The 3-D Offset IS my favorite Hammer ball of all time, though I doubt Hammer could replicate the core of that ball in a solid version.
Also, a flash back to the old Blade series. Back in the day.......I remember carrying an arsenal of several different Messengers and several different Blades. The Saw Blade, the Switch Blade and others and these balls were all very, very useful.
A ball with a similar reaction to that series of balls would be worth my while.
