I was just sharpening my upgraded 201 and looked at the date on it, it says 2012 but I think I got it in January 2013.
So 4 years later it has not missed a beat, never been in the repairers, unlike my 200s which only seemed to last a couple of years at best, now, I'll confess I alternate it with another 201, from 2013 which is post upgrade and has also never been in the repairers (apart from a broken handle, my fault) but still, a bloody brilliant pice of engineering.
