I went shopping last night with a friend who is going to buy a circular saw as well as other tools. While at Home Depot, we noticed that some circular saws have the blade on the left side and some on the right (no indication from manufacturers as to why).

We were speculating that these are for right handed people or left handed people. I am guessing that I would want the blade on the right so that if I were cutting a sheet of plywood, I would keep the saw over the main piece of wood and trim off the right.

Anyone know the answer to this puzzle?
