That depends on what they're for: the more dedicated carving knives are shorter than the more general use oriented knives. Most of my Scandis tend to be around 95 millimeters of blade, that's 3.7", I think. It's a good length, and very common in Scandis. These are general use, not meant for wood carving alone. The dedicated wood carving Scandis tend to be 80 mm or less of blade, sometimes very short indeed.
Sandvik has good steels - not fantastic, but does the job. :thumbup:
