I use a box cutter knife.
I was playing it with one day and running it over my hand and found out after a while I could run the blade at a 30 degree angle at the direction I was going at without cutting into my skin. So I decided I could shave that way and I did 
Haven't used a regular blade yet
dude you have balls of steel. There's a huge difference between a sharp blade and a sharp pointy blade. I would never use a blade with a point o_o
The make rounded edge box cutter blades. Must industrial areas need to use them unless ABSOLUTELY necessary to use the pointed edge variety. OSHA are such wusses.
Didn't know that, good to know they exist. I happen to agree with OSHA on this.. why not enforce safer tools when the danger traditional tools offer is unnecessary?
I'm of the mentality that if you round every corner on every table, desk, counter top, blade, cart, arm rest, etc... you're simply inviting complacency into the workplace, especially in lines of work where you can lose your life in a heart beat. My job requires me to climb around in a racking system over 90 feet tall on metal rails about 1 1/4" wide. If a person can't be safe and smart around a non-rounded razor blade, odds are they shouldn't be up in the racking.
One of those darwin theory things.
If you need sharp corners then use something specifically for that. If you have absolutely no need for a sharp corner, then why would it even be a feature? A sharp point on a blade when all that is required is a sharp edge is unnecessarily dangerous. I don't really think that's an opinion.
Many public staircases have embedded rubber traction. Is it required to walk up safely? Nope. Is it a feature that prevents accidents and even deaths? Absolutely.
Incompetent people aren't the only ones who can get hurt. I'd rather provide a safer workplace for both smart and dumb people - not set up dumb people to hurt themselves.
Also, from an engineering standpoint, an unsafe tool is a poorly designed one. Not every blade needs a sharp point.

Sorry for going off topic.
