Question about those cheap dive knives from online marketplaces

I bought a 'professional' dive knife for 25 bucks off one of those big online marketplaces last fall. It looked good in the pictures, stainless steel and a serrated edge. First real job with it was a simple line cut on a buoy in Galveston Bay. The blade snapped clean off at the hilt when I put any real pressure on it. Not a bend, a full snap. I was left holding a useless handle 30 feet down. Had to surface, get a backup, and go back down, which killed about an hour of billable time. That 25 dollar knife probably cost me 300 in lost work. The metal was clearly junk. Has anyone found a truly reliable brand for a basic utility knife that won't fail like that?

Oh man, that's the classic marketplace special right there. Looks like a tool in the photo, turns into a liability the second you need it to actually work. You didn't buy a dive knife, you bought a single-use snap-off blade disguised as one. Isn't it funny how the price tag always comes back to bite you?

Yeah, I learned that lesson the hard way too.

Wait, a single-use snap-off blade? That's a new level of cheap! What are you supposed to do if you actually need it underwater, just hope it doesn't break? The whole point is having a reliable tool in an emergency. Saving a few bucks isn't worth that kind of risk.
