I have never seen a NH haybine that didnt have serrated sections, and serrated sections are self sharpening. Unless your sections are plain wore out, here are two things you can look for. First are the hold downs holding the knife down tightly to the guards? And second, are the tops of the guards bent away too high from the knife sections? As others have already said, maybe time to just go buy another complete knife assembly. I used to buy a new knife every 2-3 years. If your knife isnt cutting well, or is hard to push in and pull back, then you could have guards that are bent up or down, making the knife run hard. This puts a pile of stress on the wobble box as well as the rubber bushing in the end of the knife. Do you have a guard bender tool ?
