Very nice work and a great result. I would have loved to see some of the design process too.
I've subscribed and very much look forward to seeing your future work.

Thanks so much. I did 3d print a prototype to test the concept and it worked well so just printed the final version based on the prototype design. So glad the knife worked for each performance without any failures.
