Do serger knives need to be sharpened?

    They do get dull, but I've never read that they could be sharpened (of course I haven't read everything out there either!). They do need to be replaced periodically. I think generally one knife is harder than the other and therefore doesn't need to be replaced as often. The harder one is supposed to be replaced by the dealer (I think it's an alignment issue) and the softer one is often designed to be replaced by the user.

    A few people are successful in sharpening them, but generally it is better to just replace them. Along with the edge getting dull, the rapid motion wears down the surfaces, and the mesh between them gets continually worse. Valerie's comments about the different typs of blades is correct, but only on some models. If the serger has a system with one harder blade, this one will be much more expensive than the other. Many good dealers will be happy to replace your blades, frequently free of labor charge while you wait, if you catch them when they're not real busy and you bought the serger from them.

    I have heard some nightmarish comments from people messigng with thier serger blades such as coming loose, etc during serging.  I would only let a professional change my serger blades.
