Lansky Large Flat Bottom Handle

I modified the handle to accept stones which are approx 150mm x 20mm. These are readily available on eBay and Amazon and can be removed from the plastic backing. The stones are sometimes called ADAEE which is a good keyword to search for.

I scuffed the bottom and used some two part epoxy to glue them to the handles, taking care as the clamps want to make the stone slide.

The thumb screw hole is M4 and I used these unshouldered M4x10mm
