I have a cooking utensil that's basically a flat piece of steel with a curl on one side (see attached file) - think of it as a wide sled.
It's great for making a nice clean, flat sand border around the table - it's really hard to get it even and smooth. This does the trick nicely.
You use it on the sand by pushing it so the curled edge goes over the sand like a sled, and the wide, flat area presses the sand flat in a nice, wide, even path.
The utensil is normally used when you're chopping up food, you hold the curl and scoop up the chopped bits with the flat side.
I would have never thought of this, excellent idea!
I call mine a bench scraper, and used it for unsticking my gingerbread cutout cookies from my pastry board a couple days ago. I have also used it for collecting and maneuvering things like diced onions or chopped herbs from the cutting board into the recipe.
