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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSide 1\u003c\/strong\u003e is steeper and is used when flutes are positioned close together or when a wide, deep flute is desired. \u003cstrong\u003eSide 2\u003c\/strong\u003e 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.\u003c\/p\u003e\u003cp\u003eThis stake is designed to be used after the project has been formed on the concave Fretz M-104 Stake (part no. 112.734).
