BM 550:
440C steel, thick steel liners, opening hole, *AXIS-lock*, deeply checkered Noryl GTX, treads for grip on both the spine and the steel liners, treads the underside of the handle, treads for use in reverse grip, contoured handles, reversable clip, along with a pretty well-defined "guard" for the index finger.
'Nuff said.
Now, you go up the BM line to something like the 806D2 or the 710HS, there is absolutely no comparison.
If you just want a knife to cut, you can always get a Stanley box cutter. You pay more for a well-thought out and well-executed folding knife design. Which is why it comes down to getting the best one can afford, and *feels suits one's needs best*. I don't think anyone knocks CS for not making a good knife, but almost no-one calls them a high-end production knife company.
The original poster placed his price range at under $100. For under $100, there are many better knives (material, design, cutting efficiency) than a CS Voyager.
