The knife is a hook knife, great for carving out scoops and the bowl of a spoon. I read much about the use of these knives, and how to carve the Swedish Slojd method, it takes some getting used too, but the methods are very efficient and accurate.
This hook knife is made by Morakniv, a tradition in Sweden, and the cost of the knives are very affordable.
Here is a link to a series of videos by Morakniv and legend Jogge Sundqvuist on use and maintenance.
