This might just be a cold, hard business decision. If the G10 UKPK isn't making them money you can't blame them for not making it any more. Besides there are still quite a few slipits to pick from, the Urban if you still want to pay a fortune, the FRN UKPK, the new Kiwi, the Bug/Honeybee/Grasshopper, Byrd Wings and the proposed new Byrd slipit currently in design, so it's not like they're not catering for us any more. Though I'll admit it's a shame to see such a landmark knife disappear from the catalogue.
