after working on boats that fished all my life,I have sharpened many knifes...before stainless became popular it was easy with a stone.....with stainless I have found a file of the right coarseness does the best and fastest job....however I would not use it on a $100 knife..
got a 25 yr old Lansky stone set...it will sharpen a DULL (ie butter knife dull) in about 20 mins or so if u stay with it...Start out with course stone to cut and set edge angle, then finer stones to finish edge to razor sharp.
It has small bracket to hold knife solid so u can repeat the same stone angle with each stone..
Touch up on knife with good edge in about 5 mins...
