Maintain sharp knives with the Professional Combo 240/1000 Grit Whetstone by Edge Master, designed to keep your hands safe and knife edges in pristine condition.
It includes two whetstones of varying grits: resharpen your damaged or extremely blunt knives with the coarse 240 grit, and resharpen dull knives and remove burrs with the medium 1000 grit. It also comes with a non-slip base for ultimate control.
Submerged in water for about 5 minutes - or until bubbles are no longer forming - before use, then sharpen your straight-edge knives at a 15 to 30-degree angle through a constant back-and-forth motion.
