This can be arranged for orders of 10 or more tools through a local laser etching service at an extra cost. For quantities below that we recommend seeking your own local laser etching or engraving service. For those in the east of Melbourne we recommend Bayswater Sign and Badge https://signandbadge.com.au/ Most areas have similar services such as trophy companies who can help.
Due to their construction, engraving and laser etching will not void the warranty or longevity of the tools. On the full sized tools, engraving will remove the zinc coating. This may cause some corrosion to occur locally at the engraving but should not cause long term damage.
