This is a pretty good knife, it sharpens quickly and holds a decent edge. Out of the box it was sharp enough to use if you needed to but, like most factory edges, it wasn't as sharp as it could be. The grind was even. I don't know if I would qualify this as a hard use knife, but time will tell. It should do well as a skinning knife and for general camp chores.
The four star rating was because of the sheath. The knife is made in the USA, the sheath is from China. It holds the knife, and you can attach it to a belt, but I don't see it holding up for an extended period if time.
