This is how I twist / harden my copper for my pressure flakers.

Flint knapping

Thank you so much! I'm a newbie, that was a huge help to me!

[@Bradmoore1979]

You’re welcome! Thanks for watching!

You can also just hammer it, especially the working tip. Anything that work hardens the copper will be fine. Bending it back and forth also will work. If you need it softened however (perhaps to grind or file it into shape) you heat it to a dull red and quench it in water. This softens copper, and does the reverse to steel.

Very interesting! Thanks!

I'm new to flint knapping and want to make my own tools. This is great vs buying copper nails because I'm a lineman so I already have a shit ton of #4 and #6 copper lying around the house. I have enough already that I could make enough pressure flakers to last me a lifetime without ever buying copper. Mainly commenting because I think you deserve more video interaction. Thanks for the advice!

Thank you! I appreciate it!

and Catenary wire is usually a much harder wire than domestic (especially after swaying in the breeze for a decade).

[@linklesstennessee2078]

Good information

[@macbailes3635]

I use the same procedure. Works great.

[@victoryfirst2878]

Would you be willing to make a video of twisting three and five copper wires together like you are twisting one wire Sir ??? Thanks 😀😀😀😀😀

[@Bradmoore1979]

For what purpose?

[@victoryfirst2878]

I am working on making an antenna that receives TV signals. Thanks Brad.@@Bradmoore1979

[@abadodo8468]

exactly how i do it as well

[@charlesenos1483]

Point of information: smaller hardware stores often sell that by the foot. You should be able to pick up a fathom for less than a fiver.

[@chadklaren9537]

I just cut off what i need and hammer it

[@briantaulbee6452]

Just don't twist it till it breaks
