I honestly have mine professionally sharpened a couple times a year. It’s only about $20 so not too terrible. Look in the phone book for sharpening. Or you can alot of times take them to the nearest Home Improvement store, they sharpen things like shovels and gardening tools all the time. I would recommend finding a good sharpener though instead. Alot of times you can make deals with them that they will come once a month for a much lower price.
