HSGM Type STA Heat Cutter Blade - This is another multi-purpose blade that can be used in a variety of applications with synthetic material. The whole "V" shape of the blade becomes heated and the working area has a more pointed tip. The outer edges of the “V” shaped working area has a slightly sharpened edge, but remember that the sharpened edge is not for cutting like a steak knife. The sharpened edge is only to assist the heated blade in separating the material while the heat does all cutting and sealing. 30mm or 1.181 inches of working area. The HSG-3-VW (H/125) is the recommended unit to power this blade to achieve a satisfactory cut and seal. Blade sold individually. 1/4" thick glass is the HSGM recommended cutting surface for all cutting table. Made in Germany.
