I needed to cut down a few sets of carbon handlebars and thought it would be easier to do it at home with the right tools. I bought a Park tool Saw guide and this tungsten saw blade and went to work. The first bars were a try it and see, and to my surprise I had no issues. The other bars went fine after that. Just make sure you use tape to mask where you want to cut. I used red electrical tape because it;s easier to see when the bars are in the saw guide.
