Hi new to the site.
I am making some of my first knives out of quality metal. I am trying to HT an elmax fillet knife. I followed the directions from where I got the metal. I think it was in the oven for 20mins at 1950°F in 309 foil. Taken out and plate quench between 2 3/4 aluminum plates with compressed air blowing between till room temp less then 5 mins is my guess. Blade was still able to bend with my fingers. Yes bend not flex. Talked to where I got the metal said it should have worked. Talked to UB they said should have worked. Tried a second time same result. Talked UB again they said I could send it in and they can tell me if I got the right metal. Third time 2 knives in ramp up to 1450 hold for 10 mins up to 1850 hold for 5 mins up to 2050 20 mins on one knife different material elmax 20 more mins at temp quench between 3/4 frozen plates compressed air between again still able to bend the blade with fingers again not flexing bending. Handle hardness is low 60's didn't test the blade. Any idea on what I am doing wrong?
