   Yes my other option is stainless tool wrapping foil which I use for some   
   items when tempering/normalising and include some wood inside to   
   scavenge the oxygen remaining which results in just minor discolouration   
   like from tempering, no scale. The Condursal was for use with items to   
   be hardened so I could drop them straight into the quench tank without   
   having to remove the foil.

   I have some of that foil too and use it sparingly on longer items. Short   
   tools go in a soup/vegetable can with the lid not completely removed, so the   
   tool can be extracted with tongs or shaken out above the quench, which if   
   oil is in the door opening of the wood stove.   
      
   A can on its side with a floor of charcoal contains a propane torch flame   
   well enough to evenly heat a tool larger than it could in free air. The   
   burning charcoal contributes a lot of distributed infrared. The flame needs   
   to swirl inside the can and have a place to exit, straight in doesn't work   
   so well.
