I didnt want to go through the trouble of heat treating the knife but you can if you want to.
Remember that I didnt make this knife to be pretty, its just a little beater knife that is fun to make.
Step 1: What you need
1. A sawblade or any useble piece of metal
2. pvc tube
3. little screws and bolts
1. a drill (not needed if you have a dremel)
2. an angle grinder
3. a pair of pliers
4. a file
5. sand paper
6. a work bench with a vise
7. dremel (optional)
8. an oven or heat gun
10. some foam material
11. 2 wooden blocks
12. water proof pen or sharpie
13. nail polish remover and toilet paper
16. hacksaw (you can use dremel instead)
Step 2: Designing the blade
I used a waterproof pen to draw my design and the nailpolish remover to remove any mistakes.
You can also use features that are already there like the hole in the middle of the saw and the teeth.
Step 3: Cutting out the blade
remember to always use your safety glasses when cutting metal!!
Start by securing the metal in the vise or workbench and start scoring the metal.
Do not cut the metal cause you run the risk that the grinder will get stuck in the metal.
You should try to score straight lines to make the next part easier
After scoring the metal about half-way put the metal straight into the vise and bent it back and forewards till it snaps. If it doesnt bend easily try scoring it further.
