Heidi's first BLACKSMITH series impressed me with its compact, capable design. The second generation, the HEIDI BLACKSMITH#2, takes everything up a notch. I've been testing all four variants—the BFK04A, BFK04B, BFK04C, and BFK04D—and they share a significantly upgraded core. The blade is now a 3.92-inch CPM-S35VN steel, a premium powder metallurgy stainless steel known for exceptional edge retention and toughness. The hollow grind enhances cutting efficiency, and the overall length is 7.87 inches. At around 107-108 grams, it's lightweight but feels substantial. The differences lie in the blade finish and handle material, offering a choice between sleek carbon fiber and rugged canvas micarta.
The Shared Foundation: Premium Steel, Hollow Grind Excellence
Every BLACKSMITH#2 shares Heidi's refined design. The CPM-S35VN blade is a major step up, offering superior edge retention and corrosion resistance. The hollow grind creates a blade that slices effortlessly while maintaining a strong tip. The blade is 3.92 inches long and 0.15 inches thick—perfect for a wide range of tasks. The full tang ensures durability, and the weight is perfectly balanced. This is a knife that feels both precise and powerful. The choice of handle and finish is where you tailor it to your preferences.
BFK04A (Satin S35VN / Carbon Fiber): The Sleek Modernist
The BFK04A features a satin-finished S35VN blade paired with a carbon fiber handle. The satin finish is classic and clean, reflecting light beautifully. The carbon fiber is lightweight, stiff, and has a subtle woven pattern that adds a touch of sophistication. At 108 grams, it's incredibly light for its size. This version is for the modernist who appreciates clean lines and premium materials. It's the one I'd carry in a professional setting or when I want my gear to look as good as it performs.
BFK04B (Black Stonewash S35VN / Carbon Fiber): The Stealth Performer
The BFK04B combines the same carbon fiber handle with a black stonewashed S35VN blade. The stonewash finish is rugged, non-reflective, and excellent at hiding wear and scratches. This version feels more tactical and hard-use ready. The black blade against the black carbon fiber creates a sleek, monochromatic look. If you prefer your gear in dark, low-visibility colors and want a blade that will look good even after years of use, the BFK04B is a superb choice.
BFK04C (Satin S35VN / Green Canvas Micarta): The Rugged Naturalist
The BFK04C introduces a new handle material: green canvas micarta. Micarta is a composite of canvas and resin that's incredibly durable, grippy, and warm to the touch. It develops a beautiful patina with use. The satin S35VN blade contrasts nicely with the textured green handle. At 107 grams, it's a gram lighter than the carbon fiber versions. This is the version for the outdoors enthusiast. It feels organic, rugged, and ready for anything. The green micarta is also highly visible, making it harder to lose in the woods.
BFK04D (Black Stonewash S35VN / Green Canvas Micarta): The Ultimate Field Tool
The BFK04D is the perfect marriage of rugged materials and finishes. It pairs the green canvas micarta handle with the black stonewashed S35VN blade. The dark blade against the green handle is both tactical and natural-looking. The micarta provides exceptional grip in wet conditions, and the stonewashed blade hides all signs of use. This is the knife I'd grab for camping, hiking, or any outdoor adventure where I need a tool that's both beautiful and bombproof. It's the ultimate field companion.
Which BLACKSMITH#2 Suits Your Style?
All four share Heidi's excellent design and the premium CPM-S35VN steel. The BFK04A is a sleek, modern classic. The BFK04B is a stealthy, all-black performer. The BFK04C offers rugged, natural grip with a satin blade. And the BFK04D is the ultimate field tool, combining the best of both worlds. Whichever you choose, you're getting a fixed blade that represents a true step up in materials and design—a knife that will last a lifetime and earn its place in your daily carry rotation.
