Reusing ‘Disposable’ Planer Blades

Is there a way to safely hone 13-inch throwaway planer blades for reuse?

Richard Jones: A light touchup with a fine stone to reduce small nicks will work, but a proper resharpening may mean that, after refitting, the blades describe too small an arc. This could result in the infeed and outfeed rollers, chipbreaker and anti-kick back pawls being out of line, which can cause chattering, poor cutting or even possibly cause the wood to hang up as it passes through.
