Alan,
The stock that I bought was all the flutegon shape, if I want another shape I forge it out. They did have other shapes though, he mentioned round and octagon. And, the shipping is not included, nor is tax. Shipping wasn't bad for me, but I suspect your shipping will be much different than mine, being as you are in the UK. And the steel prices change daily here, so a quick call to check costs is a good idea if you really want to know how they compare. I just like the fact that at least there is one steel in my shop that I don't have to write on, or if the lettering gets rubbed off, burned off etc., wonder what it is. That shape can only be one thing. A-33. Its handy because I have tools made from 4140 too. When I forge the flutegon I usually forge the shape I need and leave a small section, or large, depending on the tool, in that unique shape, so when I grab it there is no doubt what steel it is, and I don't have to fret about dunking it in water to cool it, how it will handle the heat, or if its gonna gall. Its tough stuff.
