For clarity's sake, for those who may not know, Broaching is done by a HUGE broaching machine (basically a 'one pass SHAVER' for iron/metal), it should be noted that it's impossible to 'apply broaching' any other way. So anything hand applied, or applied with a hand held machine is nothing more than 'fakery', an attempt to FOOL someone (a buyer or a judge). The reason people do this is to disguise rotary machine marks after cutting down the original stampings, so their RE-stamps might 'appear' to have been done after factory broaching.
