Victorinox all purpose kitchen knife
It's been a winner for like 20 years, I think.
This is the one knife you really need.
Cites versatility
Yeah, we can geek out on niche knives as much as anybody, but you want a versatile workhorse like that.
This is very sharp.
Cites edge retention, versatility
This is a great knife, and that's because it's great for all kinds of tasks.
Everything from precise things like mincing herbs to chopping vegetables, to cutting up a whole chicken or fish, even for carving your holiday roasts.
It's very agile and maneuverable. It's great for people of all hand sizes. It's ergonomically very neutral.
