Hello, Chilly .Thanks!!!!! I don't have my Stanley Guide here right now, but I have never seen the handle offered separately. Yes , the handle and nut you could call an add-on, or accessory.I believe Stanley marketed the 9-3/4 as a set. Prongs of the handle are proprietary to the 9-1/2. With that being said, Stanley slightly changed the space between the prongs, still fits a 9-1/2, but you had to have a plane and handle from the same production era. Thanks to Patrick's Blood & Gore for the info. Regards, Lou
