I really don't know what that bar stock I mentioned above is, but it took two recip blades to make two cuts. Either they were junk blades (possible, HF), or it's some fairly hard stock.
If your recip is variable speed, select a slow setting.
It is the hi speed that heats up blades and dulls them rapidly.
I once cut a 12 disk in 1/4" mild and only used I blade on the jig saw.
But it was a proper steel cutting blade with correct TPI.
