I just dropped off my planer blades to be reground. one set is fine, but the other has a nick about 1/1/2 inches from the edge. I got the set for $5 thinking I could use them as a back up set. I have never planed anything over 6-8 inches, so I took the chance. At the sharpening shop, a guy( customer not an employee) told me that I should "cut the nicked set down and use the shorten piece to make an extra set of jointer blades. The minimum width for both jointer and planer are the same, but other wise I don't know if they are the same.
1. I have no intention of doing this, but it got me to wondering, could that be done?
2. If the cut could be made would the blades be usable in the jointer?
3. Why does this make my teeth hurt?
The guy seemed real sure it was no big deal and he knew it was a SS set of blades. All the fingers were still there, and not major scars showing.

How big(wide) is the nick? If not too wide, you could stagger the blades so the nick(s) are cleaned up by the other two blades(three nicks located off set from each other).

I believe other than the length, the blades are the same.

Are the planer blades tapered?

As I said, I have no intention of actually doing this, but it was interesting.

The nicks are deep enough that they " may not come out" according to the guy at the shop. They are narrow and I might off set them enough to eliminate the effect of the damage. They are my back up anyway and I have used them as they are. I can buy a new set of jointer blades for far less than the planer blades, so I would be foolish to cut them down and then buy planer blades. I was just intrigued by the idea. As far as I know, the blades are the same except for length. But, I don't know very far! Add to that the lack of experience that I have with these things, very sharp stuff spinning at very high speeds and the possibility of one of them flying off if things are not right, I will keep this at the level of an "intellectual" exercise.

Just like the jointer blades!

So? Is the guy right? It would seem that the cutting of the planer blades might work. How would you cut them?

The guy is right in that it would work. An abrasive cutoff wheel would cut them.

However not a good thing to do as has been already mentioned(think planer blade $ vs jointer blade $).

What about mixing the blade sets? Take one of the nicked blades and swap it with one from the good set. This way if the nick can't be completely ground out the other blades will plane out the ridge.

Well, as I said, I will not be doing the cut off thing, but I was interested in the idea. My good set has lots of wear left and there is no reason cut them anyway.
I have the other set with a notch and they are so narrow that any more sharpening after this touch up they are going to be to narrow to use. ( they may be after this one) I will just use them as a spare. I don't think I would pair them up with another set, just because at that point, I will need a new set anyway.

Now for the next question!! After the old set is to narrow to reinstall, what are the possible uses for these blades?
