Then there is the old favorite stand-by method: Hacksaw! It only takes a minute or two of standing there tapping your foot while the Apprentice wails away at it.... (Really, it aint hard, and pretty quick. But why miss an opprotunity to say, "Come on - Move!" while I pour myself coffee.)


(Not for live work though, but I'm sure no one would be that silly, but threw the disclaimer here for stupid people.)
