N.B: The set consists of 4-PW (7 clubs).

✖️ Ultra thin face for metal-wood-like performance, resulting in faster ball speeds and much longer, higher-trajectory shots with increased stopping power.

✖️ Chrome plated finish for premium look and increased durability

Great looking irons

The 01t irons are as good looking as any I have ever played with. I am still in the trial stage and only using the 7 iron. My problem is I chose the KBS stiff steel shaft. Of course my choices were limited. This shaft is 126 grams so a bit heavy for me. I like a 102-104 gram stiff steel shaft. It isn’t the clubs fault. I am trying to decide whether to return and try the regular steel shaft (which they may or may not let me do) or keep them and replace the shafts. I also like their fast replies when I have asked questions. I still have time to work this out. Just not sure which route to take. Maybe they will let me swap these out for the regular shaft instead of crediting and recharging but I would be upset if they didn’t.

We don't cut costs in this department - we use the same shafts and grips as found in clubs priced 2-3x more.

First outing tonight for my new Caley O1Ts and they're fab! I feel like a kid with a new toy!

Superb set of irons - was looking at getting a set of p770s but thought I'd give these a punt and so glad I did. Actually prefer the look of these and feel amazing.
