So, yesterday I was shaving with one of my straights that has a squared point on the end (I have about half with rounded points and half with squared). That point gave me a good slice on the cheek.

The razor shaves fine apart from that. What I am wondering is.... what is the best way to round the ends of my squared razors so that this doesn't happen again? Can it be done using mere hand tools like a dremel or do you need a grinder or belt sander (My grinders and sanders were sold when I moved)?

What would you recommend (yes I know shaving technique is important but this has never happened with any of my rounded points).
