The image is my current EDC, it is close to 30 years old. I cannot remember where or when I first got it. I do like the knife, but it is 100% right-handed. The image above shows how far I can open it one-handed before I have to place my thumb on the blade to finish opening it.
I am looking for a knife that is 100% left-handed, not ambidextrous. Those knives always have some part, typically the blade lock, that most be made for either left or right and right always wins.
I would like something with the same kind of blade, minus the serrations. I hate sharpening this thing because of them.
The handle is decently thick, I would like to stick with something like that. I have a Ken onion knife that has a really thin handle and I do not like it.
I would like to keep it under $150, but for the left blade that is negotiable.
You do want a knife that's ambidextrous, but the root of your problem here lies with looking at liner lockers. You will want practically anything but a liner locking knife, because those are by default designed with the lock on the left when looking down the channel, appropriate for right handed users, because obviously the majority of potential customers are right handed. (I suppose this would also exclude Spyderco's "compression lock," and basically all button lockers.)
There are vanishingly few specifically left handed knives, but there are many with the lock mechanism on both sides. Part of your problem here is also that the manufacturer of your knife elected to put a thumb stud only on one side of the blade, apparently just to be assholes. Better options will have a stud on both sides or some other opening aid.
Almost anything with a back lock or some manner of Axis/crossbar/toggle lock will be unlockable from either side. The blade you have there is a drop point profile which is a pretty popular option. You'll also want something with a reversible clip, which is sometimes a curiously missing feature from knives that would otherwise be suitable for left handed users. Even so it should not be difficult to find something that will fit the bill for you.
I'm going to suggest the Kershaw Iridium just for grinsies, because I think it will work and I don't yet own one so it won't look like I'm shilling my own writeups right out of the gate.
Otherwise, in broadly chronological order (mine, that is), consider:
The SOG Ultra XR
The QSP Penguin Glyde (one of my top picks of 2025)
The Ganzo D727M
Or if you want to get really strange...
The CRKT Daktyl
Or if you want to declare the heck with it with the lock entirely...
The Svord Peasant
Of course as your attorney I advise you to get into balisong knives instead which are universally inherently ambidextrous.
I have a couple and a trainer... But not good for EDC from a legal standing. Although i need to look into the legalities of a trainer.
Another vote here for the QSP Penguin. Grabbed one this year to replace a Benchmade, and I love it!
