Yea I don't think the OP called anyone out. Sounds like a genuine question he was asking. He was just asking if anyone thought there was a length where a person would start took look ridiculous. That said, i dont think there is a particular length alone that would be ridiculous. Though there would be some cases where I might think inappropriate. And some other cases where the type of knife combined with the person carrying it look particularly dumb. One instance i could think of was at the mall where I saw an otherwise harmless guy carrying two fixed blades on his belt, one on each side. What i found funny was that they weren't parallel to his leg but had the handles angled away from him so that they were in a "v" from his body on both sides. And i mean in such a way so that he could draw to kill or something. I couldnt identify the blades and they did not look particularly impressive in any way. I thought he looked like a complete tool
Except for the odd handle arrangement, you might have been referring to me.
I carry paired Kabar 125Xs every day, 1 at 4 and the other at 8. That's for public carry, off the farm. Around the farm it's a BK9 and either a Kabar 1217, an Ontario machete, or a BK20, depending on what I'm doing at the time.
Has absolutely nothing to do with self defense or compensation issues. If you need to suddenly cut something with your left hand, and your only fixed blade is on the right, you are screwed, or vice versa, re: L/R carry.
In 1965, my grandfather's shirt sleeve got caught in a combine drive chain. He pulled his right hip carry Kabar 1232 and cut his sleeve off before his arm was dragged into the gears.
He looked at me and said
"That's why you carry a fixed blade - you can't get a folder out and opened fast enough."
When I asked him
"What if it had been you're other arm?"
He looked at me a little funny, turned of the equipment and said
"Let's go."
We went to town and he bought a Western L46-5 as the Western Auto store was out of 1232s. When 1232s were back in stock, he got a second one and gave me the Western.
He said
"If you're smart enough to come up with that question, you're old enough to have a fixed blade."
I was 10 years old and that started me down the road of fixed blade (and other knife) accumulation. 52 years later, I am just now reaching 3k+ fixed blades of different types.
Old Texas farmer's proverb - It is better to carry paired fixed blades and not need them than it is to have no fixed blades and need one.
