The Ontario Knife Company has good folders for very cheap one would normally pay double for, found on amazon like most of them.
Cold Steel has many nice tools.
Don’t go anywhere normally without two blades, and walking/running carry a small fixed blade on thick wide belt.

OKC Rat 1 & 2 are excellent inexpensive SD folders. CRKT also makes very trustworthy knives in that price range.
