Nope. I mean...if you're going to use equipment of any kind you need to at least know how to take care of it. It couldn't be worse than cleaning a graphite furnace. :)
Anyone cut themselves on their ShootMoot knife yet? I did.
Reached into my purse to look at it while I was sitting on a bench at the bus stop (in the mall parking lot) waiting for Steve to get off the bus after dropping off the rental car. Didn't think I should pull it completely out of my purse, so I tried to pull it out while it was still in my purse. Put my pointer finger on one side and my thumb on the other side at the top of the sheath and pulled. The knife slide out and sliced open my thumb.
Oops! I won't do THAT again! I'll keep my fingers way low of the top of the sheath!
I actually forgot to bring any or my cleaning suppies anyway. Plus I figured we would not have the time. Really we did not dirty them up that bad. The number of rounds fired per gun was fairly low.
