HOW TO SHARPEN A 11 YEAR OLD CRAFTSMAN LAWNMOWER BLADE. 

That's true. Might have to file a little of the paint off to give it an edge.

True. You could also go that route or save yourself some money and just sharpen the blade.

Hi Tommy. Yes, you could. Easy to sharpen though. Eventually, you would want to replace the blade if damaged horribly. I made it eleven years and no issues. Cut fine. I just decided to sharpen my blade. OEM blades can be expensive at big box stores. My riding lawn mower 42inch deck is 60 dollars for a set. $$$$$

Not bad. A fair price for 2 blades. Many pro lawn companies just sharpen the blades themselves. Unless damaged. Get the most for your dollar that way. TYMM :)

You certainly can do that if you like. TYMM
