We always used to say, snap the tile with the tile break facing away from you using your fingers, not slamming the back of the score on an object forcing the cut (razor sharp, glass-type glaze effect) to skim your hand/palm/wrist and chopping bits of like a kebab.
Really really nasty sharp tiles are.
Hope you're back on the tools soon mate, if not already. (I've worked with a broken hand before and then as soon as it was plastered I was shaping the plaster cast to fit my tools.)
Get Well Soon
