Before diving into the blade-changing process, it is vital to gather all the necessary tools. For this task, you will need the following items:

1. New junior hacksaw blade: Purchase a suitable blade that matches the size and tooth configuration of your current blade. Junior hacksaw blades are readily available at hardware stores or online.

Step-by-Step Guide to Change Junior Hacksaw Blade

Now that you have all the necessary tools, let’s proceed with changing the blade of your junior hacksaw. Follow these steps systematically:

Step 1: Prepare your workspace

Start by finding a clean and well-lit workspace where you can comfortably perform the blade-changing procedure. It is crucial to have enough room to maneuver your tools during the process.

Step 2: Engage the tensioning screw

Locate the tensioning screw on your junior hacksaw. This screw is typically located at the front or back of the saw’s frame, near the handle. Rotate the tensioning screw counterclockwise to release the tension on the blade.

Step 3: Remove the old blade

Once the tension is released, carefully lift the blade out of the saw’s frame. Some hacksaws have blade clamps that need to be unscrewed before removing the blade. Use caution while handling the old blade, as its teeth may still be sharp.

Step 4: Insert the new blade

Take the new junior hacksaw blade and insert it into the frame, aligning the holes on the blade with the pegs or pins on the frame. Ensure that the teeth of the blade face outward to allow for effective cutting.

Step 5: Secure the blade

After inserting the new blade, tighten the tensioning screw back in the clockwise direction. This will secure the blade in place and restore the necessary tension for proper cutting. Avoid overtightening, as it may put strain on the blade or frame.

Step 6: Test the blade

Once the blade is securely fastened, give it a gentle tug to ensure it is firmly in place. Take a moment to check if the teeth are aligned and facing the right direction. This quick test will prevent any potential accidents while using the saw.


Changing the blade of a junior hacksaw is a simple task that anyone can accomplish with a little patience and attention to detail. By following the steps outlined in this article, you can easily replace the blade, ensuring your junior hacksaw remains a reliable tool for your cutting needs. Remember to prioritize safety, wearing gloves and safety goggles throughout the process, and always double-check the blade’s alignment before use. Now armed with the knowledge of how to change a junior hacksaw blade, you can confidently tackle your next cutting project.
