Blade thickness for quenching


Recommended Posts

I'm working on a hunting sword that has a 21 inch blade made out of 1075. The thickness at the hilt is 5/16. Tapering down to about an 1/8 at the point. One inch wide. On my knives I leave the blade about the thickness of a dime to prevent cracking during the quench. Is that a good rule of thumb for these longer blades as well or should it be thicker?
Thanks very much!

I would always allow a little extra thickness on a sword to allow for small corrections in warping to be ground out. However.....You can not leave the edge thicker than the thickness that will fully  thru harden in the steel you are using.......leave as much thickness as you can get away with whilst getting good edge hardness.
