Couple of things... my King Cutter (current model) actually is etched with the boker name on the shank.

Also, I think the blurb is actually from Boker's marketing material. I've seen it on other seller's sites.

Boker's own site says this about the King Cutter:
Same as model 140501, but with the popular “Spanish point.” The so called tapered hollow point of this blade can only be ground by highly experienced experts. Blade size: Same as model 140501, but with the popular “Spanish point.” The so called tapered hollow point of this blade can only be ground by highly experienced experts. Blade size: 5/8“. 5/8“.
