ONLY" a straight, standard handle shape is doable on this model. The Randall shop is very specific in this regard. The only exception to this is the availability of using "stag" for handle material. By using stag you can get a "slightly" different feel/shape. Other than that, regardless of handle material from the shop, it will be fairly straight.
