Grooving is fun, I think. Well, for the first 1/3 of the first tire.Grooving tires takes a lot of time. I have only seen this in cases where a tire reseller wants to deepen the groove to make the tread depth deeper, not add new grooves, but the hand held tool isn't a fast option.

I've done lots of it, primarily to create a more flexible contact patch.
