K, It was great meeting you guys at BLADE and I look forward to following your work further. I think your retention design has really "knocked it out of the park". I can't believ no one else had thought of this before you, but it was dang smart of you to submit it for patent. Congrats on the "provisional" and good luck on locking it in permanently. One of these days I would love to make it over to visit the shop and see how you guys do it.
