Described it before, I get the most enjoyment out of the Spyderco hobby when I limit the amount I own at any point in time to max. ten, backups included (and I only have Spyderco folders, except one BM Minigrip and some cheapos)
That means I focus on the very details I like even a bit more than other details, plus all of my knives can get really carried and used.
But it also means knives that I actually really liked and enjoyed had to go. But I never regret that, but somehow "positively remember" those and am happy I could try and experience them and "fine tune" more and more what I prefer in folders.
AND: It does NOT have to mean that I´ll never, ever come back to a model I already owned (and so buy it again).. For example I absolutely can think of getting in the mood once more for the great design of the Manix or the perfect ergos of the Millie I both once owned...
Top three going by pocket-time: Endura 4 in VG 10/Micarta-scales; Stretch 1 in VG 10; Endura 4 in HAP 40
