ZWILLING TWIN 1731 8-inch Bread Knife is rated 5.0 out of 5 by 16.
Rated 5 out of 5 by from Ultimate Bread Knife How many people can brag that their knives are made from the same steel that was used on space shuttle bearings! Cronidur 30 is 100x more durable than any steel on the market. The solid ebony handle is so beautiful and has the most incredible weight. It feels like an extension of my arm. The curved bolster assures me that I'm holding the knife correctly and helps me slice through everything with ease. The serrated blade is designed to minimize wear and to slice through bread without smashing or tearing. It will also handle large melons with no problem at all. 1731 line was designed as an anniversary edition; only a limited number of trees where cut down. So it truly is a collector's item.

Rated 5 out of 5 by from For a top-of-the-line bread knife, the Twin 1731 series is it!! It doesn't get any better than this from Zwilling! Constructed with the curved bolster, much like the Pro series, this will give you extra comfort and control for your hand and finger in the pinch grip form. Made with the ice-hardened process, it will be super-sharp, stay sharp and remain durable and rust and chip free for the life of the knife! It still has a flexible blade, while remaining sturdy and with a good knife balance. Finished by artisans who care about every detail and make this knife one to keep and pass down.

Rated 5 out of 5 by from Twin 1731 series are among the nicest knives you will ever use. Beautifully forged from Cronidur 30 steel which reaches an impressive 60 on the hardness scale these knives will retain their sharpness use after use and are highly corrosion and chip resistant. The bolster is forged with a unique curve to provide the thumb and forefinger a comfortable pinch grip. The ebony handle is unmatched in beauty and simplicity. The teeth of this serrated edge are designed to first puncture the outer crust allowing the edge to glide smoothly through the softer inside without tearing or crushing.

Rated 5 out of 5 by from Great looking bread knife The Twin 1731 collection is one of the most beautiful and best that Zwilling has ever made. They took the look of the Zwilling Pro bread knife with the curved bolster, but they used a harder steel with the Cronidor 30 (a steel used on space shuttles) that is harder and sharper and then accented the blade with an ebony wood handle that is seamless and rivetless, making this a statement knife. A very unique bread knife, this is the German knife you want in your kitchen for slicing not just bread, but citrus, veggies like tomatoes.

Rated 5 out of 5 by from The last bread knife you will ever buy! These are hands down the best German knives on the market. An heirloom collection that will last your life time and those after you. The Ebony wood handles are slim and feel smooth and secure in the hand and the curved bolster is made to make the pinch grip comfortable and puts less stress on the wrist. With a super sharp serration this bread knife will cut like a Japanese style knife and the Cronidur 30 steel keeps the edge sharp through the toughest projects.

Rated 5 out of 5 by from amazing bread knife This knife is a masterpiece. The Conidur steel blade is extremely sharp. The German forged blade is very durable and holds an edge for a long time. The curved bolster makes it a true extension of my arm giving accurate straight cuts. The handle is attractive and very comfortable to hold. The blade is great for bread, tomatoes, melons and anything else with a thicker exterior and soft inside.
