Center Shaft Mallet

The KYOEI Center Shaft Mallet line, as we hold it, splits into two editions that share a head weight but part ways on neck geometry: the Center Shaft and the Slant Neck. Both carry the same bones, kyoeigolf.com reports a 365 g head and 2 degrees of bounce across each version, suggesting the line was built around a single mallet concept before branching into two ways of hanging the shaft off it.

The Center Shaft edition is the more fully documented of the two in our files. Kyoeigolf.com describes an SUS303 stainless steel face finished in Diamond Like Carbon black, paired with a custom KK Grip made by Garsen Golf and a genuine leather headcover with a magnetic close. That combination points to a maker leaning on outside partners, Garsen for the grip, for the finishing touches around a house-milled head.

The Slant Neck edition, by contrast, is defined in our record mainly by what changes at the hosel. Kyoeigolf.com lists 3 degrees of loft and 70 degrees of lie for this version, specs tied specifically to the neck swap rather than to the head itself, since bounce and head weight hold steady with the Center Shaft edition. Read together, the two releases look less like a redesign and more like a single mallet offered with a choice of neck, a common enough move for a maker refining how a head sits over the ball without touching what the ball feels at impact.
