I made it on a 10cm Victorinox office knife.
Any additional items needed?
Nicely done, care to share your settings for others?
I do not use any other products on the blade on this try.
For fixing the blade during the process I use blu tack.
Params 10w laser at 80% at normal speed
I will do a other try with mos2-fett and check if the engraving is darker.
