The main gripping area consists of only 3 ring cuts. By making the top and bottom without any grooves, this emphasizes the 3 ring cut to allow the player to firmly grip the barrel.
By further adding taper near the back end of the barrel, this assists in providing support during the throw. 4 ring cuts for the index finger and 3 ring cuts for the middle finger are placed on this barrel. The cut placement on this barrel consists of only where the fingers actually make contact with the barrel.
The 20g version of the latest Yuki Yamada model is one that he actually uses during warm up and for adjustment purposes when he feels his darts are dipping.
