NOT the whole pruner...this is the replacement blade for the Original Felco 2 Pruner. You don't have to do this really often unless you use your Felcos professionally. Usually, a really good sharpening will do the trick. But, if you have sharpened as much as you can and the blade is finally getting thin, replace it. This is why you pay the big bucks for the Felcos...every part is replaceable.
