Do you know the names of different tools or do you call them "whats a ma-call-it?

I like to know the names of different tools, saws, screw types, etc. I'm always asking dh what is this or what is that.

What do you do?

I often know the correct name for them and he doesn't know what I'm talking about..... Many debates have sprung from this....
I am right 99.9% of the time... Now if I made up a name for it, he'd just take my word for it........:D

I usually know what tools are what too! :D
