Hey everyone,
I thought I'd share with you my findinds pertaining to laser engraving. I started with a 5W output 455 nm, and I managed to get sub-par results by coating the blade beforehand (sharpie, mustard, painter's tape...).
I recently acquired a USD 400ish 2W 1064nm IR head, and the results are amazing. I can engrave knife blades with the sharpening angle or with their owner's name. I can also put a straight mark on a chisel right where I want. It can also mark plastics (preferably light or dark as the result is kind of greyish), so handles can be marked too.
It might be a nice addition to a premium sharpener's toolset. Mine is an open-frame one, so quite bulky, but there are also portable versions that will engrave up to 70x70 mm.
Cheers,
Nick.
