Thank you

. Just some of my early work.
They're not assisted, they're entirely manual. There aren't any springs involved in the opening, just a sudden burst of thumb pressure on the thumb studs.
I don't have any videos, or even photos of the process, I did the work on these knives back in 2014 if I recall correctly. I wasn't making videos of anything back then. I don't make process videos of my work now either. The knife work is enough work all by itself without trying to film it (camera angles, lighting, etc, etc). Making videos is not in my skill-set.
The one-hand closing mechanism is a stainless steel wrap-around thumb-press I made and attached directly to the head of the lock.
