Nice, I'm getting real close to a 16 also. I don't think I ever received a knife and the grinds where perfect. They are always off a bit, when people are doing this by hand it's going to happen.
Cure: I put it on the wicked edge and put my desire grind on it. Most of the time I keep it a bout 40 degrees inclusive or less so I can touch up on sharp maker.
Nice grab.
