The 531-131 Pardue is an excellent addition to Benchmade's Gold Class line. This knife is based on the thin, lightweight 530 folder. It features a titanium handle with Timascus inserts front and back along with a soft-spoken texture along the flats of the handle. The blade is coated S90V super steel blade marked on back with the serial number. This is a very limited run of just 70 knives! This is serial #03.
