Mr.Hobby GSI-GT65I 1.2mm Replacement Blade for GT65 Mr. Line Chisel  [GSI-GT65I]

Replacement blade for GT65 chisel

The GSI-GT65I is a single-purpose 1.2mm replacement blade designed for use with the GT65 Mr. Line Chisel, offered by Mr.Hobby as a direct spare part for RC-scale model scribing tasks. It is intended solely as an RC accessory and should be used only with compatible GT65 holders.

Fit and compatibility are straightforward: the blade matches the GT65 blade slot and is sized for the GT65 Mr. Line Chisel system. When replacing the blade, follow the chisel holder's retention method to seat the blade securely; ensure the holder is clean and the blade edge is oriented correctly before applying light test strokes on scrap material.

In practical build and tuning workflows this blade serves as a repeatable scribing tool for panel lines, surface detailing, and trimming fine edges on body shells and scale parts. Routine inspection of the cutting edge and conservative pressure during use help preserve blade life and maintain consistent groove depth across multiple passes.
