Knife Making Without Tools

Step 4 Start Wrapping

If your cord is nylon get it wet first.
If it's cotton or other cellulose fiber, make sure it's dry first.
Nylon shrinks when it dries, cotton shrinks when it's wet.

You don't really need the hole, that's just something to make it look less like a butter knife.
If you drilled holes poke the cord through one of the holes.
Leave a tail a few inches long.
If you skipped the hole just lay down the tail and wrap over it.
Wrap over the tail until you get halfway up the handle.
