Way too thick and heavy to be anything but a wallhanger.
"The blade is 1cm thick at its thickest, and the knife weighs over a pound. It looks really neat, but if they had cut the blade thickness in half and maybe shortened it about an inch it could be a useful knife. As is, it pretty much matches the "mall ninja knife" definition. The plastic grips are so slick that a knife of this weight would slip if used for any kind of cutting motion. If I had handled one in person first, I wouldn't have bought it."
