My mother prefers to hand chop so that she can control the size of the items. I think it’s hard on your palm but this is probably the fourth for Silas chopper she’s had and it’s the only thing she wants.
There’s a reason why America’s Test Kitchen doesn’t recommend choppers. Because if you have chopping skills, you don’t need this. But if you lack chopping skills, which I do, this tool is very helpful. We’ve tried most of them out there. This older model Zyliss is the best.
