I'll start


In order of appearance...
1. The Aqua Salt has to be one of the most versatile small fixed blades ever made. Lightweight, tough, secure grip in all conditions, rust proof and big enough for any outdoors task short of machete use. I hadn't carried mine in a while, but I took it backpacking this spring and was reminded of how great it is. I used the cruwear Temperance in the same location on another trip and put it to the same uses. The cruwear blade came away with minor dings and rolls, and orange specks across the entire blade simply from rain. The H1 Aqua Salt showed no rolling, chipping or corrosion at all. It's toughness is up there with its corrosion resistance. This one has been batoning logs up to 8" and prying chunks off fatwood stumps since the 2000's with no complaints.
2. The Police is my favorite folder design, and this is my favorite version. The G10 aftermarket scales add a little width to the handle, making it more palm filling. The PD1 blade with DLC coating has held up well in all respects - good edge holding, sharpenability, toughness and corrosion resistance. It cuts and carries extremely well,with a handle that manages to be slim and ergonomic at the same time. Fingers crossed we get a salt!
3. The Military 2 Salt is my favorite folder at the moment. While I prefer the design of the Police, to me there's no better material selection than what this folder offers. Magnacut is the best rust proof steel I've tried so far in terms of edge holding. I love the textured G10. The Military 2 is lightweight, easy to carry, has rock solid lock-up and very smooth action. Really excited to pick up more magnacut & G10 salts once they expand the line.
4. C95 Manix. While the Military Salt gets the nod for versatility in all conditions, and the Police is the best overall design to me, the C95 Manix is a heavy duty work horse with the most ergonomic handle in Spydercos folding line-up in my opinion. There are many different aspects of the handle I love for more rugged jobs - the secure guards on both ends, the placement of the finger grooves, the mellow thumb ramp, and the sheer thickness of the handle. Not the thinnest in the pocket or the lightest - but the go to choice for when I expect tough cutting jobs and plan to tackle them with a folder.
5. The Street Beat is my favorite EDC sized fixed blade. It's very light and compact but doesn't feel undersized for most utility and outdoors tasks. Whether it's slicing up a cardboard box, cutting paracord, carving feather sticks, slicing steaks or cleaning fish, the Street Beat can handle it all with ease. I've been carrying either the lightweight or the micarta version for EDC and outdoors adventures since the 2000's, and they've never let me down. A true gem in Spydercos line-up many folks overlook simply for not being a folder.
Honorable mentions....
