Fine scribing for RC model detail

Benefits of the 0.3mm cutting edge

A 0.3mm blade gives steady control when laying down narrow grooves or refining mould lines. The GSI-GT65 balances a keen cutting edge with sturdy construction so you can work fine details without frequent blade wobble or breakage.

Practical uses in scale modelling

This chisel suits a range of scale tasks from aircraft panel lines to fine detailing on plastic car bodies and armour. The ergonomics let you hold the tool comfortably for longer runs of scribing, reducing hand fatigue during detailed sessions.
