This forum has really been an inspiration to me.

Does anyone know a really cool use for 3 or 4 hundred 10" 40 tooth carbide saw blades? These were rated for cutting wood and aluminum. Most of them are only slightly dull. I can't throw them away.

Seriously, if you have enough slightly dull blades there to make setting up an automatic sharpening machine and letting it run all day. It might run $3 to $5 a piece to sharpen the old blades rather than $35 to $50 each to replace them. And the savingsd add up if you can sharpen them three or four times before they start shedding teeth and need to be tossed.

The ONLY drawback I can see is that the cut diameter will be a few thousandths smaller after each sharpening - but if you need that kind of precision, there will be a way to zero out the saw to the exact cut depth of the installed blade anyway.

Where it becomes more of a financially inviable problem is when you have to start brazing on new saw teeth at $3 to $5 each where they've popped off, then another $5 sharpening the blade to get the new teeth down to the same size as the rest of the saw.

It's not that hard to make that choice either - On a $200 Metals cutting Cold Saw blade or a $300 36" sawmill size blade you have the sharpening service replace the missing teeth, on a $12 hardware store cheapie saw you toss the whole thing.

Some contractor will glom onto them and you'll have some pocket change to build something REALLY nice.

Since the blades are meant for wood or aluminum you should be able to stack them tight and grind aluminum with them. Not sure what you can do with ground aluminum other than pyrotechnics.

Beyond that I think I remember somebody using saw blades for knife blanks but I doubt the steel is ideal for that.

I really can't think of much else other than an art project.

A long time ago, I saw plans for making tables out of a single piece of wood, by cutting kerfs into the wood so you could bend it.

That was the point.
I figured you're working at a Furniture Factory that has semi-automated gang saws for mass production, and they just change the blades on all the machines every two weeks whether they really need to be changed or not. That's the safest logical explanation for having a huge stack of slightly used blades around.

My recommendation still holds, go through and toss the ones missing teeth into another pile, and send the good ones out for resharpening. Reduce, Reuse, Recycle.

Then you could reuse them a few times (till they throw a tooth or get too small) and save the company a ton, or pack them into 1-Dozen lots and E-Bay them off - put the money into the company Beer and Picnic fund. Or yours if they give them to you.
