An absolutely beautiful 63-layer damascus steel, over a special hard alloy blade core (HRC 60), for superb performance, sharpness, and spectacular good looks. This standard 6.9" (175mm) santoku shape and length is perfect for home or pro use, and the handle has a great size and very angular profile, for excellent comfort and control. The handle is also very nicely polished and finished in a semi-transluscent blue/black, complementing the overall great looks of this very special knife. And yes, it has an AMAZING factory edge that is spectacularly sharp. I'd recommend the fine ceramic hone for regular/daily maintenance of the edge. As with any knife, use the hone regularly and you'll keep the edge in good shape for a LONG time before you need to think about doing any serious sharpening or real grinding and refinishing of the edge.
NOTE: This knife is sharpened in the traditional Japanese style, that is, almost entirely on the right side, which means it's not really suitable for left-handed use. And when you maintain it, you should concentrate your sharpening and honing efforts on the right side of the blade. Of course if you sharpen both sides you're free to change the edge to a more symmetrical bevel, or even to a left-handed bevel (this is also more easily accomplished quickly and easily if you have a good coarse sharpening stone). Or you can bring it to a professional knife sharpening service (a GOOD one that you trust!) who can re-grind the edge however you'd like. A symmetrical right/left bevel (good for left or right hand use) in my opinion really won't diminish the performance much if you maintain it, so that's also a good option if you're left-handed.
