This is my first real throwing star, and i should be making a few more until the end of august (after which i should start cranking a bunch more out), so keep checking. This one is pretty dangerous, very durable and cheap and easy to make.
Step 1: Materials & tools
You will need:
2 utility knife razor blades
1 roll tin solder (has to be tin)
1 bottle of flux
1 metal stick of some sort (i used a small flathead screwdriver)
The tools you will need are:
Small blowtorch with butane
Metal tray (Has to be hard, no foil pie tins)
Soldering gun (regular soldering irons will work, but they are much harder to use)
A good work surface that cant be destroyed easily
Step 2: Setting up
Put whatever you're going to be working on down on a table with good light and plug in your soldering gun. Put your razor blades in the pattern of the final throwing star, and melt some solder on both edges. This does not need to even hold.You could get a wet paper towel to cool off the project, but wait a bit because it messes up the solder if its still molten.
Step 3: Linking the razor blades
Put both razors back to back as shown, then heat up the razor blades with the torch. While they are still hot, put a drop pr two of flux on the hot solder, then pick up your metal stick, re heat the solder, and smear it around all over the joint. Do the same on the other side.
Step 4: Go back and do it on the other side
You dont absolutely have to do this, but it definitely makes it look more symmetrical, much stronger andeasier to throw.
Step 5: Final prep
This step is also optional, but it makes it look much better, Take a wet sanding sponge (sorry, not listed in materials) and scrub off the heat damage caused by the torch. I almost like the burm look the metal gets, but not the rust stuff on the outer layer.
