Mac Professional Flexible Fillet Knife – 175mm (Made in Japan)

The Mac Professional Filleting Knife 175mm is the thinnest and most flexible blade in the Mac Pro collection—engineered for precision work where delicacy and control matter most.

At under 1.0mm thick, this ultra-flexible blade bends to nearly a 90-degree angle, making it ideal for expertly filleting soft, delicate fish like sole, flounder, and trout. The slim, tapered profile also excels at slicing sashimi or removing skin without waste.

Handcrafted in Japan with razor-sharp MV steel and a well-balanced pakkawood handle, this knife is a must-have for seafood lovers and professional chefs alike.

Key Features:

• Blade Length: 175mm
• Blade Thickness: <1.0mm (extremely flexible)
• Blade Material: High-carbon Molybdenum Vanadium (MV) steel
• Hardness: ±60 Rockwell
• Handle: Black Pakkawood with bolster, triple-riveted for stability
• Edge: 15° double bevel (on each side)
• Collection: Mac Pro
• Made in Japan 

Best For:

• Filleting delicate flatfish (e.g. flounder, sole)
• Skinning or deboning fish with minimal waste
• Slicing sashimi or fish for sushi
• Precision cuts where flexibility is key

Why This Knife Stands Out:

• One of the thinnest and most flexible fillet knives available
• Designed for clean, controlled filleting of delicate fish
• Excellent for sashimi slicing without tearing or bruising
• Lightweight and balanced for all-day use

Pro Tip:

Use long, confident strokes to let the blade flex and follow the natural curves of the fish. The extreme flexibility gives you maximum contact with the bones and skin, minimizing waste and improving yield—especially with flat or soft-flesh fish.
