Good quality

5 Stars - Excellent Quality and Performance!
I couldn't be happier with this knife set! Each knife is incredibly sharp right out of the box and cuts through everything with ease—whether it's vegetables, meat, or bread. The handles are comfortable to hold and well-balanced, making food prep a breeze. The design is sleek and looks great in my kitchen. I've used them daily for a few weeks now, and they’re still holding up perfectly. This set offers outstanding quality at a great price. Highly recommended for home cooks and pros alike!

Excellent Knives... Highly Recommended
Color: Black, Color: Black
Great, sturdy knives. They cut amazingly. They have a nice ringing sound when you take them out of block. Block is a nice solid wood. The only negative is that the handles get a residue on them if you wash them in the dishwasher. It does go away, but I strongly recommend handwashing these. I definitely recommend this knife set. Great value for the price.

Quality wooden block and nice set of knives for every day use.
Color: White
Bought these for my daughter and son-in-law for their fifth wedding anniversary. Wanted to get something that looked nice and wouldn’t take a lot of room but had a nice variety. The wooden block looks so nice, not too dark-not too light. The variety of knives are perfect for every day use & handles have a nice grip. My daughter and son-in-law use them everyday and love them!

worth every penny
Color: Black, Color: Black
I was honestly surprised by how good this knife set is for the price. I previously owned a $300 knife set, and I can confidently say the Fikshot knives are just as sharp — maybe even sharper right out of the box. The blades slice through meat, vegetables, and bread effortlessly, and they still hold their edge really well after regular use. The full tang handles also feel sturdy and comfortable in hand, which makes prep work much easier.
I also love how sleek and modern the black knife block looks on my kitchen counter. It feels like a premium set without the premium price tag. The built-in sharpener is a nice bonus too.
My only small complaint is the kitchen scissors placement in the block. The scissors tend to rub against the slot when pulling them out, and it scratches the knife block a bit over time. It’s not a dealbreaker for me, but I do wish that part was designed a little better.
Overall, this is an excellent value knife set that performs far beyond its price point. Great for home cooks, new homeowners, or anyone wanting a high-end feel without spending hundreds of dollars.

Finally a knife set that I love
Color: Black, Color: Black
I’ve been needing a new knife set that also came with steak knives and these are great! Very durable, has a nice weight to it, doesn’t feel cheap, great price and they came very sharp! Bonus points for coming with scissors and whatever that sharpening thingy is. Haven’t used that yet bc I don’t know how but we’ll cross that bridge when we get there.
