I once received space & depth books from a well known locksmith related magazine free with my subscription. Thats been a long, long time.
The best source I have seen lately is our operational manual for the ITL code cutter.
Another good source would be a Framon code cutter manual.
Same with an HPC code cutter.
Nothing is foolproof to a talented fool. Wisdom is not just in determining how to do something, but also includes determining whether it should be done at all.
