Please refrain from negotiating prices. I purchased this as a new steel and have used it for test cutting and sharpening on a whetstone. *Only the cutting edge has been used; the flat part is clean.* It is said to contain tungsten and other elements in addition to VG10, and it gives the impression of holding an edge longer than VG10. VG10 is already a well-balanced steel, but I believe this is a more refined steel. Combined with the shape, the sharpness is outstanding.
