The Flash, Trident and Aegis knives have different shapes, but they're practically identical on a mechanical level. They all have metal-free zytel handles and SOG's propietary piston-based locking mechanism. The piston lock tends allow some up-down play, especially as it wears in, and the handles always have a bit of give, meaning there's lateral play as well.
I've handled a number of all three knives, and never found one that didn't have some play.
Having said that, this is an under $50 knife, even in Canada. However acceptable people find it, there will always be loose blades in that price range. The Flash, Trident, and Aegis knives are nonetheless solid cutting tools and make good beater knives. I used one for cutting duct tape and duvotene and other stuff that would have dirtied my primary blade.
