So what do I do if I cut myself?

Alum blocks are effective both in cost and don't sting like some styptics do.
Lots of overpriced alum blocks out there but often Asian or world foods shops sell them cheap.
I would look to spend less than a fiver on 50g if you can.
Alum blocks all the way for me...... works wonders.... side issues. Slow down, consider different (calmer ) blades, depending on what your using. I'm no expert but I found using milder blades reduced the number of cuts...
 
This may well be worth a try. I got the pro raso and got the alum block to give it a go, just hoping to cut myself soon to give it a go!
