The present invention, in some embodiments thereof, relates to an improvement of string/material winding devices and mechanisms. Accordingly, a device is provided comprising of an axially rotatable spooler with shoulders defining a length between them to engage a roll of string/material, wherein the spooler comprises one end with a bevel gear mechanism defined inside the device's housing. Further, a second bevel gear mechanism is provided in the housing to engage the axially rotatable spooler's bevel gear mechanism. Further in the housing is a one-way spur gear rotatable by a rack actioned by a handle, wherein the rotary motion of the said spur gear is translated to the second bevel gear which causes an axial rotation of the spooler to wind or unwind a string/line. According to one embodiment, the one-way spur gear, rack and handle from a ratchet mechanism.
