When you think about it, the word 'user' could be somewhat misleading. Might suggest somebody who uses knives in a very cavalier abusive fashion, not caring what the knife really looks like, its intended purpose, the quality of the steels or other materials. "It's a knife, I use it for whatever....." the kind of nightmare of a person you would never 'lend' a knife to else it comes back broken, covered in paint or been through a dishwasher...
We may be annoyed by the quality of table knives when dining out, might keep a knife with us for that purpose, but we don't have much attachment or feeling towards tableware, we just 'use' it, if we can
This is what most people feel about most knives, irrespective.
Talk of the old days or vintage years can be a misleading avenue to go down too. Most people in the past were not always that careful with their knives or interested in them, they were something to use, lots of people had little idea how to sharpen efficiently despite what we might like to tell ourselves. For the most part, people just had a knife or two knocking about the place or else had to use them in their work and they got 'used' used up very often and new ones had to be got in replacement-like electronics or batteries today?
Nevertheless, at all times certain people (us) have respected, revered and enjoyed knives, they likely had more than what they actually needed and might have arranged them into 'collections' ! Paradox being that in the past knives were used more; due to different times and occupations, you could buy them at a local source; BUT that local source was unlikely to be carrying knives from all over the country, just one or two marques. Currently, we have the internet to access knives, images and others' reflections on them en masse even if conventional knife/agricultural shops are rapidly becoming extinct. Thus we can have a global collection of knives given time, patience and money.
The terms collector/user are certainly not mutually exclusive but there is a difference in types of collector, their aims and approach. Those who think little of frequently spending large sums of money in pursuit of certain knives, who keep them locked away seldom to see daylight-living in dread of corrosion or corruption of their beauty
Others who relentlessly pursue 'rarity' or one pattern to the exclusion of all else, those who wish to compete with others to beat them to it or who never actually carry and cut things with their possessions. Compare this to the Enthusiast who is proud of their knives. Uses many as often as they can, takes good care of knives , enjoys exchanging knives and knife knowledge with others great & small, new and experienced without condescension. I think the vast majority of us here on this Forum and those who value GEC are in the latter more benign categories
Consider the extremely wealthy art-collector. Who gains most respect and contributes more to the appreciation of art & culture? The collector who spends a fortune to keep art hidden away in some deathly tomb or the connoisseur- enthusiast who donates works to public museums for the public to be able to experience and be inspired by? That is the knife collector and user or knife enthusiast if you like.
