I would look more at blade composition. Some use crappy Chinese steel that dulls quickly and won’t hold an edge. If your not worried about rust go high carbon blade. I prefer American but Opinel is hard to beat and cheap. I use a #7.

If you like stainless I prefer a S30v or better but your not gonna get that for $30. It’s a little harder to sharpen but holds a edge really well and once it’s sharp it’s nothing to touch it up. If you want cheaper and easier to sharpen go with a 440c
