    You also want your liner lock to go half or cross past the center. If the liner only 1/3 into the blade it can jump back aka unlock from pressure on the blade. Spyderco fixed the lock back issue a while ago by concaving the lock where you press down on it.

    Benchmade axis locks will easily disengage from punyo strikes, making them fundamentally unsuited for a defensive knife. The Manix CBBL seems resistant to this behavior due to the much higher disengagement force requirement.
    The mid back locks on Spyderco's Seki models can definitely wear out from inertial deployment, but Spyderco's Golden back lock has a deeper lock well and lock bar engagement depth, and is immune to this problem.
    Compression locks do fine with static loads, but they will disengage from spine strikes against hard surfaces.
    Frame locks are extremely vulnerable to self-interference. It takes very little pressure on the lockbar to prevent deployment. This can be trained around, but as a defensive lock they are less than ideal. Liner locks do not have this issue, and should not be grouped together when considering them for defensive applications.
    In my experience, the most reliable locks are the mid back lock as implemented on the Spyderco Native and Native Chief, the Manix CBBL, the Millie liner lock, and the triad lock. I would definitely not carry an axis lock for defensive purposes, and I think the compression lock and Seki back lock are questionable. Frame locks and liner locks should be tested on a case-by-case basis, as there is a wide range of reliability and failure potentials among various brands and models.

      I'm not really a martial / defensive arts expert, but I think in most self defense scenarios people won't and more importantly shouldn't use a punyo style of strike.
      Benchmade knives for the most part are lightweight, with FRN / Grivory handles, which wouldn't lend much weight to a strike like that.

    Good video, welcome back. I prefer the ball bearing, compression, and tri-ad locks for my carry knives. All very strong. I do rotate in a few R.E.K.A.T. knives, but I can't recall the name of that locking mechanism. It's also quite strong.

    Basically the Tri Ad Lock is a back lock but it is like the Hercules of back loxks. I have experienced a lock back fail with the lock release at the end of the handle by cutting with it in the blade up position pull towards myself and tne lock must have got squeezed because my thumb got cut with a Buck 110.
    The Tri Ad Lock being in the center make a word of difference and the stop pin on a Tri Ad lock back I believe add to the lock life tremendously , I have never heard of one failing although there may be a few but I just have not heard of them.
    It would be good to hear your thoughts on the Tri Ad Lock.

    I personally am absolutely SICK axis style locks. At least ones with omega springs (so most of them). Its no secret that omega springs have a tendency to break and that's my big problem with them. The only 2 I can think of that have gotten it right are the Benchmade Anthem and the Spyderco Manix 2. And yes I know they're not exactly the same but they're close enough for the comparison to work. They both have a coil spring rather than omegas which typically work better and longer. And at this point with well made button locks being able to be found in the budget range I think it's just about time to either adapt the axis style lock to a coil spring or for them to just kinda fall away. I know it's a hot take but I mean come on...would you rather deal with springs breaking and having to replace them or have a better system with the same basic function? I know what I'm picking.

      I don't have any hands-on experience with the Emerson CQC7, but here are my thoughts (for what they are worth) just looking at the pictures. If you like knives with the Emerson wave, then you are getting a knife from the original source of waves. Emerson has a good reputation for making good knives. It looks like the CQC7 is a liner lock, which I've never had an issue with, but I would prefer the ball mechanism in the Manix 2. I'm not a fan of the American tanto style tip the CQC7 has. It provides a very strong tip but it won't penetrate as well as the more acute tip of the Manix 2. The ability for the knife to penetrate well is more important to me than extra reinforcement of the tip. Personally I would select the Manix 2, but if you like the CQC7 it looks like it can get the job done as well.

    The McHenry-Williams lock, aka Axis Lock, is by far not reserved for Benchmade knives. The patent has ran out and allmost all chinese companies use the Axis Lock by now for any of their knives. Like Ganzo, DuraTech and a plethora of others.
    The Axis Lock is by far the best lock. Ganzo for example has improved the Axis Lock to an "auto adjustable axis lock". It has converted the Axis Lock into an Tri-Ad Lock which is as well auto adjustable. Ganzos axis lock has a few milimeters of room foreward when fully opened the blade and the blade has more room to allow for more foreward movement of the axis bar. As things eventually wear out there is more room for the axis bar to creep foreward onto the back of the blade. As well the cut outs of the handle where the axis bar is riding in is turned down geometrically just a tad in order to force an downward position while having left plenty of foreward room to make up of eventually wear out situations over decades. I have not seen any wear at all on my Ganzo 729 which is an Paramilitary 2 hommage but with axis lock.
    I bet Ganzo has made an improved Axis Lock which beats all other locking systems hands down. I would not be surprised if the McHenry-Williams lock would become the standard over time allways if it can beat the cheapness to manufacture of the liner lock.
    Liner locks chew through over time. In 1 to 3 years I have seen an frame lock chew through to the other side causing blade wobble and an Gerber EAB I used for 1 year chew through as well it's liner lock and developed blade wobble up and down.
    Button locks are prone to develop blade wobble as well since tolerances have to be very tight on that type of lock in order to work propperly.
    Do not look further, just buy a knife with the Axis Lock. Just the axis lock is not very playable and can be stiff often - which is a good thing. Knives are not to play around, open and close in front of your buddies or to kill time but rather only to open if you wanna use it. Knives are not toys to play around open and close endlessly. So an stiff Axis Lock is just fine for everybody.

    How do lockbacks wear out when u have 40 year old buck 110s ....

    • @TheKnifeLifeChannel
      @TheKnifeLifeChannel  2 роки тому

      An important thing to remember is that all knives wear out eventually. It depends upon the use of the blade. My Spyderco's are subjected to some really aggressive openings. Inertial openings are pretty hard on knives. If you practice deploying your defensive blade repeatedly like you should, you will see wear over time. Lockbacks rely on the angle of the tang and the blocking bar matching up correctly. If it wears out, then its easy to overpower the lock. I don't use my Buck knife for the same application, nor do most buck owners. They typically experience a pretty soft two handed opening to perform some task. Nor do I practice deployments with my buck. The lock will still wear out over time from steel rubbing on steel, but it will take a lot longer.
