I have a fancy wood/metal barstool that does not fit too well in the kitchen island in our new home. The legs of the barstool are made up of metal probably hollow steel. I need to shorten the legs of the stool by about 3 inches. What can I use to get this accomplished? Is there any reasonable miter saw (blade) that can cut thru metal. I know this is a newbie question but I am clueless.
