The dealer who sold me my brush cutter wants me to buy an 8" Echo 20 tooth (or 22 tooth?) steel blade for cutting some saplings, but I've seen comments that they get dull very quickly. He's asking $25 for it. Today I saw a website, carbidebrushcutterblades, with carbide tipped blades they claim will last a lot longer. They cost less, too.
Is there any reason to go with the dealer's blade?
