This kit is suited for those getting started with watchmaking. Including all the equipment needed to shape screwdrivers & tweezers. The kit is compact and optionally compatible with the Gridfinity sorting system for easy organization. The included diamond stones remove material significantly easier  than India stones while maintaining a higher finish making a screwdriver a 2-3 minute job to sharpen finely.

3x Diamond stone plates (400#, 600#, 1000#)

1x Screwdriver holder

3x Fastening Shims (To secure plates during use)

1x Storage Box & Lid

Updated Design 16/7/2025: Upgraded screwdriver holder to an improved 3D printed design with better reliability than the generic version.

Diamond-stone: Lower finish quality, but a longer lasting abrasive.

Lapping Film: Very high finish quality, but the film can wear out with use.

I always keep one of these kits in arms reach on my workbench, I find myself using it constantly as it's faster and easier to use than India stones. The diamond stones work well dry (Windex also works well), and can just be lightly brushed into a bin when clogged.
