Question: does these knives have grooves or just plain ones ?
Document: I have used Chicago knives for many years (since they were given to me as a gift over 20 years ago). It is nice to see they still have the quality as the first ones had. I have replaced a few since the gift I received and have always gotten Chicago knives. The knife holder was also just perfect, small, but very nicely made.
The knives are what you might expect for the price. They looked like some other Chicago Cutlery knives that I have that are much better so I expected more. They cut more like a saw than a knife and being serrated are not easily sharpened. They also have thinner handles than my original ones. I wish I had shopped a little more carefully and found the better quality ones.
I was looking for a few decent paring knives to replace some older ones that I'd had since I first moved out. I worked my way through college as a cook and chef, but continuing as a chef wasn't an option, financially, in my area. The degree gave me much better options, but I love to cook, and I do most of the cooking in our house. My wife bought me a nice set of Henckels knives over a decade ago. Fast-forward to today, and they are still in excellent condition, but several of my old, cheap paring knives were getting worn out...These popped up on sale as a daily or lightning deal.
Solid, sturdy, and very sharp knives. Good quality.
Chicago Cutlery has excellent products, and these knives fit that pattern!
These knives are my favorite all purpose knives and are used daily for all my slicing and chopping when cooking.
Like most of Chicago Cutlery's knives, they are well-made and durable for inexpensive knives)!
These are excellent steak knives for the money. I have a block set and wanted these to fill out collection.
These knives are a little shorter than you'd expect, but still pretty good, considering the price. The quality is satisfactory.
I love these knives and they come with a nice sleeve to keep them sharp in your drawer. I own several.
Answer: The knives are plain (straight) blades. They are not grooved (serrated). The blades are shorter than you would expect however. After buying this set, I would suggest getting one of the more expensive Chicago sets.
