The Last Chance Archery Square Up high-precision squaring device and arrow spinner tool uses an adjustable diamond squaring insert that is an excellent solution for squaring arrow shafts or inserts. This tool can be used hundreds to thousands of times without wearing out the diamond insert. With other squaring devices, the sanding disc or the cutter must be changed out after limited use, not with the Square Up. Combining the diamond insert with high-quality bearings and a precision-milled tool, provides an effective combo to help build the most accurate arrow possible, which means more success in the field. The kit includes the Square Up Squaring Device and Arrow Spinner tool, lag bolts and washers. MSRP: $56. Contact: www.lastchancearchery.com
