The Swhacker 307 Mechanical 2-Blade Broadhead delivers a 100-grain mechanical design built for repeatable accuracy from practice to hunting. Its Blade-Lock system lets you lock blades closed for target shooting or unlock them for full deployment in the field. An anodized aircraft-grade aluminum ferrule, hardened high-carbon steel point, and 0.031-inch stainless steel blades provide a durable, sharp cutting system. Slice-Twice uses wing blades to start entry, then main blades open inside for a two-stage cut.
