Fretz M-133A Starting Concave Fluting Stake

The Fretz M-133A Starting Concave Fluting Stake is purpose-built for creating handcrafted flutes on concave bracelets and other curved metal forms. Designed as the first step in a two-stake fluting process, the M-133A features a concave profile with a slightly rounded ridge and two distinctly angled concave planes on either side.

Side 1 is steeper and is used when flutes are positioned close together or when a wide, deep flute is desired. Side 2 offers a more gradual angle suited for general fluting when a subtle, refined flute is the goal. When used with a round crosspein hammer — such as the Fretz HMR-8 Rounded Narrow Crosspein or the HMR-9 Rounded Wide Crosspein — the stake produces a shimmering, planished surface finish.

This stake is designed to be used after the project has been formed on the concave Fretz M-104 Stake (part no. 112.734). The M-133A works in combination with the M-133B to complete the fluting process on concave surfaces.

How to Use

1. Draw the desired flute lines on the formed concave piece using a sharp marker pen.
2. Place the drawn line directly on the stake's ridge line.
3. Planish the metal just below the pen line, driving the metal down toward the stake while maintaining a slight air pocket between the metal and the stake surface.
4. Repeat on both sides of each drawn line until flutes are roughed out across the full surface of the project.

Features

• Concave profile with a slightly rounded ridge for precise flute placement
• Two angled concave planes — steeper Side 1 for deep or closely spaced flutes, gentler Side 2 for subtle general fluting
• Compatible with round crosspein hammers for a planished surface finish
• Designed for use after forming on the Fretz M-104 Concave Stake
• Part of the Fretz two-stake concave fluting system (M-133A and M-133B)

Specifications

Compatibility

• Use with Fretz Stake Holder H-1 (112.600) for standard bench or tabletop mounting
• Use with Fretz Extended Reach Stake Holder H-1L (112.719) for greater working clearance
• Use with Fretz Double Ended Stake Holder T-101 (112.721) for deeper access — note: requires a larger tang stake holder
• Use with Fretz Extender Holder E-101 (112.726) for additional reach — note: requires a larger tang stake holder
• Recommended companion hammers: Fretz HMR-8 Rounded Narrow Crosspein and Fretz HMR-9 Rounded Wide Crosspein
• Designed for use following the Fretz M-104 Large Concave Stake (112.734)
• Used in sequence with the Fretz M-133B for a complete concave fluting process

Notes

• The T-101 and E-101 stake holders have larger tangs and require compatible larger stake holders — verify sizing before ordering.
• This stake is intended as the starting step in the concave fluting process; follow with the M-133B for finishing.
