So I decided to give the steel engrave thing a try for one of the professors here looking to make a gift. I went with the paper towel, damp with water, method because it looked the best from what I’ve seen here. 1/4 way through, it was dry and no longer covering the knife. But it was still working, so I let it continue. This is the result:
Now, this was a highly magnetic and expensive knife. Results may vary.
Setting used: 150 zooms, full power (pro-45w). Knife knife was fixtured to hold blade flat and level. Distance from tray .434
