The 2000 initially (bottom), but subsequently found the 2010 (top) which is apparently a limited edition. Both were extremely sharp out of the box, but the 2010 has a slight shorter blade, nicer handle and nicer sheath. The annoying thing about the 2000 sheath is that it has a loop of leather, so you can't just throw it in the dishwasher.
They feel a bit heavier in the handle than a Frosts Clipper, due to the longer tang, found this post on a knife forum that has an x-ray picture for comparison:
Anyway, a bit nicer and but a bit pricier than a Frosts Clipper, in my opinion.
Bought my 2000 here for £19.39 including p&p:
