The ISC Etching Pen is an essential piece of equipment for jewelers, glaziers, mechanics, and craft enthusiasts who require high-precision marking on non-porous surfaces. This tool utilizes a micro-sharp tip, typically made from exceptionally hard Tungsten Carbide, to scratch or “scribe” a permanent line into materials that markers cannot easily mark.
This pen-style tool offers superior control compared to larger cutting tools. It is specifically used for:
- Marking: Writing permanent serial numbers, identification codes, or signature marks onto metal tools or equipment.
- Scribing/Scoring: Creating a precise, shallow groove on the surface of glass or ceramic tile. This groove guides the subsequent break, ensuring a clean, straight edge.
The “Combo” aspect of the name suggests it is often bundled with a larger tool (like a traditional glass cutter or the 2-in-1 tool you showed previously) for a complete cutting and finishing set.
Key Features:
- Tungsten Carbide Tip: Provides exceptional hardness and retains a sharp point for fine scribing.
- Permanent Marking: Ideal for engraving permanent identification on tools, metal, and plastic.
- Precision Scribing: Used to score glass, ceramics, and tiles for clean manual breaks.
- Ergonomic Design: Pen-style body (often knurled for grip, as seen in the image) provides comfort and writing-like control.
