Those little buggers are rugged, and leave allot of space in between the blades in comparison to most knives that style thus avoiding allot of the problems that can arise.
If a small multi-blade knife is your cup of tea, and you want something inexpensive yet dependable, they are certainly a good choice.
I bought one some years ago because I wanted a smaller lighter and more "socially acceptable" blade and didn't have the money or time to spend looking for one with better steel.
While I replaced it with yet another small buck (the single blade lock back with the wooden handle and silver bolsters, can't remember the model now) because I needed one that was a little better balanced and wouldn't fold up on me, I was quite impressed with it's over all dependability and ruggedness for such a small multiblade.
(Eventually I replaced the small Buck lockback with a Boker model which had much better bladesteel).
While I found the steel lacking the properties I wanted, I can't complain about the overall construction and price and can certainly see where it would be an excellent knife for the right person.
The right knife is judged by it's comatability with the person who's using it.
