M8 Engrave It Tool
|This handy little cheap and cheerful hand tool (approx 7"/18cm long) is fitted with a vibrating hard point that will engrave on most surfaces. It works very well on the plastic scratch on/off labels (SCR1 or SCR2 - Ceanothus Burkwoodii) but also cuts through the anodised layer on our Aluminium labels. Requires 2 x AA batteries.
Also very useful for permanently naming household equipment like mobile phones.
