    Double sheath help

    Not sure if anyone could help with this. I don't make my own leather sheaths due to tendon issues in my arm and so have a leather worker make them for me who is superb.

    Wood stabilising oven / tempering oven project.

    Pickling salts

    Having just had some stainless heat treated in a salt bath the heat treaters (I think ) did not neutralise the salts and so the blanks were quite rusty and pitted when I received them. I am cleaning them in pickling salts at the moment which seems to be doing the trick with the rust but it...
