A simple to operate hand held device for precision sharpening of most modern ice screws.
There are two points were the ice screw is inserted, one to sharpen each side of the tooth. Each tooth needs sharpening in turn by inserting it and moving the slider up and down 4 or 5 times. So for a typical 4 toothed modern steel ice screw you will need to make about 40 movements of the slider to complete the sharpening process. To remember which teeth you have sharpened it is best to mark them with a felt tipped pen.
Naturally, the device is optimised for Petzl screws but will also work with Black Diamond, Grivel etc. though you may need to check such other makes of screws for burrs on the edges which will need to be removed with another file.
The high quality file in the device is reversible for extended life and the device is guaranteed for 3 years
Made of polypropylene/hemp and a steel file.
