We needed a sheath for our new WUSTHOF gourmet kitchen knife and what better way to do it than with a honeycomb patterned sheath? Turned out pretty good, I think if I were to do it again I'd make the hexagon smaller to keep fingers out of the sheath, but as-is it does the job well and locks into place after gently pushing the blade all the way into the sheath.  Turns out that it also works well with the CUTCO knife equivalent.
