Hand tool systems and devices and related methods

A hand tool system, comprising:

• a hand tool comprising:
• a first rigid member comprising a first lever and a first jaw;
• a second rigid member comprising a second lever and a second jaw;
• a pivot rotatingly coupling the first rigid member with the second rigid member;
• a coupler comprising a protrusion extending from a sidewall of one of the jaws;
• an attachment configured to selectively couple with the coupler, the attachment comprising a recess and a void;
• and
• an extension configured to couple with the coupler and with the attachment, the extension comprising:
• a hollow configured to couple with the protrusion;
• a projection configured to couple with the void;
• and
• a plurality of bends offsetting a portion of the attachment such that no straight line passing through terminal ends of the attachment would pass through the portion.

• a second rigid member comprising a second lever and a second jaw;
• a pivot rotatingly coupling the first rigid member with the second rigid member;
• and
• a protrusion extending from a sidewall of the first jaw and comprising a recess, recessed from a flat surface, forming a shape of half of a regular hexagon;
• wherein the protrusion is selectively manually removable from the first jaw and comprises a removable attachment;
• and
• wherein the removable attachment includes a clamp comprising:
• a pair of extensions distanced sufficiently from one another to receive the first jaw therebetween;
• and a tightening member configured to be rotated to secure the removable attachment to the first jaw.
