Knife with mustard packet before the etching.
We’ve been playing with the etching of metals with our laser cutter at Workshop 88. One of our members discovered a mustard-etching method and tested it out last night during the weekly open house.

Reapplying mustard between passes.

Finished etched knife after cleaning.
The results are pretty great for a first attempt! Expect more detail to come in future posts – but if you want to know more, please come to our open house meetings every Thursday night!
