I bought a bench mounted belt sander – the type with a longish belt in the front usually vertical and a circular disc on the side – and mounted it on the end of the bench. Now every piece of stock I cut, and the remaining bit, gets a (very) quick dress up on the belt to take the sharp edge off, as does any stock I buy if it arrives with a sharp edge. I say 'a (very) quick dress up' because that's all it takes, literally seconds, but it drastically reduces the chance of a cut hand. So a no-brainer.
The bits I mill have the edges dressed with a file, as do any circular ends on lathe produced parts unless a chamfer has been put on, but I guess most folks would do that anyway as a matter of course. Saves cuts to hands!
I also mark each end of the bar stock with the EN number and the size to help ID it later when I have forgotten what I do have with a Sharpie, takes the guesswork out later. It helps me anyway!
