A jig to dress watchmaker / precision screw drivers using readily available rolling sharpener and diamond laps.  

Jig and plate holder are modeled around the two following items from Amazon:

Screwdriver holder - [https://amzn.to/4eXF09G](https://amzn.to/4eXF09G)

Diamond laps - [https://amzn.to/4gyRUfE](https://amzn.to/4gyRUfE)

Simply set the diamond lap in the jig, place the screwdriver that needs dressed so the flat is evenly against the lap, and roll back and forth.  Once the flats are dressed, drag the tip along the lap to adjust the width of the tip.
