Topic tags/keywords: question

I have a few 10” saw blades, non-carbide that I will never use. What can I do with them? I was thinking of making scraper blades from them, but don’t know if the steel used is good enough for that. Does anyone know what type/grade of steel is used for saw blades?

I too have a collection of blades. I keep telling myself I will save them to use if I have to cut some “dirty” wood. But, I never do. Maybe there is a metallurgist out there who knows the make up of the steel.

First of all I think even the thinest would be to thick to use as cabinet scrapers but it could work as a stiff paint scraper type.
I’m curious as to how you intend to cut them; especially without over heating them in the process and removing the temper.

My son who shares my shop, has a plasma cutter. If I knew the material, I would be able to heat treat if necessary. Maybe a cabinet scraper is not such a good idea. Any ideas what I could make from them?

you can cut saw blades with a angle grinder with a “stainless” grade metal cut-off blade.
carving tools are the #2 choice with skinning/gutting sportsmen’s knives being #1.
lots of videos on the ole YouTube about repurposing circular saw blades .

Normally these blades are made from CV steel, Chrome Vanadium steel

Should be high carbon steel if they are any quality, a spark test will verify.

What is “scraper blades” ?
Cabinet scrapers are much thinner so you could bend them a bit.
But there is a lot more you can do from non-carbide ( <—- this is important) saw blades. Carbide tipped blades probably use much softer steel for the body and are not suitable for anything.
1. Ninja Throwing Stars
2. Dowel cutting plate.
3. Pry bar/Paint scrapers.
4. Resharpen.
5. Wall watch face.
6. Riving knives.
7. Corrugated metal cutters.
8. Disk sander.
9. Frisbee that keeps players much more focused than a regular plastic frisbee disk.

Some do, some don’t, you have to test each one.

Not sure if any of your blades would be suitable for these suggestions but it’s worth checking out.

Thanks all for the suggestions. I tend to procrastinate on implementing projects due to the multiple projects going on at any one time. Right now, that would be low on my priority list. When I’m doing a project, something always comes up to side track what I’m working on at the moment. The dangers of retirement. I need more time. Actually the saw blade thing came up as I was doing a project which was cleaning and organizing my shop. The saw blades which lay dormant for I don’t know how many years appeared while in the organizing process. I am presently going through withdrawal as I try to decide what to keep and what to send to the dump. For every 2 things I want to get rid of, one manages to survive to live another day. I am the ultimate hoarder. Anyone who saves scraps of wood knows what I mean. It has to be a disease. I realize it is not rational, but with guidance from my “organized” son, I will try to straighten myself out.

Walter Sorrells has a good spark testing video showing what the sparks actually look like here. Once you see this, the diagram Rick shared makes a lot more sense. After seeing this I went around testing every type of steel laying around in my shop, including a few of my cheaper tools.

If you are interested in knife making, there are tons of youtube videos where people use old saw blades for knives.

Good video Nathan.

Another tip, try annealing and re-hardening the steel from the sawblade because sometimes they use alloy steels that are very difficult to anneal or harden without a kiln.
