    The local supermarker has peanut oil on sale. I have used it deep frying turkeys and it I know the flash point would be above 400 degrees. Its heavy so it should be a medium to fast quench. Anyone ever try this? Tips? Warnings would be appreciated.

    Hi this is DaQo'tah

    Im not able to answer your questions at all, for Im very new to this sport, but Im very interested in what you might learn.

    I have heard many different stories about what oil is best for what steel. I am very confused about what should be my own oil. I have had it clearly told to me by the most experienced Knife Makers that OIL is IMPORTANT!..the best guys tell me to get some Texico type "A"...and so I have searched and found a guy who "Might" be able to send me some if the UPS can ship it without a leak in the shipping 1-gal can.

    also of note is the fact that so many other great knife makers use oil thats free to them like your oil, and they also swear they get the same results?

    sometimes I get the feeling that its left to one's "Faith"?

    Everyone talks like its a matter of the Faith you have in the oil and heat treatments you are useing.

    of the tests people have used to back-up the use of their own oils, I just dont trust the results yet. Everyone who does test one oil against another does so knowing what oil they are testing at the time,,,this knowlege seems to me to be very able to effect the results that they might get. I think what is needed is a "Blind Test". What I mean by this is, that inorder not to have the "Knowlege" of what oil is being tested, effect the way a person might judge that oil, we need to make sure we are "Blind" to what oil is being tested.

    Another thing that I think makes some test results fall into question, is when I read about a oil that was proved better against 4 or 5 other oils in testing. But when you look at how the tests were run, you see that the test was in error from the start.

    They did test type X oil against 4 other oils, thats true, but they did so like this -
    They tested type "X" oil against type "Z",,,then tested type "X" oil against type "Q"...then tested type "X" oil against type "O" oil, etc...so you see, they always had a greater chance of ending up with type "X" oil as being the better one in the end...

    I don't see why it wouldn't work. People use all types of cooking oils. Olive Oil, Wesson Oil, Canola Oil, various meat fats, and I have heard of Peanut oil being used.
    Just make sure that the temperature of the oil is right, for the materials being quenched.:)
