water quenching ???

My guess is that he is checking for the proper tempering temperature by the way the water vaporizes when dripped on the blade.
 
I guess he is trying to prevent over heating at the tempering temp. by fluctuating the blade temp. betweet 100 C and tempering heat..

bill....so when he tempers it-would u assume he is gonna temper it back in the coals?....is that possible?.....i thought u would have to use an oven but i also assume he is a rural blacksmith and might do things differently than most here.....thanks for any further info.....ryan

Ryan, I believe that is what he is doing. For hundreds of years the were no electric heat treating oven and black smiths/blade smiths just returned the piece that they had just hardened to the fire for a quick reheat. in america i think the most common way to do this was to harden and then file a portin of the edge so that the colors were visible as the blade was reheated stopping at straw or brown or blue or whatever the smith had determined was need for the correct hardness of the tool in question. If you watch the video again you will nitice that as he reheats the blade the drops of water start at sizzling and the last time it is dropped on it just vaporizes which with some practice would give a rough estmate of temp.
