FAQ

 Why are SilverFlame broadheads not available with the "Single-Bevel-Cut"?

Blades cut on one side produce a rotation of the arrow when penetrating, which will leave a slightly enlarged opening when hitting bones and therefore produce less frictional resistance for the arrow shaft. This may lead to a bigger depth effect than a blade with a "double-bevel-cut" might have caused.

However, please keep in mind that the additional rotation and the "milling away" of the bone material will cost additional strength and energy that will then be lost for the depth of penetration. Furthermore, blades cut on only one side deliver an insufficient "cut-on-contact" due to their geometry. The tip resembles “the appearance of a screw driver”, and is therefore very difficult to sharpen. In our opinion, single-beveled broadheads only make sense when relatively thick arrow shafts are used.

We recommend an arrow shaft diameter that lies as far as possible below the biggest diameter of the broadhead (8.5 mm for SilverFlame broadheads). Modern carbon fiber shafts, especially the slim HIT-shafts by Easton and Beman, have shown themselves to be highly efficient. With them, the frictional resistance is minimized without wasting energy for the penetration.

When using HIT-shafts we recommend “Broadhead Adapter Rings” (Easton B.A.R.s) to provide the broadhead with the utmost support (shear stability) on the thin shafts.”
