The F1 grade stuff is flexible and cloth-like. From what I gather, the stuff Dave offered is sold as rock hard felt sheets. If you search the web I think you will see it is expensive and typically offered in large dimensions and not in 1/8" thickness. Dave indicates that the hard stuff worked much better for stropping. Marko (tsourkanknives.com) I believe offers a similar grade felt which you can buy mounted or magnetic backed for use with a base such as a DMT diamond plate.
