Knifemaking is an ancient art, but it seems like it’s lost in our modern world of convenience. Challenge the blacksmith inside you and try transforming an old wrench into a knife with this project!
How To Make a Knife From An Old Wrench With Knifemaking Skills
It’s really a shame that in all the hustle and bustle of modern life, we’ve lost so many of the ancient skills passed on by our ancestors. The truth is, in order to truly be prepared and survive, you need to reconnect with these primitive survival skills. You also need to know how to be resourceful in a survival situation and find unexpected uses for everyday items. Knifemaking as a skill is an invaluable resource when you’re in a survival situation.
One of those skills is the ability to transform one tool into another. Turning a wrench into a knife, for example, is actually easier than you might think.
Tools and Materials:
- an old wrench
- a grinder
- blacksmithing forge
- a hammer
- sand paper
Let’s get to work!
Step 1: Choosing the Knife Side of the Wrench
Start by choosing which end of the wrench you want for the knife blade and the handle. Use a portable grinder to straighten out the end you chose to be the knife. The grinder will also cut through the steel to shape the blade.
Step 2: Set up the Blacksmithing Forge
You can create a simple blacksmithing forge at home. You can use an old grill or any solid platform where you can place a burning coal. Make sure to incorporate a blowing mechanism in your forge to make enough heat for forging steel.
Step 3: Put the Wrench on the Hot Forge
Place the knife side of the wrench on the burning coal until it’s hot enough for the steel to be shaped. You should be able to determine when the steel reaches forging temperature. At this point, the color of the steel should be red hot or yellow.
Step 4: Start Pounding the Steel
Once the steel gets really hot, place it on an anvil or any metal surface hard enough for support. Now, you can manipulate the steel by pounding it with a hammer until you get the desired shape. The metal may move in strange ways when hit by the hammer. Take this as a test of your blacksmithing skills.
Step 5: Sharpen the Blade
You can start sharpening the blade as soon as you have achieved the form you want for your knife. A belt sander for metal is perfect for the job as it also gives the metal an even, smooth stainless appearance.
Step 6: Heat Treat the Steel
After you’re done working on the blade’s sharp edge, put it back on the hot forge and wait for the color of the blade to turn into glowing red. Remove the knife from the forge then douse it in engine oil to conclude the process. Try not to apply pressure on the blade and allow it to cool for an hour.
It’s time to appreciate the beauty of your work!
