When I was 5 I found an old rusty Barlow out in the barn and ask my Dad if I could keep it.
Dad cleaned it up and removed all the rust, and taught me to sharpen it shaving sharp. He gave me a small pocket hone to go with it, and told me if he ever found it dull he would take it away. I’ve carried one ever since, and it is always scary sharp!
When I was in 4th grade the teacher needed a knife. All of us little boys whipped ours out. She took one and said this one is dull and gave it back. That kid got teased for weeks.
