Sakata Lab Horn Putter (SL-003)

The Sakata Lab Horn, cataloged as the SL-003, reached the market in 2024 as part of Honma's Sakata Lab putter line. Firstcallgolf.com describes it as fitted with a crank neck, a diamond slit face design, and an "Original TPU Insert," paired with what the outlet calls a high MOI build. Both firstcallgolf.com and thestar.com.my report the same design intent for the head, describing it as suited to middle loft impact and straight putts, a point of agreement between the two sources even though neither carries the maker's own weight behind it.

Firstcallgolf.com also frames the putter's construction as methodically designed in-house for players wanting a wide sweet spot and resilience against miss-hits, a claim that reads as marketing language filtered through the outlet's own reporting rather than a specification the maker has confirmed directly. On price, the record shows a split: firstcallgolf.com lists 250.00 USD, while thestar.com.my lists RM1,320 MYR. Those are two different outlets reporting in two different currencies and there's no verified conversion tying them together here, so both figures stand as reported rather than reconciled.

Within the Sakata Lab Horn edition, the SL-003 is the only release the record holds for 2024. What's documented points to a mallet-style, high-MOI putter built around a crank neck and an insert-and-slit face combination, aimed by its own marketing at players hitting straight putts with a mid-loft strike. Everything else about how it plays sits with the reader and the putter, not with the catalog copy.
