Surface: Anodised titanium Engraving: Serial number I have an ultra-light knife with an anodised titanium handle and I am looking for something to make the serial number in the handle stand out even more. So I'm looking for a kind of wax pen or whatever you call them that are used for firearms etc. to colour the serial number. As a kind of pen/marker/wax that is UV and water resistant and does not smudge. And is not absorbed too quickly and can still be wiped off in time, so that only the deep areas (engraving) remain filled with colour. I don't know if something like this is listed here on Galaxus, as the selection of pens is overwhelming and the names don't always include the area of application. But maybe someone can help me. Thank you.
