My machining skills, 2

I thought my skills were improving, and they probably are.
However, I was able to cut myself, not on the machine, but by handling a part that I just cut.
It was a partial cut, where I could break the end by just twisting it… I snapped the part off where it was supposed to, but in the process I squished my finger, in the process cutting it.
