I found an old street sign. What kind of steel do you think it is? County says I can have it. About five years old. No rust.
 
Most of the ones i have seen are aluminum. If its actually stamped they are just some type of low quality tin type material likely. Any of the ones i have seen that are painted one side and not actually stamped with raised letters are just aluminum.
 
There's no reason that it should have any decent amount of carbon in it based on it's purpose/use. I'd hang it on the wall for decoration, or use it to make templates out of.
 
Wait, I changed my clock, but didn't know the calendar had rolled over to April 1 ,too. :eek:

It is just a sign, put it on the shop wall if you like it, use it for a dust pan, make an awning from it, ....whatever.......just don't use it for a knife.
 
It might be Infi... I heard of a rare run of them and some Elmax Stop signs a few years back. Sometimes the O will be faded more, that is always a sure sign.

Some Yield signs are 1095 but only the old rusty ones. The newer detour signs are surgical stainless.
 
I have an interstate mile marker 69 sign. Im pretty sure it is 154cm
 
I have a few signs and they are aluminum or steel, Neither of which are good for blades...but they work GREAT for small custom brackets. I've made several switch panels with this stuff and its great to work with,

Just to make sure everyone knows, this is sarcasm
 
Sarcasm? So the 1095 yield sign and D2 school zone sign i just stole were totally not worth it?
 
My best suggestion would be to get some 1084 from njsteelbaron. It will be very affordable, somewhat simple to heat treat and to work with.
 
Not very long ago I was using saw mill blades, then I ordered some good steel from Aldo, and EVERYTHING is easier... for the time and effort your would spend, its worth the extra few dollars, and you can make a better knife...win win situation!!
 
No need to recommend blade steels, guys.

Maybe he just needed some sheet metal to use around the shop?

No way anybody could think a road sign would make a decent blade...

Great point.

Most of the ones I have seen are Aluminum, I have no idea on the grade.
 
Johnny is probably laughing his butt off that so many people took his joke seriously....well, maybe he wasn't joking...and, maybe we weren't being serious either.
