Starmate lock design question

[Ted]

Hi,

I found the following thing very smart on the design of my Military. I don't really know how to describe it, but it's the way the back of the blade was shaped to lock with the liner. I included a (very bad quality) picture of my Millie, but I hope it makes it clear.

It's the yellow line which on most knives is on a 90 degr. edge with the blade (for ex. the cricket), but not on the Military, which I think makes a much better lock with no play on the blade.



Is this done the same way on the <img src="spyder.gif" width=15 height=15 align=middle border=0> Starmate? (or other Spydies)



Thanks,

Ted

This feature is also present at the compression lock (at least at the Vesuvius). It provides a constant pressure so the blade won't wiggle.

That's commonly referred to as an arc ramp. It is definitely a huge improvement over the last evolution of liner locks(which is the way most companies still produce them).

The kicker that puts Spyderco linerlocks way ahead of anyone else is the eccentric pivot, allowing the liner to be readjusted back to the beginning of the ramp, effectively extending it's life beyond what most people will ever need.
And all the benefits of the arc-ramp and eccentric pivot transfer over to the compression lock mech. as well. Very smart.

Ted - My Starmate has the arc ramp. And, btw, I think your photo is actually pretty good, it certainly shows very clearly what you are referring to.

If you read bob terzuola's excellent book the tactical folding knife, He goes into great detail about the function and development of what he calls the&quot;fail safe liner lock&quot; it's a bit involved, but the 16 bucks is worth it to buy the book, anyway. that exact bevel has at least 2 chapters dedicated to it.

Dijos,

I'd sure like to find that book, who is it published by?

Jeff/1911.
