Good product
Color: Brown
I love these knives. They are sharp and haven’t rusted on me yet, had them for a year. Cut my finger twice cause they were sharp and I’m clumsy 😂

Great knife block
Color: Brown
I love this knife block! It is definitely a more modern option than the usual large clunky blocks. Looks very stylish and a nice sleek size. The knives are very sharp and look/feel good to use.

Good buy.
Color: Black
Comes with exactly what I wanted for a knife block not all the extras that I dont need or want and doesn't take up very much room in my counter. They dont feel bulky in your hand

decent deal
Color: Brown
As others have already noted, there are very small defects here and there with the product but nothing that's a big deal. The knives are sharp and solid. Overall, it's a very good deal for some very good knives.
It's an attractive-looking set too.
