What are the best ways to groove and prep tires now?

I been noticing a lot of different patterns people grove on there tires, some people sipe them and some don't. I haven't really done anything to mine besides cut the main grooves out alittle bigger. Wondering what are some good ways to do them.

There was a nice article in Speedway or Stock Car magazine last month that covered grooving and siping. Just do a google search and I'm sure you can find many articles about it.
