The question is a bit confusing. The stock shafts are listed on the website and that is what you will find in most retail locations. Those are all graphite. If you have the club special ordered through a retailer or your local pro shop, you can get any shaft you want including a KBS steel shaft. Some shafts have additional up-charge to produce but many can be put together at the same price as the shelf models in the stores so don't assume you have to settle for what you see at a big box store.

The KSB Tour shaft listed in the Hybrid & Utility Shafts section of the Custom Options booklet looks like it is steel given the listed shaft weights are R - 120g, S - 130g & X - 133g. Refer to the Custom Options booklet for additional information or the KBS website, links for both are listed below.
