What saw blades can cut through bone?
You can rent a miter saw from places like Home Depot. Here’s what they look like. http://www.dewalt.com/us/products/tool_d… I have one myself and it would be ideal for your project with a fine toothed blade. The saw is mounted on a frame and you simple place the piece to be cut on the deck and lower the spinning saw with the handle. Each cut would take a couple of seconds and virtually no effort. A 32 tooth bi-metal blade should do it. You could also use a frame mounted band saw but that would be overkill unless you are cutting giant cow bones.
