So far it's done a great job jointing boards. I found replacement knives for it at American National Knife. Call Toll Free: 1-800-533-7117 and tell them that you have this blade: hss blade: 6.1 x 0.65 x 0.07 in / 154.5 x 16.5 x 2 mm. Otherwise, it's not the one I really wanted, but surprisingly I'm happy with it. Does its job.
