Scythe blade warped while peening

[Vic Dupont]

Quoting another thread:

Well, since there isn't an agricultural tools section this seems like the best place

I warped my blade while peening it.

Several reasons could be the cause :

• it was my first time peening a scythe
• that scythe had never been peened, while used for decades, thus a lot of peening was required
• it had many dents, though not huge, and I tried to fix one until it disappeared
• I pounded on the center of the blade at some point

After doing some reading, it seems the most likely cause is that I pounded on the center of the blade, not only on the edge. I had seen that the edge was curling back on itself too much and wanted to straighten it. I thus pounded with the flat of the hammer, a bit everywhere, including in the middle of the blade. I think the warping appeared right after that.

Here are some pictures.

Do you guys think I might be able to straighten it?

Or is it that the cause of the warping might be that the metal was spread out too much, and thus won't be able to flatten?

Thanks a lot in advance for the help.

As noted over on Permies, you're going to need to file or grind back the overpeened portion as it's too thin to hold up in use. That should remove most of the warping in the process.
