There are way too many kitchen tools out there, some of which you never use. But, sometimes you do find some that are great. Got this avocado one in my stocking a couple years back that I love. There are 3 sets of ‘teeth’ to help with cutting — long, a bit wide on the bottom, then small at the top.
You can use the small one to puncture the skin and start cutting the avocado in half. Then you can use the long side to continue the cutting process.
I will then usually slice the avocado crossways (both ways to make cubes) while it’s in the skin. I’ll make this happen with both the small end with the 3 teeth, then go onto the long side (I seriously just have fun with this thing — sometimes I’ll use the wide bottom). I’ll chop with the wide bottom if I don’t want a clean cut.
Then you can use the wide bottom to scoop the avocado/good stuff from the skin to start making guac. Or, to remove it for whatever other purpose you have for the avocado.
The tool then works well to mix the avocado if you’re making guac — as a spoon or masher-like thing.
(yes, the teeth are facing away from what I was cutting, but it was all for photographic effects)
