Spyderco was founded in 1976 by Sal and Gail Glesser. Spyderco’s first knife-related product was the Tri-Angle Sharpmaker. Originally sold out of a converted bread truck, it remains one of our best-selling products over 40 years later. Spyderco pioneered the modern folding knife, introducing now-common features like the pocket clip, serrated edge, and one-handed opening capability. Today, that creative spirit and an uncompromising commitment to quality are still the heart of Spyderco's distinctive product line, which includes a full range of folding knives, fixed-blades, sharpeners & other accessories produced in 5 different countries. The Double stuff is a 303F and 303M bonded together and packaged in a leather pouch offering a variety of sharpening options. This pocket stone fits in the palm and has both medium and fine grits packaged in a leather carrying case. It is autoclave safe (ideal for dental tool sharpening) or can be cleaned with a plastic scouring pad and powdered abrasive cleanser. This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
