The EKA Swede 92 (aka the Normark American Hunter)
is very easy to take apart. Just two screws with large heads that take a penny or dime in their slot to unscrew. Putting it together was a little tricky at first, but after doing it a few times it's easy. The Swede 92 isn't one hand opening so it may not be suitable for what you have in mind but it makes a great beater knife at around $30.00. Only a few internet stores seem to carry the knife, and I wonder why.
