Hey there, you don't need a razor or anything to split the blunt. I believe half the fun of blazing comes from rolling your own tight blunt without using anything but your hands... lol just the way I am.

But my first tip is always use a grape swisher. Next make sure you break up all the bud you plan on rolling up before opening the packaging of the swisher. When you DO end up opening the blunt, put the tip of the blunt(not the mouthpiece end) between both your thumbs, and squeeze the part facing you so the tip is cornered or like you folded a piece of paper.

When I start to split the blunt I have it positioned between my two index fingers and thumbs. Pull away on each side of the little fold with your thumbs and it will start the split off pretty straight then you kinda shimmy your fingers down as your splitting the blunt. I've never ripped/ruined a blunt for years and I do this every single day.

Sorry if I didn't explain it too well, I just want you to be able to roll your own blunt and have the satisfaction of smoking your own creation, ya know? lol:thumbsup:
