Any tips or tricks? Mine are dull and have a nick or two that I need to get out.

Or should I just replace?

I sharpen mine by hand on diamond stones. You could make a jig to hold them but I never did. Have done up to 20 inch blades this way. My 13 inch blades take about 20 minutes.

Consider sending them out.
Its hard to beat a man at his own game and the sharpening shops have fantastic equipment to get a sharp edge very straight.
The sharpening service I use, Jamison's, has a sharpening machine that cost six figures. When I get my knives back I can shave my arm with them.

Very thin knives may be easy to sharpen without a big grinding machine.

I successfully sharpened the 10 inch blades of my old AP-10 shortly after getting it. The guy who sold it to me thought it didn't work anymore and didn't know what was wrong. When I Iooked at the blades I knew what was wrong. They looked like they'd never been sharpened. About as sharp as a butter knife. So I used my Worksharp 3000 on them without any special jig. Worked well. I later replaced them, temporarily, with a spare set I bought before sharpening the originals and the spare set seems to be softer steel. I like the ability to sharpen the blades, saves some not insignificant money.

For me, it's wrap them up good, insert in a Flat Rate Box, and mail them to Dynamic saw. There is a jointer knife sharpening jig in the classifieds right now, FYI

What kind of planer? It depends on the planer and size of knives. On smaller planers its only a little more expensive to buy new ones.

For me, with 20" x 4 knives its is too expensive to buy a new (decent) set of knives. The cost to have them done is not worth me sharpening myself, even though I have a sharpener and a jig.

I'm going the same way with my mower blades next year. For $5 a piece, I'm not doing them myself anymore.

Can you post the contact info for the place you send them?

Thanks!

The planner is a Griz G1017. 12.5" blades.

I sharpened them myself. They were nicked pretty bad so I ground them out with my slow speed water wheel. Then to the diamond stones and went to work.... freehand. I probably should have made a jig but I know how to sharpen and I was lazy today.

Took about 30 minutes and I had them sharp. Are they professional sharp... No. Are they sharp... Yes.

If I had a spare set I would have sent these off just to see the result.
