The dinner cutlery is obvious but the bigger knives could be either butchering knives or large carving knives. Hard to say but they are quite good sized. Some of these blanks are 10-12 inches long. Notice how the shape of the blade is curved upwards. This is a natural shape that would evolve from forging the straight steel bar. As the one side gets thinner the material keeps getting pushed upwards until the whole bar ends up with a curve in it. If you have ever done any forging you will know what I mean. Anyway, they worked with the natural tendency of the steel and made the blades curved.
