These unique Puppy Hammer nodes are designed for the most demanding artist. They use a small neck node, to minimize weight in the middle of the hammer and allow your hand to slide past them easier in dart mode. The hand nodes have a filleted groove to help easily grip the nodes when sliding between modes.
Note - if you are getting these for Fire work, keep in mind that dark colors are hard to see at night (could be a plus, might be a negative).
