Hatchet type carving tools seem to be an Eastern European thing, but they are certainly worthy of our attention. The broad double bevelled blade is both fishtailed and skewed, giving a useful long edge and two fairly delicate points with superb access.
Really nice for geometric work and letter carving, the cut can be pushed and rolled to create crisply formed curved / linear interfaces for serifs etc.
Best used with softer easy-carving timbers like walnut or lime.
A word of caution, these blades are razor sharp and very pointy, keep your work orgaised and be aware of what those points are doing at all times.
