I received my first knife when I was 5 or 6. When he came home on leave in 1960 after serving a tour in Viet Nam, before being sent to Germany for four years, my uncle gave me the "Demo" knife, and the Ontario 499 "Jet Pilot Survival Knife" the Army had issued him when he enlisted. (I still haven't figured out why the Army issued him an Air Force knife. He was a Army grunt, not one of the CIA "Advisors")
I've had at least two or three knives in my pocket every day since. I've also had a Buck 110 or Old Timer 7OOR or 6OT on my belt every day since 1969. (8th grade)
From 1st or 2nd grade, the school district (and I suppose law enforcement) took it for granted that every boy in school had at least one pocket knife on him. (and that roughly 85% of the girls had one in their purse or pocket on the rare occasion one wore blue jeans or pants)
The teachers usually had one too. Well I remember the teacher asking if he or she could borrow a knife when they "forgot" theirs.
I was not the only one in second and third grade who brought their .22 rifle in for Show and Tell. (and it was not just the boy's that brought in their .22 rifle or pistol/revolver

)
In High School, you could tell when it was deer and waterfowl season from all the shotguns in the back windows of the pickup trucks (and rear side window of the SUV's) In Archery Season some had a bow and arrows.(compound bows had not been invented yet back then. At least no one I knew or who went to that school had one, if they were invented.)
Squirrel and rabbit seasons had a .22 or shotgun there.
If you were taking a Shop Class, you were expected to have a knife on you. Many had a Buck 110 on their belt. I did not take the class, (I already knew how to read and draw a blueprint) but I think you were expected to have a knife in Drafting Class, as well.
Times have certainly changed, and in IMHO, not for the "better".
I remember more than once during a job interview to present my pocket knife
The condition of your pocket knife was a determining factor in if you got the job or not.
No pocket knife ... You were untrustworthy; you did not get the job.
Dull Blades(s) or active red rust ... You did not take care of your tools. You did not get the job. (a patina was ok)
Broken or chipped blade(s) or broken tip(s):You did not use the right tool for the job/task at hand. You did not get the job.
Sharp blade(s) without broken tips or blade(s) chips and/or active red rust (again, a patina was O.K.) if you were qualified (education and/or experience), you got the job. Usually that same day. If you didn't have the education/experience, and they were training, you also got the job, again, usually on the same day as the interview.
From my experience, if I wasn't hired at the end of the interview, I didn't get the job, no matter what the job was.
When I had my own business (lawn care/grounds keeping, tree trimming/removal, firewood sales, lot clean-up, and fence building. Also did some minor demolition, and painted a "few" houses inside and out) I asked to see the applicant's pocket knife.
