Knives (key chain knife that looks like a key, pocket knife with fold out locking blade that has interchangeable blades with box cutters)

I have several of the former from various eras. They seem to be universally crap, which is disappointing. Some states (California leaps to mind) also have laws against knives that are disguised look like other things. This is objectively stupid, but it’s how it is.

For the latter, might I suggest this or this? Just sayin’, as they say.
