Always carry dual fixed blades when working on or around machinery.
My grandfather always had a fixed blade on his hip when working on or around machinery. What he was taught growing up, and what he had taught me at that time. (I was 10 years old then.)
August 1965, we were tuning up the combine in preparation for maize harvesting season. His shirt sleeve unrolled enough to get caught in one of the chains/gears. He pulled his Kabar 1232 from his belt sheath, sliced his sleeve off and said -
"That's why you carry a fixed blade - you can never get a folder open in time in a situation like that."
"Popo, what if it had been your other arm?"
Brief pause....
Turns off tractor and says
"Let's go."
We drove the 3 miles into town to the Western Auto store, where he bought a Western L46-5, the closest thing they had in stock to a 1232. A couple of weeks later, after WA got more 1232s in stock, he got a second 1232 and then gave me the Western saying
"If you're smart enough to come up with that question, you're old enough to have a fixed blade."
Since then I have carried paired fixed blade except when legally prohibited from packing fixed blades (elementary and high school, college, AD in the Navy, college again, and a corporate job). During those periods, I still carried a folder in each front pocket. Back then, the PTB didn't care about political correctness. Students and teachers carried pocket knives to school. And we had rifles and shotguns on the gun racks in our pickup windows. (Well, I had a Ford Galaxy 500, so I had to mount mine in the turtle.



) For the corporate job, my fixed blades were riding on my EMS duty belt. The ONLY times I don't have paired fixed blades now is trips to the court house, police stations and schools. Still have the sheaths on, I just pull the blades and leave them in my vehicle.
