My saw blade opportunity

I got the blades this past weekend. There are 2 16" and 1 18" blades. They are a bit fatter than 1/8, but not quite 5/32 thick. They were the type of blades that had diamond along the edge. I have a few pics, but haven't got them uploaded yet. The guy who had them reported that he made 65 knives or so out of them with a bbq pit and motor oil. Yuck.... Anyhow, those blades would reportedly "hold an edge" through a deer or sometimes two. All in all, much less promising than I had hoped. Smaller than I wanted, and I figure the diamond blades are less likley to be good knife steel. I've been triple swamped at work and home both, so haven't messed with them formally yet. I've got a carbon steel batch on tap, and will likely do some experimental work with the saw steel at that time. I figure to try at least 1475 and 1550, (and maybe 1600) both with a 10 min or so soak at temp, and quench in 10 second oil.
 
Alright, folks, results are in. And.... The naysayers were right. I cut out a single blank. Sparked with some carbon, but not as good I'd hoped when compared to the steel from another blade that I had tested as 8670. Tried 1550 with a ten minute soak and it came out at 52 RC straight out of the quench. Just to be sure, I put an edge on it, which rolled. Wouldn't chip, even without a temper. Since I had other blades in the oven, and for the sake of science, I quenched it again from 1475. Got 53 that time. Looks like I've got some big paperweights with carbon in the .4-.5 range. Some of you "told me so", but I proved it for myself.
 
You could try a faster quench, although it probably won't make any difference. You've got the blade, might as well play with it.
 
Well, at least we can add this thread to the ones we will use when the next guy wants to make knives from diamond saw blade cores.
