I do not have a picture, but we used to get sheet cakes from a Giant Eagle for office birthdays etc. It had a cutting diagram on the side of the box...... Now you just can't fix stupid......
of battery acid with "do not drink " printed on the side. But then when I was a kid I used to pick a good sized piece of grass and put it in between my thumbs to blow thru for a duck call and cut my lips. Again and again............
There actually is a legitimate reason for that warning. The screwdriver bits that Brownell's sells are very hard - to the point they can and will snap off, sending pieces flying. Brownell's claims they are designed that way so the blade will beak before the screw is damaged. I don't know if they still do, but they used to replace them for free.
You can ask me how I know this but I ain't gonna tell you...
