Precision Pocket Scriber

The Starrett 70A is a hardened-steel pocket scriber designed for accurate layout work. Its straight point and polished finish resist corrosion while delivering clean, precise lines on metal or other materials. A knurled chuck on the handle provides a secure grip and allows quick tip changes to suit different marking needs. The compact 6-inch length fits easily in a pocket or tool pouch.

Machinists and Maintenance Technicians

This tool suits professionals who need a reliable, replaceable-tip scriber for daily layout tasks. It is not intended for heavy centre-punching or for users who require a fixed, non-adjustable point. Buyers who want a carbide-tipped model or a larger scriber for deep scoring should look at other options.

Replaceable Straight Point

The defining feature is the knurled chuck that accepts interchangeable tips, letting you swap the straight point for different profiles without buying a new tool. This flexibility determines whether the 70A matches your marking workflow.

The tool includes the handle with knurled chuck, a straight hardened steel point and an insert that accepts various tip sizes; replacement tips of different profiles are sold separately.

The standard 70A model with its 6 in overall length, straight point and polished finish is the single version offered and suits general scribing tasks.
