I have recently been interested in learning more about Yakut-style knives. I was wondering if the forum could point me in the direction of some historical and general construction information about them, or offer up any knowledge you might have about them. They don't seem to be very popular compared to Puukkos, which if i'm not mistaken, seem to be intended for similar uses (at least in era they were created) except that the Yakut looks more suited for finer cutting and slicing that the Puukko. From what I gather they are forged stick-tang blades with a chisel grind, 4-5 inches in blade length. they seem to have a convex grind on one side, and a flat on the other with a hollowed out fuller-like depression (what is this for?). They are made to process fish, and perform general cutting tasks which were mostly on wood or leather. Are there any specific construction methods, uses, or other major differences between Yakutians and Puukkos? Which design might suit the modern outdoorsman better for tasks like general bushcrafting, carving, simple cutting tasks around camp, and possibly processing game? Finally, what are the reasons for the differences between Puukkos and Yakuts, why do puukkos have relatively obtuse zero grinds, and yakuts have convexed chisel grinds for example? Thanks everyone!
