Check the listing for details. Swhacker #243 SWH00243 2 Blade 150 grain 3" Cut - 3 Pack. Color: Black, Condition: New. Listed at 43.92 USD. Swhacker’s slice-twice blade design provides you with two separate cutting edges. The first set of edges, the wing blades, are used for cutting the hide and the first set of ribs. These blades are also used to open the broadhead and are much smaller than the main blades. They take the most punishment by cutting through the hair, dirt, hide, and bones during entry. The smaller wing blades require less energy to penetrate than an “open on impact” broadhead. The wing blades also provide a load bearing surface for the ferrule during impact. The second set of edges, the main blades, are not dulled by hide or bone during the initial penetration. This allows the main blades to remain razor sharp when they open inside the body cavity, wreaking havoc on muscle, tissue, and organs.
