HSGM Type HS-SG Heat Cutter Blade - Cutting blade similar to the HS-S, with a smaller "V-shaped open mouth" and no "foot". The V shape in the middle of the blade is the part that heats up. This blade is also excellent for larger width materials. The HS-SG blade works like an open pair of scissors; just get it started and push the blade across to the other side of the fabric.
