That sounds like a very good set of tools. The accidental hamon is probably due to the lower harden ability of the W2. The section thickness is the limiting factor. There is enough heat retained above the line to prevent hardening and too little below to prevent it. Playing with the cross section a little you can almost specify where the hamon will occur. Fascinating stuff W2.
