What is your preferred tempering temperature for 1084? I don't have the skill to do the torch method as I've seen others. I'm going to go with the kitchen oven technique! So what temp and what time? Thanks.
 
Hi Whit.
Going to redirect this over to the Shop Talk forum.

I have gotten temendous performance by edge quenching in 140F oil and tempering three times at 375F....one hour each.

Abuse tests on my Combat Special model have shown that the edge will not chip out when deliberately hacking into rusty old nails in a 2X4.

Thanks gentlemen, I'll go with that advice. Never been steered wrong on here.
 
Whit- Maybe you know this already, but don't trust the settings on your kitchen oven. Get a thermometer so you know what the actual temp in the oven is.:)
 
all good advice given here Whit. do keep in mind that you can select the exact temp within a range of correct temperatures for a particular application, and blade geometry. Oh no! more complications.... :rolleyes: for example you might go for the lower temp 375 or so for a hunter,skinner where keeness and edge holding are the most important, and toughness is a lesser consideration. For a thin bladed butcher/slicer, then a higher temp 400 + will let you use a butchers steel to touch it up and use that amazingly keen wire edge for cutting steaks, etc. Its all good, just depends on the aplication. A thin blade might need a higher temp to avoid being fragile at the edge, while a thicker blade with a little beefier edge can be harder with outrisking chipping....etc. I generally try for a compromise temperature of 390 degrees.
