I've used the Forester, Swick and Aqua Salt all quite a bit. I've been interested in the Rock Salt for a long time and would be buying one at their current price if I had the spare $$ for knives.
The Swick is a nice EDC, neck knife or compact fixed blade utility knife. It's like a highly ergonomic CPM S30V box cutter with seriously good grip retention.
The Aqua Salt is a tough, stain proof utility blade that can be servicable in a variety of applications. Food prep in the kitchen, gardening, camp utility, fishing / marine use etc. Great smaller blade.
The Forester is a very fun knife to swing around. Compared to my Scrapyard Dogfather its lighter, so it's less of a full on wood chopper, kind of like an overbuilt machete in a sense. It can do a good job of trimming up trail paths, breaking apart firewood, building shelters and all that fun stuff. Only negatives is under intense chopping it's possible to loosen the handle scales (Loc tite would fix that) and while you can use some muscle with this knife while prying, it's not something I'd pry very hard with like I would the scrapyard. Not something I typically do with my knives but with the big fixed blades sometimes I end up prying apart wood. The sheath it comes with is very nice overall, except it's a bit looser retention-wise than I like. Amazing value for the price you can currently purchase them for.
