Simulate plate quench of1/8in  01 tool steel.  Note that simulation shows only half of the quench (one plate and .063 steel stock) to  better see  center line temperature (e.g. when the knife edge would be after grinding bevel).   This simulation assumes no bevels are ground in the blade before quenching.   Conclusion:  Simulation suggests that in ideal conditions 1/8in steel can be quenched from 800 C to 400 C  in 4 seconds (at the edges, not in the center) using 1.5in aluminum quench plates.    This is fast enough for full edge hardness of most oil hardening tool steels (O1, etc).   Probably fast enough to avoid pearlite in the cutting edge in faster steels like 52100  and 8760.     Definitely NOT fast enough for water hardening steels (W1, 1095 )

Simulate plate quench of1/8in  01 tool steel using 1 inch copper plate.  Note that simulation shows only half of the quench (one plate and .063 steel stock) to  better see  center line temperature (e.g. when the knife edge would be after grinding bevel).   This simulation assumes no bevels are ground in the blade before quenching.   Conclusion:  Copper is crazy good for quench plates. Simulation suggests that in ideal conditions 3/16in steel can be easily quenched from 800 C to 400 C  in 2 seconds (at the edges, not in the center) using 1in copper quench plates.    This is easily fast enough for full edge hardness of most oil hardening tool steels (O1, etc) and fast enough to avoid pearlite in the cutting edge in faster steels like 52100  and 8760 .    Might not be  fast enough for water hardening steels (W1, 1095 )

Simulate plate quench of 3/16in  01 tool steel.  Note that simulation shows only half of the quench (one plate and .097 steel stock) to  better see  center line temperature (e.g. when the knife edge would be after grinding bevel).   This simulation assumes no bevels are ground in the blade before quenching.   Conclusion:  Simulation suggests that in ideal conditions 3/16in steel   can be quenched from 800 C to 400 C  in 7 seconds (at the edges, not in the center) using 1.5in aluminum quench plates.    This is fast enough for full edge hardness of  most oil hardening tool steels (O1, 97 etc).   NOT fast enough to avoid pearlite in the cutting edge in faster steels like 52100  and 8760.      Definitely NOT fast enough for water hardening steels (W1, 1095 )
