French steel T5MoV
T5MoV steel – a practical choice for professional butcher knives
T5MoV is a French martensitic stainless steel developed for the production of cutlery, kitchen knives and utility knives. It offers a balanced combination of corrosion resistance, toughness, easy sharpening and reliable cutting performance.
In the Dellinger range, you will find it primarily in professional Pirge PRO 2002 Butcher knives designed for portioning, boning, trimming and meat processing.
What is T5MoV steel?
T5MoV belongs to the group of martensitic corrosion-resistant knife steels. It was developed for the French knife industry and its characteristics meet the requirements for a working blade that must be sufficiently sharp, durable and easy to maintain.
The designation refers to steel containing approximately 0.5% carbon, 14% chromium and smaller amounts of molybdenum and vanadium. These elements together influence hardness, corrosion resistance, edge strength and the steel's response to sharpening.
In Pirge PRO 2002 butcher knives, the edge reaches a hardness of approximately 56 HRC. This is not an extremely hard steel intended for very thin Japanese grinds. It is designed primarily as a durable working steel for regular and long-term use.

Good corrosion resistance
Chromium helps protect the blade during everyday contact with meat, moisture and food juices.
Easy edge restoration
The edge can be maintained regularly with a honing steel and, when necessary, can be resharpened relatively easily.
Working toughness
Reasonable hardness reduces edge brittleness and suits dynamic work during portioning and boning.
Professional use
Suitable for butcher shops, gastronomy, meat processing and regular home use.
Approximate composition of T5MoV steel
| Element | Approximate content | Importance for the blade |
|---|---|---|
| Carbon – C | Approximately 0.50% | Allows the steel to be hardened and influences hardness and edge retention. |
| Chromium – Cr | Approximately 14.0% | Increases corrosion resistance and contributes to carbide formation. |
| Molybdenum – Mo | Approximately 0.35% | Supports strength, edge stability and corrosion resistance. |
| Vanadium – V | Approximately 0.15% | Helps refine the steel structure and supports edge durability. |
The values shown are approximate. The exact composition may vary within manufacturing tolerances. The final properties of the knife are also influenced by heat treatment, blade geometry and grind quality.
Why is a hardness of 56 HRC advantageous for a butcher knife?
For a butcher knife, the highest possible hardness is not always an advantage. The blade must withstand contact with joints, tendons and uneven pressure during work. A hardness of around 56 HRC offers a practical compromise between edge retention, toughness and the ability to maintain the edge quickly with a honing steel.
T5MoV compared with other knife steels
| Steel | Typical use | Edge retention | Maintenance |
|---|---|---|---|
| T5MoV | Professional butcher and utility knives | Medium | Easy sharpening and regular honing |
| 420J2 | Affordable kitchen and specialised knives | Basic to medium | Very easy |
| 1.4116 | European kitchen and professional knives | Medium | Easy |
| AUS-10 | Higher-performance Japanese kitchen knives | Higher | Requires more careful handling |
| VG-10 / 10Cr15CoMoV | Harder all-purpose and Damascus knives | Higher | More demanding sharpening than T5MoV |
The comparison is indicative only. The behaviour of a particular knife is determined not only by the name of the steel, but also by its heat treatment, hardness, blade thickness, grind and method of use.
Why is T5MoV suitable for butcher knives?
A butcher knife is used differently from a thin Japanese kitchen knife. During boning, trimming and portioning, the blade is exposed to changes in direction, lateral loads and occasional contact with harder parts of the ingredient. It therefore needs not only sharpness, but also flexibility, toughness and easy ongoing maintenance.
T5MoV makes it possible to create a working edge that can be quickly realigned with a suitable honing steel during a shift. Once honing alone is no longer sufficient, the knife can be resharpened relatively easily. This easy restorability is more important in professional operation than extreme hardness.
Boning
A narrow and easy-to-control blade allows the cut to be guided around bones, joints, tendons and connective tissue.
Portioning meat
Longer portioning knives are suitable for dividing larger pieces of meat and preparing portions.
Trimming
A precise tip helps remove membranes, fat, tendons and other unwanted parts.
Professional operation
An easy-to-clean construction and quick edge maintenance suit regular professional workloads.
Which Pirge PRO 2002 butcher knife should you choose?
| Model | Length | Recommended use |
|---|---|---|
| Pirge PRO 2002 boning knife | 130 mm | Compact and precise boning of smaller pieces of meat. |
| Pirge PRO 2002 boning knife | 140 mm | Universal size for boning and trimming meat. |
| Pirge PRO 2002 boning knife | 145 mm | Precise work around bones, joints, tendons and membranes. |
| Pirge PRO 2002 portioning knife | 140 mm | Smaller pieces of meat, trimming and precise portioning. |
| Pirge PRO 2002 portioning knife | 160 mm | Versatile portioning and processing of medium-sized pieces of meat. |
| Pirge PRO 2002 portioning knife | 175 mm | Longer cuts and portioning of larger pieces of meat. |
| Pirge PRO 2002 portioning knife | 195 mm | Larger pieces of meat and longer, smooth portioning cuts. |
A butcher knife is not a cleaver
Pirge PRO 2002 boning and portioning knives are designed for guiding cuts around bones and processing meat, not for directly chopping bones or frozen foods. For such use, choose a sufficiently robust cleaver explicitly designed for that purpose.
Handle for safe and long-term work
Pirge PRO 2002 knives are equipped with an ergonomic injection-moulded polypropylene handle. This material is easy to maintain, withstands normal professional workloads and enables a strong connection between the handle and blade.
The shape of the handle supports a controlled grip during boning and portioning. Different colour versions can help distinguish tools according to processed ingredients and the hygiene system used in professional operations.
Sharpening and maintenance of T5MoV
To maintain a working edge, a combination of regular honing and occasional sharpening is suitable. A honing steel is not used to create a new grind, but primarily for ongoing alignment and maintenance of the edge.
- Ongoing maintenance: use a suitable fine honing steel before or during work.
- Thorough sharpening: when significantly dull, use a sharpening stone or professional sharpening.
- Hand washing: after use, wash the blade with a soft sponge and dishwashing detergent.
- Immediate drying: do not leave the knife in water or a damp environment for extended periods.
- Suitable cutting board: use wood or quality plastic, not glass, stone or ceramic.
- Safe storage: protect the edge with a sheath, block or magnetic holder.

T5MoV is a French martensitic stainless steel developed for cutlery, kitchen knives, butcher knives and other utility knives.
2. What does the T5MoV designation mean?
The designation is related to approximately 0.5% carbon content and the presence of molybdenum and vanadium, which help modify the properties of the steel.
3. What is the approximate composition of T5MoV?
Approximately 0.50% carbon, 14% chromium, 0.35% molybdenum and 0.15% vanadium are stated. Exact values may vary according to the manufacturing specification.
4. What hardness do Pirge PRO 2002 knives have?
The edge of Pirge PRO 2002 knives made from T5MoV steel reaches approximately 56 HRC.
5. Is T5MoV suitable for professional use?
Yes. Thanks to its combination of toughness, corrosion resistance and easy maintenance, it is suitable for regular butcher and catering work.
6. Does T5MoV retain its edge for a long time?
It offers medium edge retention. Its advantage is that working sharpness can be restored easily with a suitable honing steel and sharpening.
7. Is T5MoV better than VG-10?
The steels are intended for different uses. VG-10 generally offers higher hardness and longer retention of a fine edge, while T5MoV is suitable for tough utility and butcher knives.
8. How do you sharpen a T5MoV knife?
A suitable honing steel can be used for ongoing maintenance. If the knife becomes significantly dull, a sharpening stone or professional sharpening is appropriate.
9. Can I chop bones with a T5MoV knife?
Do not chop bones with an ordinary boning or portioning knife. Use a robust cleaver specifically designed for bones.
10. Can I wash a T5MoV knife in the dishwasher?
We do not recommend washing it in a dishwasher. Wash the knife by hand and dry it immediately to protect the edge, blade surface and handle.
