Everyone's folders are, either on the way, in possession or going to be hand-delivered. Although I haven't used mine yet, I found a fitting custom "pancake"-styled sheath for it and I'm ready-to-rock! Thanks for "blades", S!
Stay Sharp,

Captain Chris, thank you very much for great help! I very grateful to you

I hope you all enjoy the knives when you receive them!

An old book from 1771 by M. Jean-Jacques Perret helped me a lot. It is in the public domain. Very interesting from the point of view of the development of the knife industry. There are wonderful illustrations at the end of the book

The handle is already ready, the mechanism has a backspring integrated into the rocker, like on the original R1306 1920's
