The handle rotational motion of the HDBW is accomplished by using the user's forearm muscles as opposed to their wrist muscles. This substantially reduces risk of injury to the user's wrist.
The yarn guide arm can be swiveled 180 degrees to allow for 5 different angles at which the yarn supply can be positioned relative to the ball winder.
Made of Maple hardwood, 10mm and 3/8" diameter steel shafts, and commercial grade, heavy duty Swiss gears.
Designed and manufactured in the USA with 1 year warranty. This will be the last ball winder you will need to buy---it's that good!
