Axis locks are fast to deploy with a minimum of practice from the pocket for most right from the start. Good materials throughout and a solid performer in the right hands without question.
The Chinook is a lockback and will take a little more effort to be as fast to deploy for most. Both are as fast or as slow as the other in my hands with the "pop" method I use.
Either leaves the pocket and goes in a straight line to the target immediately for me. There is no faster way to deploy than one which will take a folder from the pocket in a straight line to the target. Everything else is going to be longer in time for deployment.
As the Chinook was designed to "snipe" [ as dirk mentioned earlier ] at incoming limbs using the backcutting technique others have mentioned already, the design incorporates a lock strong enough to handle that particular chore if one so desired in a defensive scenario. The strength was built into the design parameters. Though it may fail, the odds of such ocurring are slim at best.
It was well thought out by a nationally known self defense instructor and made to his specifications by one of the great companies producing folders.
At one time, I bought linerlocks and later, axis locks, due to the speed with which they could be accessed [ all due to lock designs ] and deployed using the "pop" method mentioned elsewhere previously.
Linerlocks have failed at the worst of times and I can not bring myself to rely on them for defensive needs. Axis locks are certainly strong enough to withstand what may be required but I am not enamored with the locking mechanisms positioning as I personally feel it could be disengaged inadvertently during a dynamic encounter.
I have in the past year gone to carrying lockback type folders as in the Chinooks, the new Persians, Blade-tech folding kerambits, etc as I feel the strength and ergonomics of the lock during an encounter are at least as important as speed of deployment.
The Chinook 1 took a long time to "tweek" so that it would fly open from the pocket with inertial openings or flicking but was never as fast as it could be in my experience. The Chinook 11 does not suffer that same liability and was redisigned with numerous upgraded features. The Chinook 11 received "pop"ed from the first opening with as much ease as any axis lock or linerlock for me. The speed of deployment no longer being a limiting factor in choice of a defensive carry folder.
The Chinook 1 and 11 have a much stronger blade by design. IMO, the blade of the 806 will be more prone to damage or breakage over the Chinooks but thats not to say they are fragile, just less strong as the Chinooks.
I think either in the right hands will create much tissue damage if used by one who has some ability and experience with tactics/techniques and that both have good ergonomics for blade manipulation drills.
Each person will/should develop, through their own experiences, some way to deploy a folder from the pocket with some practice to gain the speed necessary to respond to an immediate threat presented.
WadeF can open his axis locked knife faster than he can deploy the chinook with the pop. Thats just his body and experience with the two knives. Others may be able to deploy the chinook or another folder faster with an inertial opening. It will certainly depend on each individuals preferences, training, practice time in deploying, and other variables. One is not better than another as we each are individuals with certain restrictions based on hand size, dexterity, experience, longevity in carrying a defensive folder, etc, etc.
As to Wades drawing against a Chinook owner any day, I'll take that challenge thrown out to the forum at the first opportunity we can meet up. We'll videotape the results of several side by side deployments. Then I'll hand him the Chinook and I'll take the 806 and we'll try again. The results should be the same [ though he mentions going against one using the spydie drop deployment, I'll use the Brownie Pop instead ].
It's the users experience and practice, not the blade or locks design that determines which work best for fast openings [ though admittedly certain folders designs are more conducive to others where this subject is concerned ].
We should not get stuck in the mindset that we carry a certain knife because it can be deployed faster than another as I was at one time myself. The real issue where folders are concerned for possible personal defense are the locks strength, ergonomics/handling, materials used in it's construction.
As I have 11+ years of deploying many different folding locks designs behind me using the Pop, the choices are not so much which can be made to deploy more easily [ they all can be deployed fast enough ] but which has the potential to withstand the most abuse by design and materials if the SHTF and I had to absolutely defend my life in a real world encoutner.
In this particular post, that choice would be the Chinook 1 or 11 for me. For no other reason than it is the stronger design all around and does not suffer in deployment speed for me over the other.
WillP: You actually practice offensive moves against another with a knife with hardly any or no defensive training? As the GG's, we need to have defensive tactics to defend long before we need offensive knife skills. BG initiate and are offensive, us GG's are, at least initially, in a defensive posture.
You have never heard of Jim Keating? Do a search, his background and experience helped create and bring to market the Chinooks. There are few who surpass his knowledge and training with blades of all configuraions. Those facts are rarely, if ever, disputed for a reason.
