The Stay Sharp Broadhead Sharpening Guide is all you need to return the edge on your broadheads to the razor sharp cutting edge you need for quick and humane kills. All of Stay Sharps roller guides can be modified to increase the angle by wrapping the rollers with tape. Use as much or little (or none) as you wish to reach the angle you desire. Do not apply so much as it causes the roller to bind.
The Stay Sharp Grey Guide is specifically designed for Zeus and Magnus Stinger, Buzz cuts, Iron Will Double Bevel, Alien Double bevel heads and other broadheads.
The 32 Degree Guide is designed for Single Bevel Iron Will and similar Broadheads
