Spyderco named this knife after its principal job function- to assist. The Assist is designed for emergency/fire/rescue professionals who rely on their knives to function flawlessly under pressure. The blade is made from VG-10 stainless steel and loaded with teeth. The VG-10 patented blunt-tipped blade is a toothy eighty-percent SpyderEdged for aggressively cutting seatbelts and fibrous material. The last inch of the tip Spyderco left PlainEdge for detailed cutting (think sharpening pencils). Other awesome features include: retractable carbide tip for breaking glass, attention-pitched survival whistle, carries left/right handed, tip-up by means of a tension wire clip. Blade length: 3.7". Overall length: 8.4". Weight: 4 oz.
