Gooseneck (0.6mm)
The classic spiral curve of the gooseneck incorporates a tight curve at one end, a medium curve at the other and a large radius on the outside edge, plus a slow transition and a fast one between the three curves. By skewing the scraper to the work, you can tighten any of these radii to match the required shape.
Rather than sharpening the whole thing, you normally just put a hook on the bit you need.
