A very simple product, however high levels of accuracy when heat treating are possible when used in a solid fuel forge and paired with a thermocouple and reader. The box section is closed at one end so blades are protected from the flame, reducing scaling. The box is constructed from fairly heavy section steel – it will scale heavily in use and eventually burn through ( better this, than your blades!) but should last a long time.  Be careful though – it is possible to burn the bottom out if you are trying to rush the intial heat- it is important to build up a large mound of charcoal, or coke and allow the fire to burn all around the box, in the case of charcoal it can help to use larger size pieces than you would for forging to allow the fire to spread easily.
