT automatic knife, these were sold in the 1990s by a prominent knife dealer in Florida. Can't remember what they called them? It measures 5.5 inches open with black aluminum frame and crosshatch rubber inserts for great grip! No markings on the knife. Blade has slight loss from sharpening. Coil spring fired and works great. These sold for around $100 in the 90s as I recall.
