Craz-E

The Craz-E line opens in 2007 as the Karsten Series CRAZ-E, one of the heel-shafted mallets in that release alongside the return of the Anser. Our review of that Karsten Series putter didn't focus on the Craz-E head directly, but it laid out the family's thinking that year, an elastomer insert set into the cavity to soften the strike while keeping a steel-faced response, with weight pulled to the perimeter for added forgiveness. Golfbluebook.com's reporting on the 2007 Craz-E lines up with that approach, listing the same elastomer insert in the cavity, a steel face, perimeter weighting for MOI, and a slight bend offset, at an MSRP of $130.00.

The name then spreads sideways rather than forward for a stretch. Golfbusinessnews.com's coverage describes a Craz-E built around an optigraphic alignment system for a longer line of sight and a low CG pulled back from the face for a straighter roll, and that same reporting shows the name splitting into a small family of variants, the B, the C, the H, and the L, each shipping on its own schedule and its own price. The B carried an MSRP of £140 (€219) and was, per that reporting, already shipping; the C and H were both listed at £125 (€185), with the H shipping and the C set to begin on the 15th of November; the L, built as a long putter at 48 inches with a 10 degree lie, matched the B's £140 (€219) and was also reported as shipping. Golfbusinessnews.com credited the line with an 8 percent market share in its first five months, calling that "a notable feat," which is one publication's read on the Craz-E's commercial run rather than a settled figure.

By 2014 the name resurfaces as the Scottsdale TR Craz-E, now built around a telescoping, wrench-adjustable shaft that golfalot.com reports could rotate to set the face open or closed, tested at an adjusted length of 36.5 inches. Golfalot.com came away impressed, writing "Ultimately, I was impressed by the Craz-E," and praising its consistent feel across toe and heel strikes and its distance control on longer putts, though the same review flagged that the adjustment collar adds weight near the hands and that the shape won't suit every eye.

The 2017 Sigma G Craz-E marks another materials shift, with mygolfway.com reporting a 6061 aerospace-grade aluminium face paired with a Pebax elastomer insert, a 370 gram head, a Platinum finish, adjustable lie of plus or minus 2 degrees, and PP60 and PP62 Ping Pistol tapered grip options. A later Karsten 1959 Craz-E ties the name back to that earlier Karsten branding, per golfmonthly.com's listing of it under the Karsten 1959 series. Across nearly two decades and multiple letter-suffixed variants, the Craz-E name has attached itself to a heel-shafted mallet shape more than to any one fixed specification, changing face material, insert, and adjustability with each era while keeping the name intact.
