The Dagger has been developed in co-operation with Dave Feldberg and is a deep dish beaded putter. Feldberg says it is comparable to a big bead Aviar, Wizard, Challenger, etc., but deeper with more float. The Zeroline Medium plastic really is the happy medium between Soft and Hard Zeroline. It has a firm feel with plenty of grip mixed right in. Zeroline Burst is a very unique looking plastic that has a mixture of two or more colors bursting from the center outward. All colors offered are the primary base color only and each one is entirely unique!
