Utensils, including forks with movable components, and associated systems and methods

An eating utensil, comprising:

• a first fork portion having a first set of tines;
• a first arm portion carrying the first fork portion, with the first fork portion movable relative to the first arm portion and removable from the first arm portion;
• a second fork portion have a second set of times;
• a second arm portion carrying the second fork portion, with the second fork portion movable relative to the second arm portion and removable from the second arm portion;
• a spring coupling the first and second arm portions and biasing the first and second arm portions to a default position;
• and
• a guide structure coupled to the first and second arm portions to guide arcuate motion of at least one of the first and second tools relative to the other, in a first direction away from the default position, and a second direction toward the default position, wherein in at least one position other than the default position, a tip of an innermost time of the first fork portion contacts a tip of an innermost tine of the second fork portion.

• a pivot pin pivotably coupling the first arm portion to the second arm portion;
• a guide body slideable along the first and second arm potions, the guide body have a guide slot with a first portion of the guide slot having a first width, and a second portion of the guide slot having a second width less than the first width;
• a guide stop carried by one of the first and second arm portions and positioned to restrict motion of the guide body along the at least one arm portion;
• and
• a guide pin carried by the other of the first and second arm portions and positioned to be received in the guide slot, wherein:
• the first and second arm portions are pivotable relative to each other about the pivot pin through a first angular range when the guide pin is positioned outside the guide slot;
• the first and second arm portions are pivotable relative to each other about the pivot pin through a second angular range less than the first angular range when the guide pin is positioned in the first portion of the guide slot;
• and wherein
• the first and second arm portions have a fixed angular orientation relative to each other when the guide pin is positioned in the second portion of the guide slot.
