Question for Knife Makers

[2B4Him]

We are in the picture framing business and use 12" saw blades on our double mitre saws. When there is no longer enough carbide on the tips to sharpen, we must buy new blades.
I hate just disposing of the old blades and was wondering if these are the type of metal from which knife makers would want to cut their blades.
I don't find any information in my files about what kind of metal is used - they are manufactured by Forrest Mfg. The only reference I find is to the 'C-4 Carbide' on the cutting tips.
Below is a picture of one after its last use.
Are these something knife makers would seek? If so, what kind of value is there?
Thanks.

P.S.: We once had a guy who would buy them from us to make rowels for custom spurs.

I would think they would be good for the knife makers.

using unknown steel is a crapshoot for making knives. For a guy that just wants to try making something for himself they may be ok but steel is about the cheapest part of making a knife, so to me it doesnt make sense to use unknown metals as opposed to quality steel

No this is not the preferred steel to use for a knife. The sawmill blades I use are from timber sawmills and are hardened all the way through and don't have carbide tips they just sharpen the steel teeth. Most of these have been phased out so all the ones I find are antiques. The new sawmill blades as well as circular saw blades are a softer steel so they will bend before breaking and don't have to be hard because they have the carbide that does the cutting.
