Lucky for me, my wife is a pushover if I need a new tool. Of course, the general requirements for each new project are (1) spill some blood, and (2) a new tool. That being said, this time I am here to crow about a tool I have had for a few years. A number of years ago I bought a Bosch laser level that projects both a vertical and horizontal laser line. Originally, I bought it to use to hang cabinets in my shop, pictures and paintings in our home. Currently I am tiling a shower in a "brick/running bond" pattern. What an amazing help that laser is to keep the pattern correct between the 3 walls of the shower!
