Wish I had remembered how hard they are. I used some to screw a jig
together. The points were sticking out a trifle at the bottom, so I
whipped out my handy dandy X-Acto razor saw.

Such a pity. I used that stupid thing all the time for cutting everything,
but now it's ruined unless I find some reallllly tiny needle files to put
new points on it.
