grooves in ur irons

The way I understand it is that the benefit of square grooves vs U grooves or V grooves is that a square has greater volume than a U or a V. Again, somebody correct me if I'm wrong here, but if I recall correctly, the main purpose of grooves is to give a channel for dirt, water, grass, rocks, etc., to go in so they do not get pinched between the ball and the face. With a channel of greater volume, more of the dirt and water and grass will be taken into the groove, giving you cleaner contact with the face. If you were to hit two identical wedges, one with grooves one without grooves, you would notice that the ball would have almost the exact same flight characteristics (spin, trajectory, stopping, etc.). The only time you'll notice a large difference is when you get into the freshly cut grass, or in the morning dew, etc.

Think of it in terms of tires. If you want the most traction on a dry, clean road, you're going to use "slicks" that have absolutely no tread whatsoever. However, if you're going to be driving in rainy Seattle, or in snowy Alaska, you're going to want some tread to channel the water, snow, and dirt away, so you can get some traction on the road.
