The Mr.Hobby GT65H (Mr. Line Chisel Replacement Blade 1.00mm) is a 1.00 mm-wide replacement blade for the Mr. Line Chisel, a proprietary scraper tool from GSI Creos. Made of high-quality hardened steel, it is designed for cutting very wide panel lines, deep machining grooves, modeling hatches, or forming large dividing panels on plastic scale models (airplanes, armored vehicles, or Gunpla robots). Thanks to the special shape of the tip, the blade provides excellent control during use, creating a perfectly straight and wide groove with smooth edges free of burrs, and the substantial 1.00 mm size makes it an indispensable tool for complex custom scribing, working with large scales, or recreating clearly visible structural elements of the hull.
