The new Geotech offerings look great, both the driver heads and the forged iron heads. I noticed the Quelot heads are s15c steel, which is a bit unusual. I remember seing some wedges from George Spirits that are s10c even, but that's about it. Is there an advantage using s15c in the Geotech Quelot heads? This being Geotech's premium brand and all. It also states they are 'hand forged' but that must be incorrect?

question also on the s15. some time ago there was a lot of squawk about scratch golf saying they are using s15 steel and the response here was that it was either inferior or not being ideal for golf irons. so then why would you promote this is the quelot?

I thinkt Scratch claimed s18c? Not sure though.

No advantage, it's more marketing than anything else. The heat treatment will determine softness versus the amount of carbon in the steel.

Quite a few companies have used S15C in the past. There is no such thing as S18C, Scratch has been very misleading about that.

Thanks for the info. And, yes, from what I remember (could be wrong) IF there was such a thing as s18c then s15c (and for sure 20 and 25) would be a better material? Plus the "softest forging" claim would still be untrue since some use s10c..Which anyway, like you point out, is less important than the heat treatment?

It's not that its less important than the material. The heat treatment aka annealing process refines the structure, softens, and changes the properties of the material. Most factories don't mess with this so much but places like Endo have the ability to make the same iron in a variety of different feels.

thanks for the info, chris. wasn't aware of the metal properties and how the treatments could affect the heads. in your opinion, what head that endo forges(regardless of brand) does have the softest feel then?
