Sawhorses come in handy first and foremost for sawing something. They give a sturdy surface and proper height to cut cleanly and evenly. Depending on the length of your material, you may only need one sawhorse, but ask any avid DIYer or carpenter and they will tell you to have two. Two sawhorses give you the ability to create a work surface by placing a piece of plywood (or old door!) on top, with each sawhorse offering support at either end. Not to mention, a pair makes it easier to cut long lengths of lumber or pipe, with or without a platform between. Sawhorses are often made of wood themselves, with a beam and triangle supports at either end, and are often designed to fold or stack for easy storage. You can purchase sawhorses at any home improvement store, but if you really want to go the extra mile, why not make your own?
