There's a local company that offers custom laser etching. Has anyone ever tried inputting a custom design on their straight (either the blade, scales or both)?
I use a laser engraver at my work, and the problem with engraving steel is not that steel is hard. The problem is that steel reflects. Anything that reflects is problematic, and in most cases may damage the engraver if the laser is at full power.
The most popular thing to do with stainless steel is to do what is called laser acid etching. Basically, you place tape over the section that is going to be etched, then you use the laser to cut away the tape in the shape of the engraving. Then you use acid to etch the exposed parts of the steel. Once the acid is cleaned off, you pull off the tape.
I don't recommend this process with anything you care about, as there are plenty of slips between the cup and the lip.
You can always engrave stainless steel with a diamond drag rotary engraver. (Like the engraver they use at Things Remembered).
The person that is doing my scales was going to try and laser engrave the blade, but had never worked with high carbon steel (The blade is a J. R. Torrey) and had too many problems during the setup.
I have 2 sets of scales being laser carved and inlaid with my monogram.
