This is how to make rivets out of nails. In the photo you can see them being used on a hatchet. These are easy to make and are pretty cheap.
Step 1: What You Need
You need -thick nails -a hammer -a hacksaw -a drill and drill bits as big as the nails -something to use it on
Step 2: Drilling
Drill a hole through whatever you will use it on that is as wide as the nail
Step 3: Measuring
Now you need to put a nail through the hole. Make a mark with a sharpie on the nail that is about 1/8 of an inch from the wood.
Step 4: Cut the Nail
Cut the nail at the mark you made with a hacksaw.
Step 5: Finishing
Put the nail through the hole again. Then hit the end until it mushrooms out and you can't pull the nail out. Make sure the nail doesn't bend. You could smooth it down until it is shiny, but I like the way it looks now
Step 6: Applications
I have used rivets like these in many projects. One of my other instructables used it to hold a hatchet head to the handle and it worked perfectly. I have also used it to make knives.
