Contrary to popular internet opinion, Palosanto recommends frequently stropping your French skiver, but strongly discourages anyone without the proper professional equipment from attempting to sharpen their Palosanto French skiver blade.  Palosanto does offer complementary blade sharpening with every tool they make, but the downtime and/or shipping cost between Korea is not feasible for many makers.  

As an alternative, DLS and Palosanto have worked together to offer replacement blades for your French skiver.  Using a 1.5mm allen wrench, loosen the set screws in the brass ferrule, slide the old blade out, slide the new one in, and tighten the set screws.

French skiver handles are made to fit any size Palosanto French skiver blades.  So, you could purchase different size blades and swap them out in your handle whenever you need.
