   I think you could probably send out for sharpening. In the end, a hand plane should hit all surfaces anyway. For that reason, I don't get hung up on finish from the planer. The cats meow is the helical head but they are big $$.

   I used to have knives in my 16 inch planer and switched to a helical head. If not, buy a second set of knives from a place like Infinity. Then find a good sharpening service to sharpen the old set and rotate your knives from the sharpener to the planer. Send the dull set to the sharpener and install the sharp knives. You will always have a sharp set of knives on hand. You really shouldn't need to buy new knives each time you need to have sharp blades. A store like Woodcraft usually knows of a good sharpening service.
