Great product! I love Alecs channel, I watch it quite often.
I've been using a modified 3 lbs sledge as my hammer, which works fine. I had always wanted to get (or create) a true blacksmiths hammer and its made a difference! The handle finish is a bit sticky at first which caused some blisters, but hey, gotta build them callouses.
My anvil is a solid cylinder of steel, as you can see in the picture, which really indicates just how well you can use whatever is at hand to create, and thats ok!
