Plastic spatulas are usually a disposable item, surviving in a kitchen until they are melted or unpleasantly stained by tomato sauce. Tomato sauce staining can be fought with various weapons: vinegar OR baking soda and even a good soak with a dash of beach. But it is usually a death knell when the handle and the blade start to part company.
But before this otherwise perfectly good spatula heads to the plastic recycling bin, I want to see if I can salvage it. Since there is no evidence of an adhesive, they are probably assembled with a very tight tolerance. The soft blade just squeezed onto the handle stem.
Since there is a dandy little void in the handle, I decided to try my Gorilla Glue trick. I added a tiny bit of urethane based Gorilla Glue (about the size of a pea) into the hole in the blade and shoved in the handle stem. When it had dried a rice sized bit of overspray had escaped. I simply trimmed it off with a blade. Voila good as new.
