Here are the material that you'll need:
- 1 x Hard Plastic Card
- 1 x piece of flat steel
- Hot Glue
Step 1: Draw the Shape of Handle
Firstly, You need to draw the shaoe of handle on the plastic card. I will devide the card into 4 parts as in image above. Please keep your mind the ration of those part. This step will require you 1-2 minutes.
Step 2: Cut Them Apart
Cut all parts seperately.
Step 3: Draw Blade on Metal and Cut It Out
Use a peice of metal to make your blade. Here i use s corrugated iron sheet. Draw the blade on that then cut it out
Step 4: Stick Plastic Parts Together
A after having handle part, use tape to stick them together. I recommend electricity tape due to its durability and softness.
Step 5: Stick Blade to the Card
Now you can use hot glue or iron glue to stick the blade to handle. Pay attention to this step, the blade shosuld be glued to the smallest part.
Step 6: Sharpening
In this last step, I recommend a 1000-grits stone to sharpen and smooth your blade. Then you can use a 6000 grit for honing the blade. In sharpening process, you should add some water and oil to make it smootheir and easier. Thank to that you will have a much sharper knife. And be carreful while sharpening because you can hurt yourself. Now, after fisnishing this step, it is high time to enjoy your work.
