Marking what you make is a no brainer. It's even more fun if it involves open flame.

You'd usually run this through a CNC but I don't have one. Given I have a lot of curves in my mark, I opted for aluminum to dremel its out and inlines. And since I was at it, I made three different sizes.

+Finncrafted showed pretty much the same approach on steel, his straight lines involved a cutoff disc for the dremel tool.
