This is a notice of intent to manufacture...
Of late, liner locks have taken a good bit of heat. They tend to fail under certain uses and I think I may have a solution.
Problem # 1
Liners fail under use because your finger disengages the lock and releases it while in use. This is more a design flaw than the lock actually failing. The locking mechanism is too close to the outside frame of the knife and therefor is inherently dangerous.
Solution.....
Make the lock recessed inside the frame of the knife. Most liners are pancaked between the two halves of the knifes frame. This not only makes the liner too close to the outside but in most cases is not visually or aesthetically appealing.
But how can you push the liner down to release the blade?
This image shows the lock disengaged.
This image shows the lock engaged.
Put a tit on the liner like the one shown in the image above. You simply push on the tit and it releases the blade from the lock and it further allows you to push the liner into the recessed area of the frame.
Problem # 2
Liners disengage under pressure.
Part of the reason is that the liner is engaging the back of the blade and not the blade itself. If you bend the liner and make it fit into a recessed area of the blade it will hold stedfast. The groove cut out of the blade will be the same angle and shape of the bent liner. Therefor pressure on this part would not release the blade and it would not "slip" out of the socket.
But Mike, a bend in the liner would make that part weak and it would bend even further under pressure.
Yes it will bend under pressure but the lock would not fail. The bend would push against the inside frame of the knife but it would still keep the blade from closing.
How much pressure would it take?
That is the better question and that would depend on the material used to make the liner. Titanium would be a great choice as it can be bent to a specific angle and retain it's inherent high strength.
The cool thing is the lock would actually engage the blade.
Imagine trying to keep a door open by putting a wedge between the door and the frame. That is basically what a liner lock does. The door (Blade) gives you a lot of leverage with the wedge so far back. Now take the wedge and have it placed under the door about 20% of the way up and you have a much better way of keeping the door open.
Why make a new style liner lock?
Simple, the fact is they are easy to produce, easy to demonstrate and very easy for the end user to learn. Plus the fact that the industry and the public already accepts liner locks, there would be no real education process like other locks which are on the market and those which are coming to market.
So whadayathink?
