The KM RSD-100 (Re-Sharpening on Demand) has tight radius cutting ability. The advantage of a small blade vs. a larger blade is improved maneuverability, and the ability to cut a tight radius corner. It will cut a single ply to multiple ply’s up to ¼” thick. The powerful AC motor cuts like a champ. The carbide tipped blade reduces the amount of sharpening, lengthening the life of the blade, and reduces pull of the fabric. Ultimately this is the entry-level for hand held cutting.
