The brand MAM - Filmam, Lda., with more than 150 years of knife manufacturing tradition in Portugal, combines durability of materials with refined ergonomics of use in this model . Blade made of X39Cr13 stainless steel is distinguished by its increased thickness and weight, which makes it easier to cut through bones and divide large portions without risking damage to the blade. The chopper's solid construction promotes efficient force transfer with minimal user effort. The wide surface of the blade also acts as a practical spatula - ideal for picking up and transferring ingredients. Handle made of resistant polymer plastic is designed for comfort, safety and resistance to intensive use. Its properties make MAM 711 a reliable tool - ideal where functionality and durability count .

X39Cr13 is a martensitic chromium steel with a higher carbon content compared to X30Cr13. Its nominal chemical composition is about 0.39% carbon (C) and 13% chromium (Cr). The increased carbon content significantly increases its hardness (often reaching 55-58 HRC after quenching and tempering) and improves its wear resistance and ability to hold a blade. The addition of chromium provides good corrosion resistance, although it may be slightly lower than in steels with higher chromium content. X39Cr13 is used in the production of high-quality knives, surgical tools with higher requirements for hardness and blade durability, as well as other precision tools.

Blade - designed for tasks requiring power and stability. The classic cleaver type shape , with a wide and heavy blade, works well for portioning meat, cutting through bones and chopping hard ingredients. Thanks to the large working surface, it is possible to conveniently pick up ingredients from the board, which increases the speed of work. Made of high-quality stainless steel, the Blade features corrosion resistance, easy cleaning and high impact strength - essential for professional kitchens. The smooth finish reduces sticking, and the lack of a classic grind emphasizes the utilitarian nature of the knife - optimized for power work. The design is engineered to be reliable, safe and effective even under heavy use.

Handle - made of durable polymer plastic, resistant to moisture, grease, chemicals and heat. Its properties make it an excellent choice for professional kitchen conditions, where hygiene and safety count. The ergonomic profile of the Handle adapts to the hand, providing a stable and secure grip, even with dynamic, forceful movements. The textured surface prevents slipping - even with wet or dirty hands. The closed design eliminates the risk of dirt buildup, making it easy to keep the knife clean. Durable blade seating ensures resistance to stress and extends the life of the entire tool. This is a kitchen cleaver, which meets the highest requirements in terms of functionality, convenience and resistance.
