About the Maltby TS-4
The TS-4 is the blade of Maltby's Tour Series — a classic muscle-back profile released through The GolfWorks in 2023 that hides thoroughly modern internals. Each head is true billet-forged from 1025C carbon steel in a precision multi-step process; in the 3-iron through 8-iron a tungsten weight is co-forged low and toward the toe and CMC (Ceramic Matrix Composite), which Maltby pioneered in this iron, is positioned inside the head to fine-tune the centre of gravity and soften feel. That mix is why a traditional-looking blade rates 755 at the 6-iron on Maltby's MPF forgiveness scale, a figure normally seen from mid-size cavity backs. The face and sole are CNC-milled, the face with Maltby's multi-groove pattern, and lofts are modern for a blade — a 33-degree 7-iron and 45.5-degree pitching wedge across a 3-GW chart in pearl chrome, right hand only, on a universal hosel taking .370 parallel or .355 taper shafts. Sold as bare heads or built-to-spec custom sets, so the lengths below are The GolfWorks' published standard men's steel assembly lengths. A DBM black-finish version followed in 2025.

Frequently asked questions
What is the loft of a Maltby TS-4 7-iron?
The Maltby TS-4 7-iron has a loft of 33 degrees and a lie of 62.5 degrees, with 0.100 inches of offset and a 37-inch length on The GolfWorks' standard steel build.
Is the Maltby TS-4 a real blade?
In profile, yes — a classic muscle back at address. Internally it is unusually engineered: tungsten is co-forged into the low toe and CMC (Ceramic Matrix Composite) is placed inside the #3-#8 heads, giving it an MPF rating of 755, far above a conventional blade.
What is CMC in the Maltby TS-4?
Ceramic Matrix Composite — a lightweight material Maltby first used in the TS4, positioned inside the forged head alongside the tungsten to optimise the centre of gravity and enhance feel.
When was the Maltby TS-4 released?
In 2023 through The GolfWorks, per Maltby's own MPF ratings database; the DBM (Diamonized Black Metal) finish version followed in 2025, and both remain on sale.
Where it sits in the lineup
Introduced in 2023, the Maltby TS-4 is a current blade set in the Maltby range as of September 2026, with no replacement announced. New sets are built to the standard lofts, lies and lengths in the chart above, though a fitting can move any of them — so confirm the numbers on the order sheet. Used sets appear on eBay, and should be measured against this chart before buying.

- Lengths are from The GolfWorks' published Standard Lengths chart (golfworks.com/images/art/StdLengths.pdf, men's steel: 39.0-inch 3-iron through 35.5-inch PW and GW) because Maltby heads are sold component-style and built to order; playing lengths vary per build, hence confidence medium.
- Status check, 29 September 2026: confirmed as a current model with no replacement announced. TS4 forged iron heads listed for sale at GolfWorks (golfworks.com).
