Hi All,

Well I have finished making my first razor out of 1084fg steel but it will not take an edge.
I have triple tempered in a precision oven at 230°c (446°f) and the steel is soft enough but I keep getting microchips at the edge when I go to hone it.
When I first hardened it I think the steel was not hot enough. I left it in the oven at 815°c (1499°f) for about 4 minutes.
It was glowing a dull orange and there was no flame up when quenching it in warmed vegetable oil.
I suspect that if the blade is not hardened properly then the austenite did not all get converted to martensite and so the grain will be weird.

My question is, can I just repeat the hardening/tempering process with the blade fully ground?
Do I need to normalise before re-hardening or can I just go ahead and whack it in at 815°c again?

It is a 1/4 hollow grind so I suspect that the edge will warp but at this point I have little choice.

Cheers,

Ash.
