The Log Shaping Disc as its name implies is ideal for log shaping. The Log Shaping Disc takes shavings off logs 1/4" to 1/2" wide to about 1" long. The Edge of the Log Shaping Disc can be used for design, detailing on wood carvings and cuts like a circular saw. Special heat treatment allows the Log Shaping Disc to be sharpened with proper tool (sharpening burr). Can be sharpened up to 25 times for full life of disc.
