USTAR 91800 Scribing Needle Pen – Precision Panel Line Tool for Gundam Models

Scribe Cleaner Lines. Build Better Models.

Panel lining is where good builds become great ones — but a dull tip, a slipping grip, or a tool that skips across the surface can ruin hours of work in seconds. The USTAR 91800 Scribing Needle Pen is engineered for modelers who refuse to compromise. A razor-sharp conical needle tip, a precision-weighted body, and an anti-slip rubber sleeve give you the tactile control to cut crisp, consistent lines into plastic, resin, and soft alloy — every single time.

Frequently Asked Questions

Q: What is the tip shape of the USTAR 91800?

A: The 91800 features a conical (round cone) needle tip. This geometry is ideal for scribing curved panel lines and engraving fine detail without the tip catching or skipping on the surface.

Q: What materials can I scribe with this tool?

A: It works on polystyrene plastic (standard Gundam runners), ABS, resin, soft alloy, and most composite model kit materials. It is not designed for hardened steel or glass.

Q: Why is a whetstone included?

A: Scribing needles dull with use, especially on harder materials. The included whetstone lets you restore the tip’s sharpness in seconds, saving you the cost and wait of ordering a replacement needle.

Q: How does the anti-slip sleeve help?

A: The rubber sleeve increases grip friction and cushions your fingers during extended scribing sessions, reducing hand fatigue and giving you more consistent pressure control — critical for clean, even lines.

Q: Is this compatible with USTAR replacement needles?

A: Yes. The 91800 body accepts standard USTAR replacement needle tips, so you can swap to a different tip profile (e.g., chisel or blade) as your project requires.

Q: How is this different from a basic scribing tool?

A: The combination of a precision-ground conical tip, balanced pen body, anti-slip grip, and an included whetstone makes the 91800 a complete scribing system — not just a needle glued into a handle. The result is more control, less slipping, and a longer-lasting tool.
