I don't know how long caulk guns like this one have been around, but man is it cool that someone invented a way to add these features. The things I used to come up with to puncture a hold in the tube were crazy, and how much time did I spend trying to find the piece of cap that would go flying after cutting it off? Maybe I'm just easily impressed, but these simple features are awesome.
