There’s some information on here about engraving steel on knives, tools, etc, but I haven’t found much that worked for me personally. I’ve been looking at doing knives, firearms part, etc for a number of people and have had very mixed results. Today I engraved a knife that was custom made for me by a close friend, Ryan Turney of Ryan Turney Knives in Amarillo Texas.
In the first attempt, settings were as follows:
As you can see, it isn’t as defined as we would all like to see:
In the second attempt, I slowed the speed to 100, and left the other settings the same as before. As you can see, it’s almost perfect! It’s a dark engrave, about .5mm deep and very clean. All in all, an excellent result:
This echos what I’ve seen in my other attempts. If you want to do hardened steel projects and get a deep, dark, clean engrave, my minimum recommended settings are as follows:
Be aware that ultra-small designs tend to “meld” together with these settings, even on hard steel. You may also have this effect on larger designs if you slow it down too much, I think it tends to burn the metal on the surface too much (i.e. 50 speed or slower). If I find a way to get cleaner micro-designs on hard steel, I’ll update this thread.
Please share your thoughts and your experience!
