Didn't know there was a knife thread here (although not suprised.) here's my camping knife. O1 tool steel (4mm). Cloth micarta handle, g10 liner and ss pins. Also has hardened window breaker.
I think its called a Spanish notch. I only use it as its easier to avoid scratching up the rest of the blade while sharpening, although I think it was originally as a blade catch for knife fighting. I won't be knife fighting.
