I have been thinking that each year I will probably update my mark slightly, and it will be a way that my progression as a maker can be charted. We already know my 2020 maker's mark, and now this will be my 2021 mark, and so on.
That being said, anyone who still has an unsigned knife from me is welcome to send it back for a mark. Knives I made in 2020 (or earlier) will get my 2020 mark. If I were further ahead financially I would not ask anything for this, but for now I will ask for return shipping and a small fee for stencil consumption, probably $10 per knife. And I will be sure to give the knife the spa treatment too, including sharpening and I'd put a little something extra in the package as a thank you.
