My first 'anvil' was a 2 foot length of 5" diameter round steel bar that got slung out of our local machine shop; the guys put it up in the mill, tried to take a cut... and then the air was full of tiny pieces of end mill shrapnel. I still have no idea what that stuff is, except that it's hard and tough.
Then I bought a little 55lb farrier's anvil, which was fine for making small knives, but tiring... I mnaged to PX it for a decent 250 lb London pattern, which is plenty big enough for me.
Yvsa, that Chinese made anvil of yours; ISTR from posts on RCM and the blacksmiths' NG that a lot of the imported anvils in the US aren't made the traditional way, cast iron faced with properly heat-treated steel. If it's not, you'll soon tell, by the lack of ring and bounce.
