Review on AFA Tooling Deburring Tungsten Carbide by Hassan Tomlinson

Take this review with a grain of salt as I use plastic. However, it works better than I expected. Deburring holes is not difficult at all and deburring edges is also easy with a little practice. You should pull the blade gently and use the bead at the end of the blade to hook the edge. My first attempts yielded a broken edge until I mastered the technique. I can't say anything about metal because I haven't tried it yet. It's me after all. For those deburring plastic this is a winner though, much better than the Xacto knife.
