Abig Etching Needles have a good solid design. They are inexpensive tools recommended particularly for Rhenalon, Astralon and Schappa plates.
The hardened needles are enclosed in a sturdy wooden handle 16cm long. These Abig Etching Needles can be resharpened like a pencil, meaning the whole length of the needle can be used. They are available with various tips.
This tip is a 1.5mm x 45mm round metal point.
