Sharpens the chain while it stays on the bar - mount in 60 seconds and start sharpening.
Runs from any 12V source: your truck battery, a jump starter, or a portable power station.
Sharpens all types of Chains (Crosscut, ripping chain, and skip tooth). Works with Stihl, Husqvarna, Echo, and all major brands.
You can adjust the angle, file height, and tooth length to get the most accurate cut. Bar-mounted design locks the grinding angle - every tooth sharpened identically, no guesswork. Just pull the chain through the groove of the bar and sharpen away.

GRANBERG HISTORY: "Elof Granberg introduced this as the FIRST handheld 12-volt sharpener to the chainsaw accessory market in the ’70s. Why is that important? We originated the tool so we’ve had longer than anyone else to develop it and we set the standard. Every other bar-mounted grinder is a copy of the standard we created!" -Granberg International
