Best Whetstone Sharpening Stone Holder For Bench Stones

I use this on my custom-built sink bridge. There are small (3/16” or 1/4”?) holes in the rubber underneath, so I added dowels for the fixed end and middle rubber pieces to help keep it from walking/wandering around on my bridge…works as advertised

It works exactly as it’s advertised. It holds your water stones so that they don’t slip. It adjusts very easily. I wondered if the black holder would be soft rubber and not slide well, or hard plastic and not grip well. It was soft rubber that also slides well and the adjusting nuts twist smoothly too. This is a good tool.
