Featuring 100% Carbon Steel, the Montec CS retains edges longer, is 25% sharper than the stainless steel Montec, and is easier to resharpen. The Montec CS broadhead's foolproof design combines tough one-piece, all-steel construction with 100% spin tested accuracy. With no components to assemble or replace, simply screw on and shoot. This simple-to-use, high-performance broadhead is what every hardcore hunter is looking for. Note: Unprotected carbon steel rusts readily when exposed to air and moisture.
