ROFLMAO!

Aside from the danger of unexpected electrical fun, those cut off bits of wire then to go flying at fairly high speed and can injure your eye(s), so wear safety glasses! Or the piece can get caught in carpet and thence into your foot when you step on it barefooted. This isn't theory, I've managed to do that. Not quite as much unfun as stepping on a 2N3055 pins up barefooted, I have that 2N3055 mounted on a nice stained oak board, with the blood still on the transistor case.

Needless to say there was a bright flash then darkness as the breaker opened.

I really shouldn't have giggled so hard, I think I hurt his feelings.
Heh.

Or grab the end bit that you're trimming off with a pair of pliers...

If you look at some datasheets for transistors, they specify a maximum "G" force for the part. That's what gets applied to the wires if you cut them, typically, and it can be quite high.

I have a small pair of medical forceps - they lock onto the wire end and stop it flying into orbit

I just got my "discover electricity" flashback thanks! I had already learned how to use a butter knife as a prying device and to connect antenna to tv. A butter knife is NOT a good tool to pry the plug out of the socket lol.BOOM.?

As I mentioned in a previous post, I've noticed an inordinate number of electronic enthusiasts also play guitar, or, God Have Mercy, banjos.

I've asked for photos of the fried outlet and plug but remembered Rod Elliot warned of this in an article on his web page.

Remember, the rest of the world uses some damn odd AC power connectors.

Now if that bit of string had landed inside his vacuum tube guitar amplifier, which was on, major fun [damage] might have happened.

But it still hurt.

I had a similar "accident" while working on a cuckoo clock. One set of chains dropped onto a plug not fully pushed into the socket. Needless to say I had to replace the set of chains.

Hemostats, yeah. I have two of those, one straight and one with an angled tip. They're very handy...
