Professional Non-Slip Adjustable Whetstone Holder - Chrome Plated Iron & Silicone Base for Sharpening Knives, Tools - Perfect for Kitchen, Workshop & Outdoor Use

I pride myself on my knife sharpening abilities, having been trained by the Japanese Knife Company on one of their one-on-one training courses. I have three Japanese water stones and regularly sharpen my knives to almost new keenness.To that end I need to clamp the water stone firmly into a cradle that doesn’t slip about while I am stroking the blade along its surface. This device has blocks of rubber that both clamp the stone in place (with knurled wheels to tighten them) and grip the work surface so that everything stays in place.I would have preferred a Naniwa sink bridge but they’re hard to find here and are outrageously expensive when you do. This is a good quality compromise.
