while the concept is great, this particular exection is poorly made. I ordered one to replace my old HK which seems to have gotten lost. I received a Spoo-Key brand instead of a HK. Looks the same, same size, same chrome finish, same all around. But this one is nowhere near being balanced. I actually taped a dime to one edge of the key loop (the one opposite the teeth, or tines) and it still wouldn't balance. The loop is uniformly thick (not like the original HK) and pretty much centered on the keys shank (again, not like my original HK). Net result: this thing takes a hugely obvious tilt of the hand to get it rolling, and once it passes center-point, no matter how slowly you go, it plops over with no way to control it. Straddle it across 2 sharpies and and you'll se what I mean--the teeth roll downwards no matter how carefully you place it. Not the right brand. Pass this by.
