I have two Spec-Plus knives, the Marine SP-1 and the Quartermaster. Both mine are good knives, although I have used the Marine model more. Chops decently, slices and dices ok. I haven't chipped out the edge yet, and it does get nice and sharp. Put a toothey edge (medium stone edge) on it and it'll get alot of work done!
The handles are grippy and comfortable, hasn't caused any hot-spots for me yet. I have the top handguard cut off of the Quartermaster, and I like it enough that I'll probably do it to the Marine, too. It is easier to whittle without it. And, I added paracord lanyards and tossed the shoestrings that came with them.
As for the coating, I could do without it. It scratches up easily, and is chipping off near the cutting edge on my Marine. I would prefer eithor a parkerized, military spec finish, or a brushed or polished finish so it could be develope a natural patina. I love the look of 1095 with a nice patina!
The sheath is servicable, nothing spectacular. It would be better with a pouch as the Beckers have.
Never owned the Freedom Fighter series, but they do look really nice.
Overall, especially at their prices, I think the Spec-Plus series are great general purpose user knives.
