This dude shows you how to make a rebar knife with no power tools at all. Rebar is usually made from a mild steel, but it depends on the type. When a building is demolished, the rebar is often extracted for recycling and reuse. These long steel bars are used to reinforce concrete. Rebar is one of the most prevalent pieces of steel around. This video of him making a great knife from an old wrench won’t be the last of his we feature in this post. The YouTuber Trollskyy is a legend when it comes to repurposing old junk into knives. They’re fun to create but may not make the best everyday cutting tools. It depends on the type of wrench you use, but the steel can be hit or miss. The wrench is another common household tool you can transform into a knife. This excellent video from Miller Knives (I appreciate the lack of Muzak and relish in the actual sounds of the workshop) shows how to make a razor-sharp knife from a horseshoe. A horseshoe knife likely won’t hold an edge too well, but making them can be great learning experiences. Horseshoes don’t make the best knives, due to their mild steel, but that doesn’t stop tinkerers from making them. Take a look at this knife with a ram’s head made from a railroad spike by Chandler Dickinson. You can do some pretty cool stuff with the handle as well. You can also get some railroad spikes from McMaster-Carr for pretty cheap too. You can often find these lying near old railroad tracks (though be aware that it may be considered stealing to take one), but you can also grab some at a local scrap yard. The railroad spike is another fairly common starting point for knives. There’s a classic video that shows how to make a knife from a shovel and some concrete, but I appreciate how this video from Rusty shows what you can make at home without many tools. Here’s a great tutorial of a file knife made with common tools. Way back in 2011, I wrote about how to make a knife from a file. Files are made from different steels, such as W-1 and W-1, but a Nicholson file is 1095 carbon steel. It’s not exactly making a knife from scratch, but it gives you a place to start. Many knifemakers start by constructing a knife from a file. Will all pieces of scrap metal make great knives? Heck no! But with the right piece of metal, you can create something useful and even beautiful.ĭon’t believe me? Take a look at these knives made from old junk you can find in your garage or the scrap yard. If you put enough work and skill into it, you could turn nearly any piece of scrap metal into a functional knife. Look in your neighbor’s garage or head down to the scrap yard and you’ll see so much refuse and detritus that it’s not even funny.īut what if you could take those pieces of scrap metal and make them into something practical and rewarding? Well, you can.
