DittoI have something like the pic below for 10 - 20 years, but I go to a knife and large metal spoon every time.
Knife to cut in 1/2 and removed the pit
Large spoon to scoop out each half
Knife to cut avocado in to desired shapes and sizes
Whole process takes about 1 minute ( at the very most)
***Would probably take 5 X that time to find the avocado tool***
Maybe I used the avocado tool 3 times in 20 years.
