Tamiya added 74162 to its blade range for a specific middle-width line: 0.25 mm, between the neighbouring 0.2 and 0.3 mm sizes. The hooked cemented-carbide tip is intended for scribing car models, where that intermediate cut gives another option for panel and body detail. An orange band on the shank identifies this thickness within Tamiya's colour-key system; it is a size marker, not the blade's colour.
The 2 mm shank is made for the 74139 Engraving Blade Holder.
One blade is supplied; its case can store up to ten engraving blades.
Introduced in 2021, three years after the original range.

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.
