The Paraframe II is a one-handed opening stainless steel knife with an open frame. The blade can be opened with one hand, but it doesn't really go easy with one hand. The frame-lock on the other hand is rock solid, not matter if the blade is in open or closed position
I use the knife quite frequently - for cutting open packaging, going on a mushroom foray or to disembowel fish. It's a great knife. However, when cutting cardboard the knife requires more frequent sharpening.
The size is good, the clip is strong and the knife has a constant place in my backpack.
