As daft as it may sound given the number of knives I have I am interested in "utility" in my knives....I have an aversion to "too many"....but at the same time it is not easy to give in to the thought that one may be a better knife than the others...then there is testing and figuring out what works best...then there is the "cost" of off loading some where you feel it sensible to thin things down...this leads to a reluctance to give some knives true use and a half way house appraisal of trying to determine matters from handling.
I also find that too many knives keeps quite a drain going on my finances....
But like many of us the "parting" with knives once they are in that "good to great" zone is hard to do...
