Paraclete: The Holy Spirit as advocate or counselor (John 14:16, 26).
I designed this knife, in part, back in 2011. It had originally been set up to be a friction folder and much smaller. But what’s the fun in that?!
A few months ago, I decided that I would revisit the drawings and make a frame lock out of them. So off to the computer to start playing with a wicked-looking folder that was a complete departure from what I have been doing for the last 5 years.
One thing that really helped me with the design of this knife is that I spent some time down at NASA’s JPL (Jet Propulsion Lab) talking advanced metallurgy and machining with some of the greatest minds I have ever had the pleasure to meet. When I was speaking to them, I was working through some problems I have run into as a knife maker over the last 13 years – things like dirt and grime buildup, friction, and weight.
So I picked their brains for all I was worth, and came home and set about testing new theories in the practical application of knife making.I got the inspiration for my new lock, “The 270 Lock!”
This isn’t a complete departure from the traditional liner/frame/leaf lock that was invented by Michael Walker, but it IS a complete departure from how that lock engages the lockface of the blade!
The 270 lock engages 270 degrees of the lockface.
Traditionally, only .06-.100 of the lockbar face contacts the lockface of the blade. Any more contact and the lock will stick very badly or it will have lock rock (movement of the blade while the lock is engaged). So how did I avoid those problems with this lock? Geometry!!! And, of course, lots of machinery. Maybe a hammer…
All kidding aside -- the lockface of the blade has multiple angles of contact and higher and lower pressure points of contact as well… Let me break it down for you:
- The Main lock face (front tip of the lockbar insert) contacts at a moderate angle with high pressure
- The Lower lock face (face closest to the outside profile) contacts at a moderate angle and high pressure
- The Top lock face (closest to the pivot) contacts at a low angle and low pressure
The reason behind the different angles and pressure is to make sure that the lock will push the blade against the stop pin and not allow lock rock, and to avoid the lock sticking by not flexing and giving.
The only downside to this lock is that it requires a great deal of care in tolerance and contact. Most of the surfaces of this lock require a +-.0007 tolerance!
The overall appearance of the Paraclete simply can’t be ignored!
I wanted to design something totally new for me – a much more complicated knife than I had ever attempted before!
Recurves are a pain to grind, bronze bearings are difficult to set up properly, the 270 lock is… Well just read the above to figure that out! So I think my goal has been met… and now it’s on to the next design!
I really hope you like this knife! It exceeded my expectations, and I hope it exceeds yours too!!
