Enhance Your Knifemaking Skills and Turn an Old Wrench into a Weapon

Knifemaking is an antiquated craftsmanship. Be that as it may, like many other skills, the traditional bladesmithing appears to be lost in our world of cutting edge technology.

With some practice, you can add knifemaking to your arsenal of survival skills.

Each blade, regardless of whether it’s hammered from old Damascus steel or present-day carbon steel, is made by the same set of tools (electronic or traditional).

A bladesmith needs to have the required materials before making a knife:

  • an old wrench
  • a grinder
  • blacksmithing forge
  • a hammer
  • sandpaper

Remember, a bladesmith needs to wear protective gear, otherwise, you could end up burning yourself with sparks during grinding or forging.

Use goggles, gloves, and breathing masks to maximize protection during the making of your knife.

Stage 1: Choosing the Knife Side of the Wrench

To start with, pick which part of the tool will be used for the blades cutting edge and handle. Use the grinder to straighten up the end where you want the cutting edge to be.

At that point, grind or slice through the wrench to shape the cutting edge.

Stage 2: Setting Up the Blacksmithing Forge

In the meantime, you can make a straightforward blacksmithing forge at home by reusing an old barbecue or any similar item where you can burn pieces of consuming coal (Tip: an old satellite dish can be used in a pinch).

In order for your forge to generate enough heat, a blowing mechanism needs to be incorporated into making the forge.

Stage 3: Putting the Wrench on the Hot Forge

After grinding your blade into shape, place just the blade side of the wrench onto the burning coals (Tip: Make sure the burning coal is generating a lot of heat). Keep it there until the steel gets hot enough for shaping with the hammer.

It’s important to know when the steel is ready for forging. When you see the blade side glowing a red hot or even better, yellow, it’s time to take it to the anvil (Tip: You do not need an actual anvil, any solid piece of steel, big enough to withstand the pounding your knife is about to receive, is perfectly fine.)

Stage 4: Pounding the Steel

When the steel gets extremely hot, place it on a blacksmith’s iron or any metal surface hard enough for help. Presently, you can control the steel.

Start by slowly pounding the knife with force until you can steady your strikes to be able to hit the blade with both force and speed. This will make the steel move in unpredictable ways at first, so take the first time you try to make the knife as a learning opportunity and pound the metal until you are happy with the way your knife looks.

Stage 5: Making the Blade

When you have acomplished that, you can begin making the edge. A belt grinder or an angle grinder are ideal because they can sharpen the edge very precisely.

The belt grinder also gives the knife a smooth appearance. Experts even use the belt grinders to smooth the blades into a mirror finish.

Stage 6: Heat Treating the Steel

After you’ve sharpened your knife, take it back into the forge. Sit tight until the color of the cutting edge transforms into shining red.

Take the blade out of the forge and soak it in motor oil. This will cool down the blade quickly, Do whatever it takes not to apply weight on the sharp edge and let it cool for 60 minutes on a hard surface.

Stage 7: Sharpening the Blade

When your edge has cooled off, give it a nice edge. Make sure to keep your blade sharp by stocking up on these materials.

Stage 8: Enjoy Your Work

It’s very important to enjoy and use the blade! Not many people make custom blades and can call themselves bladesmiths these days.

If you need some blade sheaths to go with your sharp edge, follow these steps. Before long, you will be able to make folding or hunting knives, and different blade shapes to further develop your skills.

Knifemaking is an extremely incredible first blacksmithing undertaking. Forging steel blades has been very hard until recently, we’re fortunate to have modern tools available to us to make the work easier.

Now that you know the basics, pick up the hammer and keep improving your knifemaking and blacksmithing skills!
