One of the “Russian bulat” knives wrought by ancient method of Russian carbon steel: As in old times, every knife is forged by hands from an ingot of good steel. The ingot is forged into blade then all edges are perfected by hammering. And so the blade become tough and compacted at cutting edge. Then the blade is hardened carefully and polished manually. No grinding at high-speed stone give due result: cutting properties of these blades are better than those of most of modern knives.
