This makes it easy to put broadheads on tight and later easily remove them, safely. Sure, as others have mentioned, you could just use your fingers to tighten your broadheads, but this wrench keeps your fingers off those razor blades. Construction is top-quality. I use this on my Muzzy 3-blade broadheads and it works perfectly. Another reviewer mentioned that it doesn't work on 3-blade broadheads, but it works easily for mine.
Extremely helpful and useful. I can finally stop the accidental cuts that happen when setting up my arrows. I'd greatly recommend this product to anyone who has felt the unintentional sting of a broadhead cut.
