Rated 3 out of 5 by from Still a fine knife but it has changed. The handle of this knife I just received is lighter than my originals, the plastic differs, it throws the balance off. I have the original set I purchased in the late 1980’s, including one of the two Four Star 5” Serrated Utilities. I’ll be stopping by a cutlery retailer to see if the engineering changed or it is this distributor. It is noticeable without weighing, but I did weigh it to be sure.

Rated 5 out of 5 by from One more time! Well, we finally broke down and replaced this wonderful knife. The knife we are replacing is the exact same model that we purchased in 1991. I am able to sharpen the other 9 or 10 of the Zwilling knives of that same vintage but not this one as the serrations are too small and have been unable to find a professional knife sharpener locally. As to the knife it is wonderful and one of the top 2 favorite knives we own (the other is the 6" chef's knife). It is perfect for slicing bread, tomatoes and other foods that are best cut with a serrated blade. The fact that we bought the same knife twice says it all.

Rated 5 out of 5 by from Very Handy This knife is so versitile, I don't ever want to be without it. Great for slicing foods with hard skins and soft interiors. The serrated edge never needs sharpening and is always reliable! Not to heavy, but heavy enough to feel substantial. Love the grip on the molded handle which makes it easier to use, and allows for longer periods of use. The steel is stain resistant and looks like new everytime I wash it. Can't say enough about this knife!

Rated 5 out of 5 by from Bought a second, used so often. Four Star 5" Serrated is a most utilitarian knife. Feels very comfortable to use - well proportioned handle-to-knife size (I'm 7 women glove size). I use for everything needing serrated edge and other uses including cutting veggies. Wanted second serrated knife so, tried Classic 5" Serrated Knife but returned because handle is way too small to grip and knife is smaller size. Bought a second of the Four Star 5" Serrated.

Rated 5 out of 5 by from Tomato Knife is an outstanding kitchen tool! I bought this knife about twenty years ago, and have loved using it--almost exclusively with tomatoes--all these years. I had a house guest here a little over a month ago who noticed me using the knife and said she wished she had such a good knife. I sent her and her husband one as a gift, and they phoned me to say they used it the day it arrived, and are enjoying it as much as I treasure my own.

Rated 5 out of 5 by from Lost and Found My Knife I had my five inch serrated utility knife (AKA tomato slicer) since my parents gave us a Henkel set back in the 1970s, and was really sad when I took it to a meeting to slice a cake I was sharing and lost it. It is, as others have said, the most useful knife in the set. I was thrilled to be able to find the same knife that matched my old set perfectly! These really are great knives.

Rated 5 out of 5 by from Most used knife in my set I couldn't be without this knife. I use it more than any other in my 6 piece set.

Rated 4 out of 5 by from It was a good run... I got my first one over 10 yrs. ago after finding out how they were made an was truly impressed with the warranty as well as the product. Soon after I got a butcher block and customize my own set along with a large sharpening steel & 2 types of scissors. One of my saddest days was opening a box after moving into my new apartment and finding one of my favorites, my 5" serrated broken..., it was a good run an I was a little sick until I got it replaced.

Is there a way to sharpen this knife?

Asked by: Casper
Serrated knives are very difficult to sharpen. We do not make any sharpeners that are capable or sharpening serrated edges. You can check with professional sharpening services, it is rare, but you may be able to find one willing to sharpen a serrated edge (our service is not able to). Essentially, you need to use the appropriate sized file or rod and sharpen each serration individually by hand.
