I had one several years ago. Its biggest advantages is being able to hold an edge for a very long time, and imperviousness to rusting, staining from acidic foods. The factory edge was somewhat obtuse and impossible for me to sharpen. As is, it provided no additional cutting benefits, yet less versatility than a comparable steel blade. Its usefulness is limited to light board contact / slicing soft foods (fruits, veggies, fish, etc.) It didnt do well harder texture foods (meats, root vegetables).
The blade is extremely brittle, so much so that it can shatter like glass if dropped, snap if torqued, chip on hard contact, etc. Despite delicate handling, I noticed the edge started chipping. I dont know if sending it back to the factory to grind out the chips would have helped, but it seemed as though the chips developed into some sort of stress / hairline fractures. Eventually causing the blade to snap into several pieces. Similar to how a small crack in a glass windshield or iced over pond expands over time.
