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

GT65 chisel replacement blade

The GSI-GT65I is a dedicated 1.2mm replacement blade for use with the GT65 Mr. Line Chisel, supplied by Mr.Hobby for fine scribing on RC-scale models. It is offered as an accessory and should be used only with GT65-compatible holders.

Fitment is simple: the blade is sized to sit in the GT65 blade slot and aligns with the GT65 Mr. Line Chisel system. When replacing the blade, follow the holder's retention method, keep the seating area clean, and make sure the blade edge is oriented correctly before testing with light strokes on scrap material.

In workshop use this blade provides repeatable panel lines, surface detailing, and precise trimming on body shells and scale parts. Regularly inspect the edge and apply conservative pressure to extend blade life and keep groove depth consistent across passes.
