comment How to diagnose an electrified refrigerator frame?
@skybreaker: That happened a lot and happened to me too. The shock strength greatly depends on other conditions - if you're staying on dry floor with dry slippers on your feet it's almost never strong enough to feel it yet a voltage indicator will light up no problem.

comment How to diagnose an electrified refrigerator frame?
@skybreaker: It depends. If the device has "double insulation" accompanied by a square inside a square pictogram somewhere in the spec - then it is guaranteed to work just fine without grounding. Power tools such as drills typically have that. Otherwise you have to ground the appliance to prevent being shocked when touching it. That's not specific to new aplliances - old stuff had to be grounded too but 50 years ago people didn't care about electric safety as much as they do now.

@skybreaker: I'd say "yes", most likely.

comment How to drill a minute hole on a wooden pendant without a drill?
I have to add that the black thick thing on one of the ends rotates freely so you can simply place the drill bit where you want to drill and then press it with your index finger and use the other fingers to rotate the rest of the thing. This makes drilling a straight neat hole much easier compared to holding the bit with pliers of needle file holder.

comment What type of bolt has a shoulder portion above and unthreaded region below threads?
@Jack: The chuck will not, but the file will. No matter how carefully you grind the threading will be damaged slightly and will need restoration.

comment What type of bolt has a shoulder portion above and unthreaded region below threads?
@Jack: I've read that carefully. I'm talking about the thread part that is closer to the head, not the part which will be cut off. Both are damaged when you grind and the former needs to be restored, otherwise how will you use the bolt?

comment What type of bolt has a shoulder portion above and unthreaded region below threads?
This will get the beginning of the thread between the bolt head and the smoothed part slightly damaged. To prevent that you drive a nut onto the thread and once grinding is complete you drive the nut away and it kind of restores the thread - see this diy.stackexchange.com/q/12465/807 for more details.
