That's interesting, and raises the question of whether their customer support might be relied on for other things.
I own many Park tools (spanners, hex drivers, spoke wrenches etc), but only a few with moving parts: The PAW-12 crescent wrench, the CCP-2 dual 22mm (Campy/Shimano)/23mm (TA) square-taper crank extractor, and my bête noire, the CN-10 cable/housing cutter.
I bought this cutter brand-spanking new, and it's been terrible from day one. When the pivot bolt is tightened, it's too tight to close for the cut; when you loosen it enough for smooth travel, it leaves a ragged edge on the housing and pulls threads out of cables. There's no middle ground; there should obviously be some sort of thin Teflon washer (or even brass) between the two arms of the cutter, so that you get smooth travel but the arms are close enough for a clean cut. To me, this seems like a fatal design flaw. For decades, Felco and VAR have made cable cutters that work, and I've heard good things about Shimano's cutters; why would a brand that makes premium products design cutters with so much friction in the system that it doesn't perform the function for which it's designed?
I've never just thrown it out. I just stick it/throw it back into my toolbox, take it out forgetfully every six months to cut a housing, make a ghastly mess of the job, and get mad all over again. It's never occurred to me to phone Park and complain about the fact that their expensive cutter doesn't work at all.
