Ok, what kind of file did you use, any sharpening tips for toothed plane blades, teeth per inch etc...? C'mon....

What kind of file to tooth the blade?

No file will cut a hardened tool steel blade. If you want to tooth the blade with a file you need to do this while the steel is still in its soft (annealed) state.

For modifying and existing blade I would try a cutoff wheel in a dremel type tool. For hardened steel a grinding operation of some sort is the only answer.

Oh No! Not another learning experience!

I've made several toothed blades for my (homemade) fingerplanes as Louis mentioned - mounted a dremel cutoff wheel in the drillpress, clamped the blade (horizontal) to a block & gently cut teeth in the sharpened blade. The 10mm blades have 8 teeth. They work great- unbeatable for high figure. (The blades themselves are made from old 8mm & 10mm wide files.)

Just to be sure: you want to tooth the blade so you can follow your planing and/or cut difficult/curly wood, right? Not because of that antiquated (and wrong) idea that a toothed surface provides a better glue joint with anything other than epoxy?
