My Company sharpens planer blades for about $8 per blade + $0.50 per inch.
We do a two-stage sharpening cutting a coarse grind at one angle and then we do what we call a micro-bevel which is a fine-grind at a slightly different angle, doing so ensures the blade stays sharper longer and actually exceeds the factory sharpening.
