Making a Kitchen Knife: Integral Bolster from Round Bar (Knife Making)

This project turns a round steel bar into a kitchen knife with an integral bolster and a wide blade. This is a good example of the transformative nature of blacksmithing to turn steel into completely different shapes just using a forge, hammer and anvil. I will take you through all the necessary steps and provide detailed narration. The knife making skills shown here are fairly straight forward and this could be a project for a beginner to intermediate blacksmith. There is even an attempt at hamon to control the differential hardening of a shallow hardening steel.
