Utility Knife 135 mm Dellinger Diamond – 49 Layers ZDP-189 DLC

Utility knife with a 135 mm blade offers a practical combination of the manoeuvrability of a small knife and the versatility of a larger chef's knife. It is compact enough for precise work while providing the blade length needed for cutting vegetables, fruit, smaller pieces of boneless meat, cheese and cured meats.

At the heart of the 49-layer Damascus blade is ZDP-189 powder steel, valued for its ability to form an exceptionally fine cutting edge and retain its cutting performance for a long time. Vacuum heat treatment followed by deep freezing helps harness the potential of this technically demanding steel.

The knife's distinctive character is emphasised by its dark DLC coating and Japanese Wa handle made from ebony wood. Its octagonal profile provides a secure sense of the knife's orientation in the hand, while the multilayer black-and-gold lacquered finish inspired by traditional Japanese Urushi creates a unique decorative pattern and helps protect the wood surface.

The knife comes in an elegant acacia wood gift box, making it a valuable gift for an experienced chef, a lover of fine cooking or a collector of exceptional knives.

Utility 135 mm – Premium Precision for Everyday Tasks

What Is a Utility Knife?

Utility is a multipurpose kitchen knife whose size falls between a small Paring knife and a full-sized Chef, Gyuto or Santoku knife.

Its greatest advantage is the combination of compact dimensions and versatile use. While a small paring knife is ideal for delicate work in the hand, a Utility knife offers a longer blade that is also well suited to cutting on a board.

The 135 mm blade length makes it convenient to prepare vegetables, fruit, cheese, cured meats, smaller portions of boneless meat and other everyday ingredients.

A Utility knife is a practical helper when preparing breakfasts, snacks, cold dishes and smaller portions. It is also useful whenever a large chef's knife feels unnecessarily long or less manoeuvrable.

What Can You Use the Utility 135 mm For?

Why Choose a 135 mm Blade?

Every kitchen knife length has its advantages. Large chef's knives make working with bulky ingredients easier, while small paring knives excel at detailed tasks.

The Utility 135 mm offers a practical middle ground. Its blade length provides enough working space for everyday cutting on a board while retaining the manoeuvrability needed for smaller ingredients.

If you frequently prepare smaller portions, cold dishes, fruit or vegetables, this knife may become one of your most frequently used kitchen tools.

A Utility knife is also a useful addition to a larger all-purpose knife. While a Gyuto or Santoku handles the main food preparation tasks, a smaller Utility gives you greater control over trimming, portioning and more detailed work.

49-Layer Damascus Blade with a ZDP-189 Core

The blade features a 49-layer Damascus construction, with a cutting core made from ZDP-189 powder steel at its centre.

This central layer forms the actual cutting edge and determines its main cutting properties. The surrounding layers complete the construction and create the characteristic Damascus pattern.

ZDP-189 is an advanced powder steel with a high carbon and chromium content. Its main advantage is the ability to produce a very fine cutting edge with long-lasting performance.

In a compact Utility knife, a high-quality cutting edge is particularly valuable for precisely preparing fruit and vegetables, delicate portioning and trimming smaller ingredients. A properly sharpened blade allows clean cuts without unnecessary pressure.

However, the full potential of this steel can only be achieved through proper heat treatment, precise grinding and careful use.

Vacuum Heat Treatment and Deep Freezing

The blade undergoes vacuum heat treatment. A controlled environment with limited oxygen exposure helps protect the steel surface during the process and allows more precise control over the individual heating and cooling stages.

This is followed by a process known as deep freeze. This additional low-temperature treatment helps stabilise the resulting steel structure after hardening and supports consistent blade properties.

The combination of ZDP-189 powder steel, vacuum heat treatment and deep freezing provides a quality foundation for long-lasting edge retention.

However, the knife's final performance is also influenced by blade geometry, sharpening method and correct cutting technique.

DLC – A Dark, Durable Blade Coating

The blade features a DLC – Diamond-Like Carbon coating. This thin carbon-based surface layer is characterised by high hardness, low friction and increased resistance to normal surface wear.

DLC gives the knife its characteristic dark appearance and accentuates the textured pattern of the Damascus steel. It also creates a striking contrast between the blade and the black-and-gold handle.

The coating helps protect the coated part of the blade but does not replace regular care. Even with a DLC-coated knife, hand washing, thorough drying and safe storage remain important.

Octagonal Japanese Wa Handle

The handle is designed in the traditional Japanese Wa style. This term describes a lightweight fitted handle that contributes to good knife control and allows the chef to sense the blade's movement accurately.

The eight-sided, or octagonal, cross-section creates flat surfaces and clearly defined edges for finger orientation. These help prevent the handle from rotating in the palm during use and allow natural control over the position of the cutting edge.

The symmetrical octagonal profile is suitable for both right-handed and left-handed users. Its shape supports both a traditional handle grip and a chef's pinch grip near the heel of the blade.

On the compact Utility 135 mm, the combination of a shorter blade and an easy-to-control Wa handle contributes to precise, comfortable work when preparing smaller ingredients.

Ebony Wood with Black-and-Gold Lacquered Decoration

The handle is made from dark ebony wood. Part of the handle features a special multilayer Japanese-style lacquered finish in black-and-gold to copper tones, creating an irregular pattern that varies slightly from one piece to another.

The decorative finish blends seamlessly into the deep black of the ebony, visually connecting the handle with the blade's dark DLC coating. The lacquered layer also helps limit direct exposure of the wood surface to moisture and dirt.

The design draws inspiration from Urushi – the traditional Japanese art of lacquering, whose history stretches back thousands of years. This type of surface decoration is known for carefully layered lacquer, deep shades and unique decorative craftsmanship.

The striking black-and-gold tones recall traditional Japanese decorative techniques, such as maki-e, which involve working with gold or other metallic powders and lacquered surfaces.

This knife features a multilayer lacquered finish inspired by Urushi aesthetics. The manufacturer has not confirmed the use of genuine natural Urushi lacquer, so we do not describe it as authentic natural Urushi.

Proper Care for the Blade and Lacquered Handle

A premium kitchen knife with a ZDP-189 core requires careful handling. Proper care helps maintain the long life of the cutting edge, the appearance of the DLC coating and the beauty of the lacquered ebony handle.

• Wash the knife by hand only, using a soft sponge and dishwashing liquid.
• Dry the blade and handle thoroughly immediately after washing.
• Do not put the knife in the dishwasher or leave it in the sink.
• Do not soak the lacquered handle in water for extended periods.
• Do not use steel wool or abrasive products on the blade or handle.
• Use a wooden or high-quality synthetic cutting board.
• Avoid glass, ceramic, stone and metal work surfaces.
• For sharpening, use quality water stones or diamond sharpening stones, or a professional sharpening service.
• When storing the knife, protect the cutting edge from contact with other metal objects.
