Who it fits

Key specs explained for this knife

Knife Type: Boning & Fillet Knife

This designation tells you the blade geometry is optimized for separating meat and fish from bone. You get a narrow profile that slips between joints and along ribs with minimal waste. This spec helps you distinguish it from general-purpose chef knives or heavy cleavers. If your main task is deboning poultry or filleting fish, this specific type ensures you have the right tool for precision work rather than chopping.

Blade Length: 6-In

A six-inch blade offers a balance between control and reach. You can maneuver easily around small chicken carcasses or fish frames without the blade feeling cumbersome. This length is manageable for detailed work where you need to see exactly where the steel meets the bone. It is shorter than a standard chef knife, making it easier to handle in tight spaces where a longer blade might get in the way or lack precision.

Blade Material: Stainless steel

Stainless steel provides corrosion resistance, which is vital when handling raw meat and fish juices. You do not need to dry the blade immediately after every wash to prevent rust. This material holds an edge well enough for daily professional use. It is easier to maintain than carbon steel, which requires more care. This spec ensures durability and hygiene in a wet kitchen environment without complex upkeep routines.

Handle Material: Fibrox

Fibrox is a textured, slip-resistant polymer handle designed for wet and greasy conditions. You get a secure grip even when your hands are slick from handling raw meat. The material is also lightweight and easy to clean. This spec is important for safety and comfort during long prep sessions. It differs from wooden or plastic handles that may become slippery or harbor bacteria, offering a practical solution for professional kitchen hygiene.

Design and build specs

The listing specifies a 6-inch stainless steel blade with a curved profile and flexible construction. This geometry allows the blade to bend along the contours of bones, making it suitable for delicate tasks like filleting fish or deboning poultry. The steel type suggests standard corrosion resistance for kitchen use. You get a narrow width of 1.77 inches, which helps the blade slip between joints without wasting meat. The overall length is 11.2 inches, providing adequate reach for controlled cuts.

The handle is made from Fibrox, a material noted for being textured and slip-resistant. According to the listing, this handle is ergonomically designed for balance and comfort during extended use. It is also NSF approved, indicating it meets public health standards for commercial environments. The color is black, a practical choice for visibility against light cutting boards. The total weight is 3.2 ounces, making it a light tool that reduces hand fatigue.

The model number is 5.6613.15-X1. Variations exist in blade style, including straight or semi-flexible options, but this specific unit is curved and flexible. The height of the blade section is 0.2 inches. This thinness aids in precision slicing. The handle design prioritizes grip security over aesthetic flair. You should expect a utilitarian finish focused on durability and hygiene rather than decorative elements. The build supports professional daily use.

Setup and everyday use

You do not need to assemble this knife. It arrives ready for immediate use. The primary setup step is simply washing the blade and handle with warm water and mild soap before your first cut. The listing notes that the handle is NSF approved, which indicates it meets public health standards for commercial food service environments. This certification suggests the Fibrox material is durable and easy to clean in high-volume kitchens.

For daily use, the knife is designed for professionals who work with meat and fish all day. The 6-inch blade length provides control for detailed work. The curved, flexible stainless steel blade allows you to follow the contours of bones closely. This flexibility helps you make thin, precise cuts on delicate proteins like chicken or fish. The 3.2-ounce weight offers a light feel, reducing hand fatigue during repetitive tasks.

The black Fibrox handle features a textured, slip-resistant surface. This design prioritizes safety and comfort when your hands are wet or oily. The ergonomic shape balances the knife for steady handling. You can maintain the sharp edge using Victorinox knife sharpeners, such as parts 7.8715 or 7.8721, which are sold separately. The product is backed by a lifetime warranty against defects in material and workmanship. This coverage applies to the Swiss-crafted construction, ensuring long-term reliability for your kitchen tasks.

Before you buy this knife

This knife is a specialized tool for separating meat and fish from bone. You need a reliable sharpener to maintain the edge. The listing recommends specific Victorinox sharpeners, such as Part#7.8715 or Part#7.8721, which are sold separately. Ensure you have one before buying. The blade is six inches long with a curved, flexible profile. This geometry allows the steel to bend along bone contours. You should check if this flexibility suits your preferred cutting style. Some users prefer stiff blades for heavier tasks. This model is ideal for delicate poultry or fish. It fits well alongside other boning knives in your collection. The Fibrox handle provides a secure grip when wet. You must wash it by hand to preserve the finish. Store it safely to protect the edge. This knife is not a replacement for a chef’s knife. Use it only for its intended purpose. It complements your other tools by handling intricate deboning work efficiently.

Check before you buy

• Verify you own a compatible knife sharpener for maintenance.
• Confirm the flexible blade suits your deboning needs.
• Check if you need a different blade stiffness.
• Ensure you have proper storage for the sharp edge.
