Do I sound like a guy who would shoot a full can of beer, even if was a shítty brand
I prefer Hertog Jan, Palm, or Grolsch however

It's not the best Dutch beer but definitely the easiest to get hold of outside of Holland.
If you polish the thing, and make a brass collar it will look very nice.
Yeah, cap for the schrader, strip down and polish the blade... but you know me and aesthetics.
That looks pretty cool, but in america I know spring powered ballistic knives are illegal and can carry jail time. My guess would be pneumatic ones as well. Since I have no idea what country you are in.
Sounds a bit silly in a country where you can freely buy a semi-automatic rifle, unless they are considered to be in the same category as a suppressor - but even so, this is a horrible choice of weapon, you only get one shot and unless you have spare blades to hand, you're just left with a handle.
For scale, here it is with my 7 inch blade spec plus - if it didn't have sentimental value, I would be thinking of scaling up and launching the latter knife...
