Contrary to popular internet opinion, Palosanto recommends frequently stropping your beveler (how-to video coming soon!), but strongly discourages anyone without the proper professional equipment from attempting to sharpen their Palosanto beveler 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 create a beveler blade replacement program.  Size Bevel Width #00 0.2mm #00+ 0.3mm #0 0.4mm #0+ 0.5mm #1 0.7mm #1+ 1.0mm #2 1.2mm #3 1.5mm
