edger blades

[zachackackattack]

What would the material be in lawn mower edger blades?

I saw them at the local hardware store for $4 and I know I can get 2 blades out of that.

known blade steel can be had as cheap as 4$ a lb and you will know what your working with

think about it a bit differently while they do have baulk buying power at the plant the blade was made they also have to mark the finished product up and cover all shipping
so how good a steel you think they are going to pay for 25 cents a pound maybe and you still dont know whats in the steel to help with you heat treating it

spend 20bucks with aldo and get soem 1084 shipped in you ll thank yourself later for not skimping on steel even to start

the cost of a knife is not in the steel and handle its in your time

also no matter how nice a knife looks if its not heat treated well it might as well be a letter opener
and no matter how ugly a good heat treat makes for a good user that will hold its edge

Zach, your quess is as good as mine. The only way to know for sure is to contact the company that made them (not necessarily who markets them) and see if they'll tell you what type of steel it is, and you'll likely have to wade through a few layers of employees before you find someone who even knows.

They may make a servicable knife, and they may not. Known steel is the best option, though experimenting with unknown steels doesn't hurt. The problem is you don't know if it will make a good knife, you don't know how to harden it, and you don't know how to temper it. You can figure all of these things out via experimentation, and you'll likely learn along the way. But you may waste $20 experimenting only to figure out it just isn't going to work.
