The Schrade Guide Master Sling Shot Knife features a black titanium coated stainless steel blade with TPE rubber scales for outstanding grip in all conditions. It's the integrated slingshot that sets the SCHF39 knife apart from all others. Housed within the grip panel of the GFN sheath is an elastic sling, which attaches to the fold-up prongs. Adding to the ingenuity of the Schrade Guide Master, is the built-in ammo magazine with six 12mm ball bearing shots. Add to that 120 and 600 grit sharpening stones and a ferro rod, you've got more than an impressively versatile fixed blade and sling shot setup.
