I would say that everything depends on using the correct spade. Mine above were made by Elwell and are 60 years old and still going strong.
The spade needs to be sharp, well balanced & the correct length for the user. Quite honestly, I would be whacked if I attempted to double dig with some of the monstrosities on the market today.
You may notice my own spade is worn on the front right side...after many years of use, this wear happens depending on whether you are right or left handed. I'm right handed, had I have been left handed, the wear would have been on the opposite side.
