Making a knife from a car.

Admire your handiwork.

Starting piece.

Find the leaf spring on your vehicle. (the flat bar near the tires). Cut a chunk out.

Divide into two.

This is 5160 spring steel, a wonderful alloy of carbon and iron, flexible and strong.

Forge down to a point.

Forge some more.

Almost there

Forge out the tang.

It should look like this:

Curve the end.

Fold it in the shape of your hand.

At this point, heat the whole knife to a red heat (use a blow torch or a barbque pit.) , and dip in vegetable oil. It should look grey. Cool it down until cold and then toss it in your oven for an hour at 365 degrees F. Once it's a dark yellow to brown, you have a knife.

Another angle.
