i love to watch youtube. but one of the most frustrating things is something nearly every video omits... wheredo they get their source steel to make their blades?

I've seen several dudes carve up LARRRGE saw blades, sometimes 3 or 4 ft in diameter.. circular blades which allow them to make giant chinese style tuna knives or butcher knives .

Collective wisdom? any good sources?
 
Craigslist or offer up or eBay or go knocking around your local industrial areas if you’re so lucky to have them in your zip code.
 
used chainsaw bars are pretty easy to come by
 
I get most of mine from Alpha knife Supply. Great prices and you know what you you are getting
 
What the Count said. Just order the size you want from the supplier and you don't have to scrounge for questionable steel.

Don't get me wrong, I like filling around with scraps like leaf springs, jackhammer bits, railroad spikes, and rebar. But I KNOW that they are likely to be poor performers.

I made this karambit from the coil springs of of my buddies truck, but it was made as a birthday present for him. So it has sentimental meaning, and performance isn't the thing that really matters.

If you're going to make a giant knife for chopping up a 2000$ fish, you really should be making the very best knife you can make out of the very best materials you can.
 
There are a few places near me that buy and sell used building material and tools. There are always a bunch of old saw blades there.
 
If you're within driving distance of Longview, WA then check out the Northwest Blacksmith Association's swap meet (Swaptoberfest) the 3rd or 4th weekend in October.
Otherwise places that deal in scrap metal sometimes has them. If you're near Portland, you might want to check out Clackamas Steel.
If you are going to go down this road, make sure the teeth aren't carbide, because then the rest of the saw might not be hardenable.
 
I love old saw blades. The very best ones for knives are old two-man saws. About five or six feet of great 1080-1085 steel.
Be warry of other saw and tool steels. Just because it is "high carbon" doesn't make it a knife steel. Cast iron (and many other alloys) is high carbon and you can't make a knife out of it
