Hey man, Don't knock the fun names for things.
I am a huge fan of "Percussive maintenance". It works well depending on what you are working on and why.
Its basically just "hit it until it works again". It works for a stupid amount of situations and things. Even electronics. @stupidbird
I have often deployed a BFH for planned Maintanence. Often my BFH needs oiling and if it that leads to planned replacement.
I am not familiar with BFH. Context matters and search engines are retarded. Is that something like BOFH? @stupidbird since I realize you don't get pinged on a edit. ^
I know it as a big fucking hammer, which is used to put delicate things in places said things do not fit.
