Not to move off topic too badly, but for the love of God, at least get a folder with a lock as a kid's first knife. Kids do stupid things with knives no matter how well you think you've taught them, and it's really easy for a non-locking blade to snap back on a child's finger.
Huh ... My first knife was a Demo knife, in 1961(?) 1962(?) ... My uncle gave it to me while on leave between Viet Nam and Germany. I was 6 or 7 at the time.
As far as I can remember, I never cut myself with it - or any other slipjoint or friction folder since.
Both my younger brothers received their (I'm the most ancient of us) first knives at a young age. Multi-blade slipjoints.
As far as I know, neither have amputated a finger or toe, or cut themselves with their knives. Slipjoint folder, lock back, or fixed blade.
Only one of my childhood friends ever amputated any parts. He was playing mumbly peg with his daddy's Ka-Bar (likely without his dad's permission to have the knife, or knowledge he had it, and removed 2 of his toes.
That friend was .... "strange" .... His mum told of the time he repeatedly burned his face with her lit cigarret (Pal Mal red) when she answered the phone in the other room, one afternoon ... she couldn't figure out why he was going "waa" (long pause) waa" (long pause) "waa" (long pause) until she saw him poking his face with her cigarette. ... He enjoyed whizzing up close on the hot wire of actvated electric cattle fences. ... He held the bag
at least 15 times "Snipe Hunting" overnight in the woods ...
His nickname in Jr. High was "Bullwinkle". We changed it to "Rocky" since between the two, Bullwinkle was the more intelligent, and had more common sense. (True. Neither were all that intelligent, and have about as much common sense of a door knob or a rock...)
I gave my nephew (with his parent's permission) his first few knives, starting with an Opinel Number 7, when he was 7, followed by a 1960's Ulster official BSA 4 blade Scout/Camp knife with a nice belt pouch and leather fob, as his "good knife" for Church, and going out with his folks, and a Buck 389 Canoe for his knock-around knife, when he was 9.
He hasn't cut himself with them yet, and yes, he does carry and use them.
He got his first lock back, a SK Blades "Lil' Jack" Buck 112 from me for his High School Graduation gift, at age 11.
(Yes. Smart kid, and home schooled. Aced every school district test to advance a grade, and to graduate. He 14 now, in college, and still getting straight "A's" in all his subjects. I don't know what his Major is. Something to do with advanced math/physics, I'm sure. Since Calculus, Physics, and Geometry were his favorite subjects in Highschool. Maybe some Engineering Major?)
