the thicker ruler does not make it easier, though i can see why we would think it might. actually if your ruler is thicker than about the 1/8" norm your cutting is not as accurate; thinner is better in this case. it is very important to always practice safety first and holding your hand on the ruler with a finger or 2 off the ruler braced on the table beside the ruler holding it so it can not move is best. it takes some practice to really cut accurately but a thicker ruler will make that more difficult, not easier.
