Recently I've been cutting my nails to end in points. Seems like a good idea to me to add a little extra damage to strikes to the eyes and for a little extra leverage when grappling. (And also could be very good to get to pressure points)

If anyone has any thoughts or knowledge about this I'd be interested in hearing them. Any ideas how to get them to be as sharp as possible or to cause the nails to grow thicker?

I don't know if I could get them to the point where I could cut through surface veins anytime I grabbed someone but that would be ideal.
