Ignutz - I think you are dodging the question. For the moment, I'll grant that the word "blade" is not in the regulation but any fair minded person would agree that a "blade" as you used the word would be considered a "deadly weapon".
However, in fairness, you just have to provide a link to any regulation that mentions the existence of ANY external component (any short, naked or not) of the share structure of a company that is not part of the stock issued and outstanding and under the auspices of the Transfer Agent being grounds for nullifying the requirement to file under Rule 13a of the Exchange Act.
Take all the time you need. Thanks.
