Deviant Ollam "Mastering Master Keys" [HOPE Number 9]

A couple notes... I. master pins of size value 1 are actually semi-valid in Kwikset systems, because of the rather large bitting spacing for that style of lock II. zero-bitted depths are actually valid in other systems, Schlage locks for example. They aren't common, but they do not violate code standards. III. hand-filing is possible, but using a code cutter is often a much better plan if you have access to one! :-D
