Any Spyderco in framelock?

This video might help you out if you haven't tried closing your knife using these different methods. I personally close my lockbacks using the second method shown, with the index finger in the opening hole. Very natural for Endura-sized knives.

Just to clear the air
Thanks for clarifying...which did nothing to eliminate the purely subjective nature of your claim that the integral compression lock (that is the correct term) is in terms of function completely different from a Chris Reeve style integral frame lock. Functionally the locks are basically the same regardless of the differences in force directions and distances involved during lock-up and as a result of any lock stresses during use.

No need to clear the air and no hornets nest was stirred but this topic has come up before, and my off-hand remark was result of the assumption that people knew the discussion as the ATR is not exactly a new model.

However, the following is in my opinion quite serious: There is absolutely NOTHING subjective to my claim that the two lock types are completely different. If the direction of the forces are different the lock failure mechanism is completely different the reliability is completely different and the underlying mechanism is completely different. These differences are patentable and patented and the claim that they are even remotely the same is as far off the mark as saying that a magnetic lock is the same as a conventional lock, just because you insert a key into both and both are used to lock something up. It is simply not true - the mechanism is different. Anyone claiming different has probably has never held an ATR and seen the lock only on pictures. As to the statement that only the direction of force is different and that is not enough to make a significant difference: the difference between a cable bridge and a pylon bridge is mainly in the direction of force!

Further, a liner lock and a frame lock are indeed essentially the same. There is no difference in the working mechanism between the two, and yet they are referred to as frame and liner lock respectively. Considering the significant differences in the working principle between the integral compression and the CR integral lock, it seems only prudent to distinguish between those two verbally as well.

Finally, Spyderco has, unlike other companies in the field, a spotless record of giving credit where credit is due. All Chris Reeve style integral locks on their knives are described exactly as such. Again, if the ATR had a type of CR style integral lock which we have come to refer to as frame lock, it would mean a violation of the attribution of credit to Chris Reeve. A very important point from a legal point of view as well as from the point of basic decency.
 
While being under the shower, I though I should amend my post: Of course, going by the strict meaning of the word, the integral compression lock is a frame lock, since the lock is in the frame, and a compression lock is a liner lock because the lock is in the liner. The problem with this though is, that with the term "frame lock" we have come to associate a particular type of frame lock, the CR style integral lock to be precise and with the term "liner lock" a Walker style liner lock. And the usage of frame lock for a CR style integral is so common, that "frame lock" isn't really understood ambiguously.
 
HoB,
Nicely put! Hope you cleared up your headache while you had it under the shower... :)

I suppose the difference between a CR framelock and a Compression framelock might be subtle to a person who has never handled both. However, if one understands much about physics and mechanics, the differences are much more apparent. Especially after one sees both mechanisms in person.
