Diamond Saw Blades Core Material?

Being part of a concrete cutting company grants me access to used diamond blades that may offer potential in crafting a knife. Observing that these blades can rust, I suspect they are made from high carbon steel, indicating they possess a hardness suitable for enduring persistent friction from cutting. I'm interested in understanding the specific type of steel utilized in the blanks of these blades. Do you think they require heat treatment? Has anyone here ventured into creating a fixed blade from this material?

What thickness? I think they used to use L6 for wood saw blades. Not sure if they'd use L6 with diamonds for concrete, but I wouldn't doubt it. If you have a small piece, you can send it to me, and I'll Rockwell test it at work.

I estimate the thickness to be around .187 inches, as the diamond segments measure .250 inches and are broader than the blank. I will prepare a section for testing; how large of a piece would you need?

A 1x1 piece is fine, or a little bigger. I can test different spots to check for hardness uniformity. Shoot me a PM and I'll give you my address.

In my experience working with a granite company, I've had similar access to various diamond blades. The smaller grinder blades might differ from the massive blades used on bridge saws, which have a middle layer that I once attempted to use for making a throwing knife. The blade failed after just a few throws, highlighting the challenges with these materials.

Finding the manufacturer and reaching out to them would be a wise step. They would certainly know the specifics since they produce the blades.

That’s a good plan; I will connect with a salesperson I know, as we typically do not conduct direct factory dealings—most of these are produced in South Korea, especially the diamond segments. Our standard sizes range between 14" to 36".
