Im just looking for tips on how to go about this best a I want to know what u guys think and any tips u may have.

    If using a file, rub the file with chalk before using. It prevents brass/bronze/aluminum from filling the bottom of the file cuts.

    That looks like an extruded bar. Do you know what alloy it is?
    Bars come in several, from plain brass that's soft and easy to
    work with, to aluminum bronze--which is a tough alloy that
    can be a pain to work with.

    Alloy 936 machinable bearing bronze.
    Im wanting to make this more just to do it more than likely it will probably just be something to put in the safe, if I can make it.

    How tough is bronze? I'm curious because I know its a pretty metal IMO.

    Its not tough like steel, it feels like cutting aluminum to me but it's surprisingly heavy. I just like the color of it and think a dagger would look cool made out of it.

    I figured it wasn't as tough as steel, but ancient civilizations used it for quite a while, so there has to be something to it.

    I'd like one myself. I might do a little research into sand casting one myself.

    936. 80% copper , 7% tin, 13% lead, more or less.

    The copper alloys are kind of fun to work with. Heat them
    to a dull red and quench or let cool---they get SOFT.
    Beat on them cold, they get hard (and more brittle).

    You can do the heat annealing process multiple times. Don't
    get it too hot----we used to heat it with a torch in a darkened
    room until it just glowed dull red. You can hammer it to a
    hard tough surface that will take a fair edge, although the lead
    content in your 936 may work against you.
