Hautboy staple trimming tool
This tool is for trimming an existing staple, at the top or at the bottom. It works both ways: enter the length to remove and it gives the staple's new diameters; enter the diameter you want and it gives the length to remove. In both cases, it also shows the trapezium corresponding to the trimmed staple. Trimming a staple does not change its taper. To go from a staple to a trapezium, see also the hautboy staple calculator.
