To answer your question, yes. Guys use everything from CNC to laser engravers and so on. This is a huge argument/debate I will not get into. On checkering there is always ways to tell. As far as bit marks and other details that just depends on the maker and his preferred methods and the way he likes his calls to be finished. One way or another a computer, machine, whatever cannot and will not EVER spit out a hen turkey. Without proper tuning by the ear of someone who knows what a hen sounds like then all you have is a pretty wooden paperweight.
