Hi there and happy Friday.

After some consideration, I would like to share some thoughts on the Buck liner lock.

This video shows a very nice Buck 293 Inertia with a perfect lockup but sideways force on the blade disengages the lock nearly completely.

This video shows a very nice Buck 290 Rush with a liner lock that does not fully engage.

While the Buck liner lock is strong and holds the blade open tightly when fully engaged, there is, according to my observation, a certain amount of precision required.

Please post your comments on this.
 
the sideways torque on blade push is a bit odd tasking for folder use. I get and see what your saying, just dont think I'd use a folder where I had to apply that much pressure sideways while cutting.

liner locks have their flaws, they arent for everyone. I dont mind them as long as when I put pressure on the spine towards close and the lock bar doesnt slip towards open. they are safe enough for my uses.

why didnt you put the side pressure on the other knife with the early lockup.....did you and it failed or it wouldnt flex enough to fail? asking cause I dont know.

this part isnt for you but someone who might Google down the road and read my post.....when applying back pressure dont have fingers in the way as if the lock slips open you'll get cut and badly.

Was illustrating how the liner lock can not fully engage. The lock will fail, just hard to do with one hand. Is a matter of angle. It has slipped off under pressure.
 
I have a Buck Sekiden two-blade liner lock in my pocket right now, so I took it out and applied a reasonable amount of force on the blade in four directions without any indication that the lock might fail. Bear in mind that it's an old knife that I use for work, so it's by no means pristine. That being said, I much prefer a back lock.

elaborate please. I'm following but not getting it completely what you're saying. thanks.

I think a well done liner lock might be the finest lock but engagement needs to be not a question. Perhaps a different implementation.

My observation, flex the handle of a knife that utilizes a liner lock and I would imagine it will move the liner lock one way or the other depending on which direction your forcing it. Early lock up is just early lock up. Some break in time would typically end up with a knife with perfect lock up.

The angle of engagement must be over center with the line perpendicular with the surface the lock engages with. Or it can slip off under pressure. You can try this with any liner lock. Just disengage the lock until it looks like my Rush in the video. And apply pressure.

Wear cut proof level 5 gloves...

unless its a heavy use liner lock with titanium scales. It would be tough to flex the handle. The 293 line is a normal use knife. I would not use that model for much of anything that might be considered heavy use.

There is a video about some guy disappointed in his Bantam knife. He used it in heavy duty use applications and it failed. So he blasts this on U Tube. he gets absolutely hammered in his reply's from viewers about he should of bought a knife built for what he was using it for. Instead of a 20 dollar plastic handled bantam.
 
The Linerlock is a locking mechanism for folding pocket knives. A Linerlock is a folding knife with a side-spring lock that can be opened and closed with one hand without repositioning the knife in the hand. The lock is self-adjusting for wear. Self adjusting is key word here.

Liner lock will Break in over use. Leaving you with a perfect operating lock.

IMO, there are plastics and then there are plastics. Some are flexible. Others are stiff. I don't think the old Bucklites had as much of an issue compared to the Bucklite Max and Bantam folders. I'm hoping the newer LTs are stiffer, more like the older Bucklites. IMO, Buck shouldn't be making folders that open up and get sloppy quickly. IMO, it's not an obvious matter of cost. It's about good material choice, good design and good manufacturing. There are $15 knives out there (think the Savoie region of France) that will take a lot more hard use without developing play than some Bucks. IMO, the Ecolites were on a good path with their partial metal liners.
 
Nice title to the thread. Im sure Buck appreciates it also. If I remember right your the Pit Bull slayer with your Marksman.

Below is a small piece of what Buck does for alot of people. Knocking their liner lock which is no different than any other liner lock is a shame. People will read your post and second guess a purchase.
So if you could check out the positive then the negative isnt so big.

--May 2017--CJ BUCK TO EMCEE AKTI FUNDRAISER AT BLADE SHOW
CJ Buck to Emcee AKTI's Fundraiser at Blade Show
Event will feature custom knives and limited editions from custom knife makers

Post Falls, ID-May 31, 2017 - CJ Buck, CEO of Buck Knives, will serve as master of ceremonies at the American Knife & Tool Institute (AKTI) "Free to Carry" Fundraising Event. Buck also serves as President of AKTI, as well as CEO and Chairman of Buck Knives.

Held June 2nd in Atlanta, Georgia at the Blade Show, the event includes handmade knives and limited editions from custom knifemakers and brands.

"The American Knife & Tool Institute quietly and diligently works for everyone in the knife community promoting knives as essential, valuable tools, working with legislators at the state and the federal level to clarify knife laws, and providing valuable educational information," said CJ Buck, AKTI President. "We cannot thank these makers enough for their tremendous support."

The "Free to Carry" fundraising event gives custom knifemakers the opportunity to give back to the charity of their choice. 50% of proceeds will go to the charity they assign, while the other 50% will go to AKTI to fund legislative and educational efforts.

CEO CJ Buck said, "Karen is tireless and creative in orchestrating the contribution campaigns. She also adds credibility to whomever she is campaigning for."

This shines through in her Employee Campaign efforts. Cook feels United Way of Kootenai County does a great job of identifying community needs and supporting programs that address those needs. Last year, Buck Knives raised $5,700, and a total of $35,738 over Cook's 10 years as campaign coordinator for the organization.

"One of the things I really like about our rural community is the sense of connectedness you have with the people around you," Buck said. "The help United Way of Kootenai County provides in aligning resources with needs within our community really helps people feel confident that a gift they make, to United Way or another charity will be used with great care and respect.

"Buck Knives participates in a number of programs to support the community and our employees," said Cook. "We donate to the Post Falls Food Bank and have supported the Kroc Thanksgiving dinner drive. We also donate knives and other Buck products to local and national nonprofit organization fundraisers and serve as a raffle ticket outlet for them.

Buck doesn't set out to make knives that get sloppy quickly. it just happens. Ford or Chevy don't set out to make vehicles that break down either but it happens. Planes shouldn't crash, Ammo should always fire, Tires shouldn't blow, trains shouldn't derail. etc.

There are things that happen that are just plain going to happen no matter how hard their are designed not to.

Back lock, definitely a better choice for harder tasks.
 
Exactly. I'm not quite sure the reasoning behind this thread. I'm sure this could be said about any liner lock if someone was to misuse it.
I prefer an early lock up. It will break in and settle in a spot and stay there for time.

Warning!!! Warning!!!! Do NOT be a Dumbass and try to operate a KNIFE at the same time!!!!
