Fwiw, there's a difference...
A shovel blade is bowl-shaped(concave), a spade is flat(or nearly & has a straight edge).
A shovel has a longer handle, a spade may have a T or D handle.
A shovel has a larger blade/scoop, a spade smaller.
A shovel is for breaking up, digging, and turning. A spade for slicing & moving loose material.
I have a long-handled shovel, a short-handled shovel with a D-handle and a short-handled spade with a D-handle. They're all useful at different times.
I usually take the short-handled shovel to the beach, although I can imagine there could be a time I might wish for a longer handle. I've never used a shovel yet on the beach in 31 years, but still carry one. Or two, I forgot about the little folding shovel.
