Lil' Temperance: If you like the handle color, this knife is a great little worker. It'll do MBC, utility work, field work, whatever you can throw at it that doesn't require a serrated edge. I personally feel that a knife designed for tactical usage should have a tactical look, and while some people like the change from plain old black G-10, I happen to like said black scale material.
Salsa: Great lil' sheeple-friendly box cutter. The first words out of a female coworker's mouth when I opened it were "it's cute!" Not something you hear everyday about a knife. Despite its size, it is a hardy little cutter for everyday tasks. Not exactly a field dressing knife, though, but you wouldn't need a "cute" knife for that anyway. The compression lock is very solid, either nested or integral. My blue aluminum Salsa feels secure and comfortable in my hands, but the compresion lock, at least to me at the moment, is not the fastest-closing lock, but it works well, and putting it away fast is not really a concern unless I'm really busy.
Gunting: Designed for MBC. The best uses of this knife seem to come while it's still closed. The cusp on the back of the blade and the dull point on the butt of the handle are nonlethal control devices, for targeting pressure points. Open, the knife is comfortable in just about any grip, forward or reverse. Besides its obvious MBC use, it actually makes a good EDC utility knife, though it's not the most sheeple-friendly of Spyderco's offerings, so make sure of the people around you when you use it. The compression lock, again, is very solid. Spyderco is putting this lock on most of the knives designed as MBC knives, the only notable exception being the Chinook, which has a strong lockback.
Chinook: A folding bowie. This is a serious knife. Looks means, acts mean. MBC and field work are all I'd use this for: even knife people would get nervous if I used this in an everyday fashion. Modified trailing-point Bowie blade, with a solid G-10 handle and Spyderco's strongest lockback to date.
Perrin Street Bowie: For a fixed-blade, it's pretty sheeple-friendly. Like a kitchen knife that can be sheathed for defense or field work, or an MBC knife that's at home in the kitchen. Krayton inserts mean you won't lose your grip on the knife. It also has texturing on the spine, giving extra purchase for your thumb. Lends itself well to any task: put serrations on the spine or rear of the primary edge for the tough cuts and you'd have a good offering for any armed forces use.
Temperance: A smaller, drop-point fixed blade. Again designed for MBC, it has an angle between blade and handle to offer a more comfortable holding position in the forward grip. The point faces forward while your wrist doesn't need to be twisted as much, leading to a more comfortable, secure grip. Indexing holes mean you can find, draw, and change grips faster.
Native: Dunno the last time you looked at the catalogue, but the Native was my first buy about 2 months ago, and started me on the path to a major case of the Spydies. It feels perfect in your hand, and adapts well to most any task, from box-cutting to pruning. Even in FRN, it's elegant, with a radial pattern providing excellent texture to prevent slips, and a deep choil and spine texturing to give a firm grip with thumb and forefinger for controlled cutting.
