I also like that they didn't try to add a knife. If someone's gonna carry their own eating utensil they probably already carry a knife they're happy with. Anyway, I couldn't find one online, nor instructions on how to make one, so I gave it a shot and made a quick version out of wood.
(*I say "fork-spoon" cause this isn't a "spork," which is a spoon with very small tines cut into it. I don't find that sporks work well as a fork or spoon.)
Step 1: The Tools I Used
Besides switching out individual tools, other ways to make this could include carving it using knives, or cutting the handles off a regular fork and spoon and welding the tops together.
Step 2: Trace and Cut
Try to position your outline so the wood grain isn't totally perpendicular to the direction of the fork tines. The more the tines are parallel with the "long grain" the more strength they will have and the less likely they will be to get chipped off ends later on. As you can see, the grain is going diagonally on the fork side. I decided to go with it since it wasn't totally perpendicular, and I was taking a mostly casual approach. Also there really isn't any long grain here since the long grain runs the height of the wood. I just made sure not to make the tines too long or thin in the later steps.
Next I measured down the height of the spoon and fork and decided what angle I wanted them to be at. I clamped the wood to the table, traced that line around the side of the wood, and cut it with a regular large hand saw (the one in the previous photo that has yellow plasti-dip all over the end.) The clamp in this step is probably the only tool I wouldn't know how to improvise.
Step 3: Cut and Shape
Next I took the sanding attachment for my flex shaft tool* and shaped the edges, depth of spoon, and angle of tines. As I did this I would check the thickness and shape by doing the mouth test. I found a good balance of comfortable size and shape, while also making sure it would be durable.
(*Flexible shaft tool is a handheld rotary tool with a hanging motor that is separate from the handpiece. A foot pedal controls the speed. I use it for everything and recommend it highly if you enjoy making things at home and are short on space. A Dremel or similar tool can be a great multi-multi use starting tool, too.)
If you don't have a flex shaft or Dremel tool, a power drill, carving knives, or even handheld files could be improvised for this step. If you are limited by your tools don't worry! Though we've come to expect spoons to hold mouthfulls of liquid they really don't have to. A flatter one like in the original design will be good for most foods, and the broth can be sipped.
Step 4: Tine Time
Step 5: Sand It and Carve a Heart
At this point I decided that this marvelous creation would be a Valentine's gift for someone very loved, so I carved a heart in the bottom.
Step 6: Add the Finish and Be Done
Just smear the oil on and let it sit. I read that it's good to sit it in the sun. It was night so I used a lamp and it came out nicely. It has a lovely smell and I was amazed to see how much the color was transformed from a cold peach color to a glowing orange!
