Super Knife!
This thing cuts foam easily. It's an excellent buy. However, a word of caution: It will also slice your hand, fingers, etc. if you aren't super careful. I managed to cut myself while trying to close it. I am glad I purchased it.

Handle I'd large offering sure grip
I prefer serrated blades even though I like sharpening knives. The sawing action get through alot of stuff easily. Iv used for light yard work and cutting alot of cardboard boxs. I can sharpen one side well and it keeps a decent edge. Very sharp and not a toy. This is a thin light sharp work blade for sure. My wife ised it to cut up a chicken she likes the grip. It's a big grip about 1.5 in. Which is real good
