At 0.1 mm, Tamiya 74135 is the finest tungsten carbide blade in his scribing range for plastic models. It gives the modeller a particularly narrow option when adding recessed detail or restoring an existing line, including aircraft panel work. The blade is supplied without a handle and is recommended for the separately sold Item 74139 Engraving Blade Holder.
Pack contents: one precision-ground engraving blade
Shank diameter: 2 mm
The included case accepts up to ten blades; a blue thickness identifier can be cut from the backing card and placed inside

Notes · Q & A
What blade shape should I use for miniatures — #10 or #11?+
The #11 pointed blade is the default for trimming mould lines and fine cuts. The curved #10 belly suits slicing and scraping over larger areas. Most modellers keep an #11 in the handle and swap shapes as the job needs.
When should I change a blade?+
The moment it drags, tears plastic instead of slicing, or needs pressure to start a cut. A blunt blade slips and causes most knife injuries, and blades are far cheaper than the finger you save. Snap old ones into a sealed tin.
What's a razor saw for that a knife can't do?+
A razor saw removes thick sprue gates, cuts resin blocks and separates parts too chunky to slice cleanly. Its fine kerf leaves a flat face with minimal material loss, where a knife would slip or wander on a thick section.
How do I scrape mould lines rather than cut them?+
Hold the blade at 90 degrees to the surface and draw it backwards, shaving the raised line in light passes. Scraping controls depth far better than cutting and leaves a smooth surface that needs little or no sanding.
