Well, I will offer a slightly different point of view....
I have basically 3 types of knives that I own....
I have ones I use whenever, for whatever on a daily basis, that I do not see as even in my "collection"... true EDC and while I don't intentional abuse them I see them as 100% tools (like my spyderco mannix 2, PM-2, BM-940)
Then I have more expensive knifes that I carry less frequently and tend to limit to only lighter use (only cutting tasks...no prying, turning screws, chopping, etc) These would include my Sebenza's, my FF's, my Hoback, some of my Shiro's, and one of my Rocksteads... These are part of my "collection" , but treated with much extra care/respect.
Last I have my true, pure "collection" pieces that get no serious use and are not typically carried (dress Lamberts, Thorburns, Voorhies, Martins, Fishers, Williams, etc. etc)
I for one would be sick it I damaged any of the knives I own as actual collection pieces. I am not wealthy enough to view a $1500 and up (way up! haha) knife as any sort of actual user...
