Also, Jackson charges more for the Matrix series than the titanium coated Apex series, and some of the Matrix blades (like Supremes) are tapered too, so I don't know if there is meant to be an improvement over Matrix blades.
Also,
http://www.tibeachtech.com/history.htm says titanium beach is working on the Pegasis blades, but that they have not been "certified" by USFSA or the ISU. It does not give details as to whether the entire blade is titanium, though it sounds like they might be. It also sounds like they have not sold many.
Additional details:
http://www.tibeachtech.com/products.htmAt $1200-$1500, they are not cheap.
It's also possible their page is out of date, since part of their pages was updated in 1999, and it seems like that is enough time to become better known. In fact, I didn't succeed in emailing them.
If so, maybe no one makes completely titanium figure skating blades...
So ignore what I said about titanium.
