I meant to post this a long time ago but I keep forgetting. I am building some shelves in the basement with this shelving material we bought from a building supply store. I was just wondering what kind of blade I should use with the circular saw? I have a feeling that if I use a aggressive tooth one it may tear the board apart. So should I use one with more small teeth, or less teeth and large teeth? here is a picture of the board to get an idea what I will be cutting: Thanks!
