Shoveling sand or dirt is fun. It's also messy, which makes it even more fun. But using a little shovel or spade or trowel is just plain ok. Like the HandTrux Construction Digging Tool. It's super durable and slips over your forearm. Grip the handle and flex your wrist forward and the shovel bends.
This will in essence turn your arm into a version of the big digging machines used by construction workers. Yes, your arm will be turned from boring arm into an excavator of mass enjoyment.
