Blackjack Small vs Slick

[MW740]

I am looking at getting either the Blackjack Small or the Slick, but I need some more info. I would love to see a picture of these two blades next to each other that would show the differences in the construction of their tips and spine. Also, does any one know what the tang of these knives look like, and is there a gap between the tang and the guard or is is sealed as to not let liquid under the guard and handle? Any info would be appreciated.
