The automatic blade advancement system offers cam-actuated grinding, eliminating the need for manual advancement and making the RS15 fully automated. The feeder arm advances the blade forward automatically while the grinding disc sharpens the face and gullet of the tooth.

The RS15 is powered by a 12V battery (not included), and features a four-legged stand, so the RS15 sharpener can be used in remote locations.

The auto-stop bracket ensures worry-free sharpening by automatically turning off the machine once the entire blade has been sharpened.

The RS15 adjustable outrigging arms can be configured in multiple locations, enabling it to accommodate various blade lengths, expanding your sharpening capabilities.
