Too many to list em all, but here are a few.
"What would you say if I said I'd give ya $45 for this here knife?" (a $350 knife and marked as such).
Where do you buy your blades?
Where do you buy your handles?
Why is the blade two different colors? (polished blade with hamon)
What is this thing good for?
Can you introduce me to this Wheeler fella? I'd like to ask the guy that made these some questions.
You make knives? Are you some kind of psycho? (answer this question with maniacal laughter)
Wow, you sure must make good money making knives if you do it fulltime.
One of the most stupid statements ever....
I had a Bos heat-treated blade (back when I did only stock-removal) on my table at a gun show, that had been pounded through a factory blade (edge to edge). An Indian (native american) guy I actually used to fish with when I was a kid came up and looked at it. He then looked at all of my other knives and said, "These others wouldn't do that. They're not the same steel." I replied, "Yes they are, and yes they would."
We argued back and forth for about 10 minutes until finally he picked one of the other knives up, put it his close to his ear, and flicked it with his finger. He shook his head and said, "Nope, you can't fool an old Indian, these sound different, an Indian can hear good steel. Why are you going to stand here and try to bull-$hit people with these knives? I hope you didn't think you could get your lie past a good old Indian."
To this I was speechless. The gun dealer next to me looked at him and said rather loudly, "Oh yea, he must have forgot what f'n great metallurgists Indians all are." Of course this was pretty rude, but it was funny because of the ridiculous argument leading up to it.
