The Bestech Slyther is the kind of knife that hits the sweet spot: big enough for serious work, compact enough for comfortable carry. I’ve been carrying all seven variants—the BG51A-1, BG51A-2, BG51B-1, BG51B-2, BG51B-3, BG51C, and BG51D—and they share an excellent platform. The 3.66-inch 14C28N steel blade, smooth ceramic ball bearing pivot, and reliable liner lock are consistent across all. At 131 grams and a closed length of 4.80 inches, it’s a substantial yet portable EDC. The differences lie in handle color and blade finish, giving you seven distinct options.
The Shared Foundation: A Versatile Mid-Size Performer
Every Slyther shares the same thoughtful design. The 3.66-inch 14C28N steel blade is a modern stainless with excellent edge retention, toughness, and corrosion resistance. The 3.8mm blade thickness gives it confidence for heavier cuts. The ceramic ball bearing pivot ensures smooth, snappy deployment, and the liner lock is secure and easy to disengage. The G10 handle is ergonomically shaped for a comfortable grip, and the steel clip is reversible. The overall length is 8.46 inches—a perfect size for most hands. The handle color and blade finish are where you make it your own.
The Black Handles (BG51A-1 & A-2): The Classic Stealth
The black-handled versions are the most understated of the group. The BG51A-1 features a black G10 handle with a stonewash + satin blade—classic, forgiving, and professional. The BG51A-2 pairs the same black handle with a sleek grey PVD blade, adding a modern, low-glare finish. Both are versatile, professional, and ready for any environment. If you want a knife that doesn’t draw attention, the black Slyther is a perfect choice.
The Transparent Handles (BG51B-1, B-2, B-3): The Modern Showcase
The transparent-handled versions are a visual treat, letting you see the internal construction. The BG51B-1 features a transparent G10 handle with a stonewash + satin blade—a clean, classic look that shows off the mechanics. The BG51B-2 pairs the transparent handle with a grey PVD + satin blade, adding a touch of contrast. The BG51B-3 uses the same transparent handle with a full grey PVD blade for a sleek, monochromatic look. These versions are modern, unique, and sure to spark conversations.
The Colorful Handles (BG51C & D): Red and Green Accents
The remaining two variants add a pop of color. The BG51C features a striking black and red G10 handle with a grey PVD blade—bold, energetic, and impossible to ignore. The BG51D offers a fresh black and green G10 handle with the same grey PVD blade, adding a natural, outdoorsy vibe. Both are perfect for those who want their EDC to reflect their personality and stand out from the crowd.
Which Slyther Suits Your Style?
All seven share the same excellent design and the reliable 14C28N steel. The black handles are classic and stealthy. The transparent handles are modern and unique. The black and red or black and green versions add bold color accents. Whichever you choose, you’re getting a well-built, versatile EDC folder that’s ready for whatever the day brings.
