This Fretz® miniature concave fluting “finish” stake is one of two progressively designed styles available; used in tandem, they streamline the process of adding flutes to concave metal forms. These stakes help you create, then more finely articulate, the pattern of fluting you want—and do it more cleanly and quickly than is possible using wax or pitch. Once you have established the basic fluted form using the "start" stake (available separately), use the deeper curves and more angled peaks on this "finish" stake to sharpen and clarify the flutes you've created. We suggest a cross-peen hammer but with a lighter touch than was need to form the initial lines of the fluting. For straight flutes, choose a straight cross-peen; for curving flutes, choose a curved cross-peen.
