This B-5 stake is distinguished by its rolled edge and flat top allowing you to hammer out bezels without tedious cutting and mitering.   Use pliers to shape the bezel sheet around the stone as closely as possible, then use the stakes to gradually stretch the sheet to match the corresponding curves and angles of the stone for a perfect custom fit. Made of hardened 420 stainless steel. Use with H-1 or VH-1 stake holders (sold separately).  Head measurement: 80x11.5mm.  Overall measurement: 3-1/4"L x 2-1/2"H. Made in Vietnam.
