We have one of those. It’s called “Sparschäler” over here in Germany. I have no idea how to translate it but maybe “a thing that peels and saves as much of the veggie in the process” or savingspeeler?? Whatever, my point is: those little teeth are something else! I got them stuck in the skin of my fingers/hand so often, I got another one without the teeth. The one without teeth isn’t as effective (especially when I peel carrots) and cuts more off the vegetables I peel. Feels smoother, though!
