This M-113B Finishing Fluting Stake is used to sharpen a flute  - generally one already made with the Fretz M-113A Starting Fluting Stake!  These two Fluting Stakes are sold separately yet designed to be used in progression; starting and refining flutes in bracelets. After you use the M-113A to flute a line, then you would switch to the M-113B to sharpen that flute. Compatible with Fretz H-1L and T-101 stake holders as well as the E-101 Extension Holder for a deeper reach (even though some holders are shown in the picture, all are sold separately). Fretz stakes are made from hardened 420 stainless steel with high polish working areas that protect your workpieces from accidental markings. Made in Vietnam.
