It’s perfectly reasonable to want a very secure locking mechanism like the triad. Some people work with their knives, some people would like to be confident that their folder won’t fold if stabbed into something.
I’ve had a liner lock knife fail because I was working in tight quarters and managed to hit the spine on something while I was maneuvering.
So I politely suggest you not question what a newer member here is doing with their folding knife that warrants worrying about lock strength.
I worked with all my knives, including friction folders and slipjoints, in industrial jobs and construction; I didn't work in an office. (I'm not saying those here that use their knives at a job only work in an office, or only use them to open mail and boxes, or to break down boxes, or to slice an apple, or something.)
The backspring on a knife was invented in the 1500's. Prior to that, people used either a fixed blade, or if they had a folding knife, it was a friction folder. The oldest known friction folder in existence (found so far) dates from the Roman Empire, by the way.
The "peasant knife" or "penny knife", a (usually a low cost) friction folder with no lock or backspring, and the slipjoint have been used by our ancestors for hundreds of years, perhaps as much as a thousand plus years, and they used them a heck of a lot "harder" than most folk would dream of using their knives today.
Our ancestors weren't cutting or amputating their fingers using a non-locking blade folding knife, because the blade suddenly closed on them.
Today, in most of Europe, all of the British Isles, Australia, and other locations, locking blades are illegal, and fixed blades are highly regulated, if not banned unless at a job site and the knife is required for the job. (such as a chef.)
Those folks are not filling the ER because they are severely cutting or removing their fingers because they are restricted to a friction folder or slipjoint.
When I was a youngling, the backlock, frame lock, and modern liner lock (a few knives used an early form of the liner lock beginning in the 1800's. The slipjoint was far more popular) had not been invented yet. I've noticed over the years that a locking blade has caused quite a few folk to get careless.
Like a "safety" on a firearm, no blade lock should be trusted. Like the "safety" on a firearm, any blade lock can fail.
A locking blade does not make a knife "safer". IMHO, quite the opposite, since it "encourages" people to be careless and to depend on the lock to prevent injury. Remember: any lock can and has failed. No blade lock is going to make a folding knife as strong as one that doesn't fold.
