Ok, let me preface this by saying I'm apparently a tungsten officionado... I have the 1cm, 0.5in, 1in, 1.5in, and 2in cubes, AND have two 1cm dice (and am currently on Amazon to buy more.......). They're great (and incredibly useful when you need a nice, heavy weight that won't get in the way - like, for sewing or woodworking). But this particular one... has sharp edges. It's not comfortable to hold in my hands because it feels sharp continuously.
