I've used the 1 brick forge (and extended it end-to-end to a 2 bricker for bowie knife work) - I'll just agree with the others - - - and add that you want to wrap some bailing wire around it - the high temp bricks tend to crack after multiple heating/cooling cycles. I've changed over to using a home-built propane forge with a T-Rex burner (more room, more even heat) but keep the 1 brick forge around for small, quick hot work - - - and if you wanted to take your forge to a hammer in it's a *!#@ of a lot easier to take the 1 brick forge!!!
