BSC Tools says:

For quick and easy wheel lacing in conjunction with our Shuffler Box, the LT-14/13 grips spoke nipples firmly due to the taper.

CNC machined from stainless steel with an interference fit double sealed 626 bearing installed at the end to allow the tool to spin smoothly in your palm.

The tool is knurled for grip and is 7mm diameter at the knurl.
