oiling is important one in a while denn, it doesn't have to be done every time you wash you knife as todays steels are quite stainless & all
but everynow & then it's important for cleaning little things that stick & for smoothing the action (thus reducing friction & wear)
nah, i'll stick with my opinion
, with my cleaning-method (regularly with hot water, and i'm talking HOT water here, as in steam and painful on the hands...
the first thing that always bothers me when i get a new knife, is the yellow/greenish goo that keeps coming out of the pivot area, even after 2 dozen swipes to get rid of it, i hate it.
i think if you thoroughly rinse your pivots with hot water on a regular basis, you don't need lube. i only use oil on automatics, because those are the only knives that rely heavily upon it, but i still don't like oily goo on my blade, especially when using my knife to prepare fruits and such.
no oil for me, thank you very much.....
