Over the years, I've started collections, however the better knives in my collections have been Case, K-Bar, Buck and Bone factory knives.
I've always bought my sons knives, and for the past six Christmas's mostly cheaper knvies, but occasional Gerbers, My two oldest grandsons carry a 4" folder regularly, and I think they are Gerber Skelaton type.
Rarely in my life have I carried a pocket knife, as I don't like much in my pockets other than money. I may start carrying a clip-on in case something really crazy happened with my firearm. I do uses knives a lot, but most of that work is utility knives.
Still, I do manage to have a good little collection of hunting knives, again, nothing custom.
Speaking of Cutlery, my 19 year old son started selling CUTCO kitchen cutlery to work his way through college. At first I was skeptical until I was telling one of my seller's what Keenan was doing, she had a 40 year old set and had raised 5 kids. They still looked great. Then I found they were made in Olean, New York. I spent some time in Olean in my younger years and Learned Olean and not but 50 miles away Bradford, Pa. were both well known for cutlery. I even bought 4 knives for kitchen use ($300) and I love them.
Okay, I did get off topic, however I'm sure there are other merits to custom knives than just being hand made.
