Craftsman 9" Replacement Reversible Edger Blade —
The blade is a normal wear part and is not expected to last forever. The less you hit hard objects such as concrete the longer it will last. The average cost of $5.50 each blade is very reasonable. The 3 blade design is better than 2 and does not cease up like a 2 blade does. I agree not stocking replacement parts in Sears stores is disappointing and makes you feel like the product is not being supported.
