gimme a bit and I'll get a pic of just the piece of steel that I haven't ground into a blank yet. It heats up easily with my grinder but for the thinness it's pretty sturdy

What more info is needed? I seriously want to know how to find out or if someone else can tell.

Looks like S3V, does it taste tangy?

Just kidding... is that a planer or lawnmower blade?
 
It is most likely mild steel, knife steel is an extremely rare find.

I'd consider buying some 1084 or another known steel. Nice looking grinding and profile! :cool:
 
There is Very little info tat we can go on based on the photos. Considering that shape could be made from melted down soup cans to being cut from a high alloy piece.

The only thing so would suggest would be to cut a piece off and heat it until it is a few shades over non magnetic and quench it in water and then try to break the coupon and inspect the insides.

You can also try to grind it and inspect the sparks coming off and try to get a read from them.

At best, both of these methods will only give you a general direction to look, and give an indicator as to whether it has enough carbon to harden at all.

Or, you could take the pricey route and send it off for testing and end up with a chemical breakdown of it and come back.
Once you have that, others can let you know the HT protocol and what it's ideal usage and hrc range would be.

Good luck.



I was thinking it could be an Edger blade. Those are normally dull, have a hole in the center for mounting and are sold in bulk since most landscape companies go through a few each summer per machine.

If that is the case, it is Very likely to be of little value as a knife steel since it will be low carbon and won't harden up.

My second knife. I hit a 2 by 4 with it then hit the top of knife with hammer until the 2 by 4 was split and it was still almost shaving sharp.
 
To tell you what kind of steel that is would be like taking a apple. Slicing the skin off, then take a slice off the "meat" of the apple and asking what kind of a apple it is. At that stage we could only guess it's a apple because that's what you said it was, BUT it could be a pear too!
 
That looks like an lawn edger blade from HD Maybe 1050 at best
After you read all the stickies at the top what did your spark test show?
 
I am going to close this thread because it will likely go South rapidly from here.

Final comments:
The steel is unknown. From the look of it, it is a mild steel that comes pre-drilled for bracing and straps. It won't make a good knife ... it probably won't even make a bad knife.

You need steel that has sufficient carbon to harden. Most folks buy it from a knifemakers supplier, or from Aldo Bruno - The New Jersey Steel Baron.

Reading the stickies would be a good idea. Filling pout your profile would be a second good idea.
