From Broken Drill Bit To Knife: Backyard Forging Basics

May 23, 2015 by James Hobson 21 Comments

One of our tipsters sent in a great video showing how to make knives out of old broken drill bits. It comes from [The Art of Weapons] YouTube channel which is run by a 15 year old from the UK. He’s applying old techniques to modern technology and it’s awesome to see someone young with these skills.

The beauty of this hack is aside from the tools you’ll need, it’s practically free to do. Worn out drill bit or other steel tool? No problem – heat it up and make something new. At the heart of this build is making your own forge. There’s lot of options, from using firebricks, to making a soup can forge like he did. From there, it’s really just a matter of annealing the steel (heating it up to red hot, and letting it cool down slowly in sand), and then heating it up again and forming it with a hammer and anvil.

But he doesn’t stop there: he also shows us his method of making handles for knives out of hardwood — its a pretty cool process and the finished knives are beautiful. The video below is a bit long, but well worth the watch if you’re interested in trying your own hand at forging.

Mini-Forge On A Budget

Feeling a little black-smithy? Ever wanted to hammer some red-hot steel into a new shape? Turns out, it’s well within your reach!

We’ve seen soup can forges, paint can forges, and even full blown coal fired forges — but none quite as simple as this. All you need is a fire brick — and some tools.

The problem is, fire bricks are kind of fragile. In order to drill into it without cracking the brick [Mike] advises us to clamp it in a wooden jig to help support it. Slowly drill a long hole lengthwise in it, slightly oblong to allow for your work piece to go inside. Flip the brick sideways, and add a second perpendicular hole in order to insert your gas torch of choice.

Now before you go heating it up, it is wise to reinforce the brick by wrapping some wire around it to prevent it from falling apart when it inevitably cracks due to temperature changes. A more permanent solution is to encase the entire brick in concrete to make it more durable, which [Mike] plans on doing next time. Continue reading “Mini-Forge On A Budget” →
