The Fretz M-133B Concave Fluting Finishing Stake is usually used to bring the basic concave flutes (such as those made with the M-133A Starting Stake) to a sharp point.   Although they are designed to be used in progression to flute concave bracelets and other forms; these items are sold separately.  Both are compatible with Fretz H-1L and T-101 stake holders as well as the E-101 Extension Holder for a deeper reach (holder in the picture is not included but is sold separately). All Fretz stakes are made from hardened 420 stainless steel with high polish working areas that protect your workpieces from accidental markings. Made in Vietnam.
