So I'm trying to learn more about forging. I'd like to get into tool, decoration, and probably weapon making. Everywhere I've looked has advised a larger anvil 75lbs+ but I can't seem to understand why. I understand the difference in types of anvil except for weight. Does an anvil weighing 150lbs have an advantage over the 100lbs of the same make, if so, what's the difference? Better bounce back or what? Everyone talks about how weight matters for your application but I've yet to read from any book, forum, or site as to why it matters.
