Do any of you use this? Is it just another one of those products that are hype, or does it really make a difference? I'm torn.
Absolutely, great tool for squaring the arrow before installing the insert, secondly, turn the head around and square the insert after it is installed. This gives you a square end to install the broad head. All help in attaining good arrow flight. Good luck!
I also have an ASD and use it on every arrow I build. However, I would like to pick up a FAST tool from Lumenok at some point. It allows you to square the back end of your arrow after it's been fletched if need be. I've needed to do this a few times in the past, and this would've really come in handy. http://lumenok.net/shop/Accessories...etched-arrow-squaring-tool)/product_info.html
I square the back end when I build the arrow but I have never had the need to resquare it afterwards. What kind of scenario has you needing to resquare the backend while fletched?
