File handle that fits a Kobalt 6-in Mill Bastard File (K6BM).

The handle dimensions as well as the slit for the file tang (the pointy end of the file) are customizable. Be sure to measure the tang first. I measured mine as 3mm at the tip (TANG_MIN) and 7.7mm (TANG_MAX) at 40mm (TANG_L) from the tip, near the shoulder. The thickness of the tang is 3mm (TANG_W).
