About the Honma T//World GS
GS stands for "Gain Speed": the 2021 T//World GS irons are Honma's game-improvement line, built to add clubhead and ball speed for average golfers. The 4- through 7-irons pair a 17-4 stainless body and internal tungsten with a cast AM355P L-Cup face over a flexible sole slot; the short irons are one-piece 17-4 castings. Lofts are modern but not extreme (29-degree 7-iron) and the stock build is graphite-first: Honma's Speedtuned 55 shaft at a light D0 swing weight, with N.S. Pro 950GH neo steel builds 0.375 inch shorter at D2. Honma numbers the scoring clubs — the 42-degree 10 is the pitching wedge and the 47-degree 11 the gap wedge, with a matching 56-degree sand wedge available. Lengths below are the Speedtuned 55 build.
Stock shafts
- Honma Speedtuned 55 — graphite · flexes: R, SR, S
- Nippon N.S. Pro 950GH neo — steel · flexes: R, S

What is the loft of a Honma T//World GS 7-iron?

What does GS stand for in Honma T//World GS?
Gain Speed. The line is built around adding clubhead and ball speed for average golfers, from the L-Cup cup face and flexible sole slots to the light 55-gram Speedtuned stock shaft and D0 swing weight.
Is the Honma T//World GS a game-improvement iron?
Yes. It replaced the XP-1 as Honma's game-improvement line: mid-size heads, internal tungsten and a cup face in the long and mid irons, and light graphite-first builds, sitting between the Tour Release players models and the ultra-light Beres range.
Production status
Introduced in 2021, the Honma T//World GS has no confirmed end date on file. It replaced the Honma T//World XP-1. LoftChart records a discontinuation year only where a source dates it, and none has been found for this set, so it may or may not still be in the Honma catalogue — check with Honma or a retailer before counting on a new set. Used sets appear on eBay, and should be measured against the chart above before buying, since irons are routinely bent from standard.
