It's my first time making a knife and I heat treated it with a MAP torch in a makeshift forge. It was a dull red inside so I thought it was a good temperature to quench. Once I took off the lid, it began to cool off really quickly and within 10-15 secs before I quenched it wasn't glowing at all. Once it reached about 125 F, I stuck it in to temper at 400F for 2 hours. I feel like I might not have gotten it hot enough. Would it be safe to re-heat treat it? Would it be worth the work in the end?
Any info is helpful, thanks
