“Knock” naming comes from the sound the cardholder makes when being placed/dropped onto the table of a restaurant or bar. The noticeable weight is a specific part of the design and is translated to sound serving as a hallmark of the object itself.

Can be carried however the wearer desires with the stainless steel top element allowing it to be attached to whatever the wearer see’s fit to increase its portability, safety, or convenience.
