Reddit reviews Cold Steel Code 4 Folder 3.5 in Spear Pt Plain Gray Aluminum, Gray, 3.5"

My vote would be sebenza or benchmade.

Love spyderco but they lack warranty and replacement parts, which you want in a lifetime knife.

Left handed? No knife lock better than a axis lock (except maybe a back lock)

Bladewise, I am not the fondest of the 940 blade shape. Kind of chunky. I will say this, I love the look of a Mini Crooked River, and I think it is classic.

Any aluminum handles benchmade with wear nice and look awesome with some wear. That is the draw of the 940 in my opinion. Looks amazing with some wear on it. Like the Arcane

G10 handles are like indestructible, the griptillian has an awesome steel with two blade shaped to pick from. Even better with the Freek in g10. Absolutely amazing shape.

Benchmade bugout has an amazing blade, I've heard, but has kind flimsy scales. If you want one for a forever knife, get a pair of titanium scales. It would be similar to a 940 but with better blade grind.

Totally left field here, if you want an Indestructable knife that will whether nice and survive everything, consider the Cold Steel Code 4. Triad locks when broken in, drop shut and flick open easy. Weight isn't bad, blade shape is useful and aluminum handle is handsome. Take it as someone who hates most cold steel, the Code 4 is a gem. See here

Now, Sebenzas have been mentioned, super usable shape and great quality! Expensive but good to get used.

One final option, is a few left handed Kizer knives. The one I think of mostly is the Gemini, designed by Ray Laconico. They have it in left hand frame lock, same steel ad the sebenza, and I think it is a handsome design that will last you well!
