oh my god I've had this problem so many times before......my Phone Number eye kohl should be half gone and because of it constantly breaking, it's now almost gone!......it's soooo frustrating.......I've figured it out though.....it won't sharpen because it's somewhat melted.......even after I sharpen it every time I have to reshape it and clean off the woodshavings....I once got a woodshaving in my eye because the thing was melted...seriously, I love the blendability of the eye kohls but they really need to get a better product...and one that isn't hazardous!..I hate these things!.........
