Whetstones like to sit on a stable, elevated base when getting used, these locally manufactured holders will provide you with a cost effective solution for your Sigma stones. We have allowed recesses to the underside of the base that can accept o-rings (size R22) when added traction on slippery surfaces services are needed, silicone rings work better than rubber, and the newer the rings the more grip they offer. You can also place the holder on a wet towel or silicon pad, or those mats one uses in the boot of your car to stop stuff from shifting around, but whatever you do, but make sure your base is solid and secure before you start sharpening those razors.
*O rings excluded until such time we have sourced some in bulk.
