GRS® GraverHone One

Take full control of your sharpening with the GraverHone One, featuring a digital display and refined variable speed control for precise sharpening. The easy-to-read digital RPM readout not only gives you exact control, but also ensures consistent, repeatable results—so you can sharpen the same way every time without variation. Whether you’re roughing, sharpening, or polishing high-speed steel or carbide gravers, this powerful hone delivers smooth, accurate performance. Its high-torque, American-made motor ensures exceptional reliability and long-lasting durability. While the speed range is 400-1400rpm, it is not advised to run abrasive wheels (not included) above 900rpm due to accelerated wear, heat buildup, and rapid material removal from the graver being sharpened. Please note, unlike other GRS offerings, the GraverHone One does not come with a grinding wheel.
