1. A device for propelling a string comprising:
a body, wherein the body extends in a longitudinal direction;
a first wheel rotatable about a first axis;
a second wheel rotatable about a second axis parallel to the first axis, wherein at least one of the first wheel and the second wheel is a driven wheel;
a housing, wherein the housing is supported by the body and covers at least a portion of the first wheel and the second wheel;
a gap disposed between the first wheel and the second wheel, wherein the gap defines an axis that the string is propelled along and is parallel to the longitudinal direction along which the body extends; and
one or more string guides arranged to maintain a position of at least a portion of the string relative to the driven wheel and within the gap as the string is propelled;
wherein the one or more string guides urge the string toward an operational position within the gap and in contact with the driven wheel as a user moves the body in a direction parallel to the first axis.
