Consistent arrow flight starts long before you reach full draw, and it starts at the prep bench with tools that actually do the job properly. The Last Chance Square Up Arrow Squaring/Spinning Tool combines two critical arrow-building functions into one precision-milled device: a high-quality spinner for checking shaft straightness and a diamond-hone squaring tool for ensuring your inserts and shaft ends are perfectly perpendicular. Where most squaring devices rely on sanding discs or replaceable cutters that wear out and need swapping, the Square Up uses an adjustable diamond insert that can handle hundreds to thousands of uses without degradation. It is the kind of tool that pays for itself quickly and earns a permanent spot on any serious archer's bench.

Last Chance Square Up Arrow Squaring/Spinning Tool Key Features

• Adjustable Diamond Hone Insert: The squaring face uses a diamond abrasive rather than a sanding disc or replaceable cutter, meaning it maintains its cutting surface across hundreds to thousands of uses with no consumable replacements required. The insert is removable and adjustable, allowing you to switch the tool between squaring mode and spinner mode quickly.
• Two-in-One Functionality: Operates as both an arrow spinner and an arrow squaring device in a single tool. Use the spinner function to check shaft straightness and component runout, then switch to squaring mode to dress insert ends and shaft faces square to the centreline.
• High-Quality Bearings: The spinner component runs on precision bearings that deliver smooth, consistent rotation, giving you a clear and accurate read on any wobble or runout in your shafts, inserts, or nocks.
• Precision-Milled Construction: Machined to tight tolerances to ensure the squaring face is true and the spinner rolls without false wobble. The quality of the milling directly affects the accuracy of both functions.
• Bench-Mountable Design: Includes 2 lag bolts and 2 washers for permanent or semi-permanent attachment to a workbench or table, keeping the tool stable and correctly positioned during use. A fixed tool means consistent, repeatable results every time.
• Covers Shafts and Inserts: Suitable for squaring both arrow shaft ends and inserts, making it useful at multiple stages of the arrow-building process rather than being limited to a single task.
• Made in the USA: Manufactured by Last Chance Archery in the United States, under the brand's reputation for precision archery preparation tools.

For compound and traditional archers who build their own arrows or tune their setups closely, the Square Up is a straightforward investment in consistency. Properly squared and straight arrows reduce contact inconsistency at the rest, improve broadhead flight, and take one more variable out of the equation at the target.
