Sharpen or buy new knives for Delta 13" planer 22-580

What a waste, High tech steel just thrown away. And you wonder why this country is in such a mess. I just wouldn't buy anything with disposable blades - well, I don't sharpen my razor blades, but I've thought about it.

These blades are indexed to the cutter-head, and so any sharpening will reduce the height of blades, and change the relationship with the rollers.
Only left/right movement is possible with the blades to shift them if you pick-up a nick in them. Shifting the blades will allow you to continue on, until you pick-up too many nicks.

The magnetic guides for setting blades is used with cutter-heads that are 'not' indexed.

If you sharpen these blades then it is possible that one blade will have just a little bit more or less metal removed, then the longer blade will end-up doing all the cutting.

I would only go as far as a simple honing on these blades, since that does not remove any appreciable metal, otherwise it's time to dole out some cash for new ones.

If you make your own tools, then you might be able to use the old blades for tool steel.

Greg, I've got new blades, the magnetic blade changer and the wrench. I sent you a PM.

As mentioned these blades are disposable and have no adjustment.

I have however had pretty good success touching up blades using a homemade jig and the scary sharp method as long as there are no nicks in the blade. Just keep in mind you cannot take of too much material.
Usually about 2-3 touch ups and it's time for a new set but considering you have 2 edges. 2 sharpening x 2 side = 2 sets of blades $$$ saved.

Exactly true,Danny. All I would advise is a little hand honing,but some folks don't want good advice.
