Query: It was great at the beginning

I've been using this peeler for about 2.5 months. At the beginning it was the greatest peeler I've ever owned. I mean I could peel through veggie skins like butter but within a couple of months the peeler stopped becoming so sharp. Now I have a hard time peeling through ginger skins. This peeler was mostly use for potatoes and sometimes gingers. I didn't peel anything hard with it but it still lost it's sharpness.
