Not kidding. And I don't care about other people getting hurt, just me.
- A customer came into the shop and was fiddling with an x-acto. At the end of the conversation, he sticks it into the self-sealing mat. I gave him the look, he pulls it out and puts it back in the box. I found the broken tip of the blade while I was wiping the table down as it raked across the heel of my hand.
- The "shop dawg" (high school kid helping weed) sticks his foot in the trash can to mash down release paper to make more room. He pulls his foot out to find an x-acto knife stuck in his tennis shoe. --- The adhesive of the weeded vinyl caught the knife and was unknowingly thrown into that trash can.
- One co-worker was brushing the table with a small dust broom and launched an x-acto at another's sandal clad feet. --- she did an outstanding dance to avoid the projectile. ...it stuck in the carpet.
- An x-acto was stored point-up in one of those organizer things that fit in/around a 5 gallon bucket. Another co-worker found that with the tip of his finger as he reached around to spin the bucket looking for a tape measure.
So yeah, if there's two people in a room, and I think the other one might be a smidge more stupid, I think it's a good idea to have a policy about sharp pointy things.
Even beyond that, why would you not want to keep commonly used tools in a place where
everyone knows where to find them. It's a production table. If the knife isn't in your hand, it's in the way.
