I wear a heavy leather welding jacket and gloves, safety glasses, a face shield, and a couple layers of sweatshirts whenever I'm using one of these things. Even so, I have scars.

The last "good one" was some 20 years ago, using a cutoff wheel (fiber reinforced and everything) when removing sheetmetal in the gas tank support area of my then 14 year old son's '68 912 that we were converting to a 911. The disc shattered when it bound up on something. One big pie piece shard embedded in my left pectoral, right through all of those layers. I didn't really notice, except for getting warm down my crotch, then my leg.

"Hey Alex, can you grab me another disc? This one broke. Don't just stand there staring at me, grab me another disc."

Well, he was only staring because of the rapidly increasing pool of blood at my feet. Turns out that was what was keeping me "warm". Luckily, his mother (and my wife of now 37 years) is a nurse. I must not have been able to really hear him screaming like hell for her, because I was actually in the process of passing out. Never really felt a thing.

Long story short, she stopped the bleeding, got me to the ER, and I'm still here. Aren't you guys lucky?

So, yeah, these things are dangerous as designed. We can get really creative and make them even more so.
