DETAILED DESCRIPTION
Extreme Glide, Uncompromising Efficiency
The Razor Line is designed for riders seeking a pure, fluid, and continuous flight experience. This high-aspect front wing is built for exceptional glide, unprecedented pumping capability, and remarkable performance in downwind and prone surf.
Power, Flow, and Precision in a Single Profile
Every design detail of the Razor has been optimized to turn each input into speed and directional control. The result is an ultra-efficient front wing that maintains clean, stable water flow even through the most delicate transitions. It provides infinite glide thanks to its high-aspect profile, surprising pumping capability for its size, speed and control over long distances, and a fluid response in carves and glides. This set includes the Blackbird Razor 1077 with the Downwind 375 stabilizer and the UHM Blackbird 75 mast. To experiment with different fuselage lengths or use your Kraken stabilizers, try it with the Blackbird Back Tail fuselages for maximum modularity.
Blackbird Technology: Engineered to Perform
Superior hydrodynamic efficiency and reduced drag: the streamlined shape and monobloc construction slice through water and air, improving flow and reducing turbulence for smoother transitions, touchdowns, and rail-to-rail transfers. Active Lift and trim optimization: the front wing generates additional lift, allowing for earlier take-off and reducing pressure on the rear stabilizer for a flatter, faster, and more balanced ride even at high speed. Extreme structural stiffness: the aerospace-inspired fuselage design increases torsional stiffness by over 20% compared to cylindrical fuselages. Full Carbon MONOBLOC construction: the integrated monobloc connection between the front wing, fuselage, and tail ensures minimal flex and torsion, smoother transitions, instant feedback and control, and a truly connected ride feel.
Who is it for?
The Razor 1077 Integrated kit is for ambitious and technical riders, foilers seeking the longest glide and most effective pumping capability, and downwind, SUP foil, and dock-start enthusiasts. Its 1069 cm² surface area, combined with an Aspect Ratio of 11, makes it the perfect tool for light wind conditions and long sessions. This is also the best all-round option in the Razor range, excelling across five disciplines: wing foil, surf foil, pump foil, SUP foil, and downwind.

SABFOIL RAZOR 1077 BLACKBIRD INTEGRATED: FAQ
Sabfoil presents the KR-1077-375-75/BB as the most versatile option in the Razor range, covering five disciplines: Wing foil, Surf foil, Pump foil, SUP foil, and Downwind. Recommended for Freeride, Downwind, Dock-Start, SUP, and Surf, this kit has the earliest take-off in the range, from just 7 to 9 knots.
All three kits share the same M75/BB mast. The difference is the front wing's surface area and aspect ratio: the 737 (648 cm², AR 8.4) is surf-oriented; the 847 (784 cm², AR 9.2) is for allround glide; and this 1077 kit (1069 cm², AR 11) excels in light wind, pumping, and downwind. A larger, high-aspect wing means earlier take-off and better pumping efficiency. Top speeds are 25-27 knots (737), 22-24 knots (847), and 19-21 knots (1077).
Sabfoil offers the Razor 1077 kit in two configurations: Integrated Backtail (KR-1077-375-75/BB, this kit), where the fuselage is built into the Downwind 375 stab, and Modular Full Carbon (KR1077-FCM-SDW375-75/BB), which has a modular setup. Both are the same price (€1899) and Sabfoil states they deliver identical performance.
The SDW375/BB is a Sabfoil stabilizer with a high 10.4 aspect ratio, a 375 mm wingspan, and a 130 cm² surface area. It is specifically designed for downwind and long-distance pumping, maximizing glide and minimizing drag for sessions where efficiency is key.
Yes, the kit includes everything you need: the WR1077/BB front wing, the Downwind 375 stab integrated into the fuselage, the Piantone Blackbird 75 mast, the Carbon Rail plate with titanium inserts (CP02K/Ti), and the complete hardware set (MHQ02, MH144, MH160, MH164, MH171, MH173). Just add your board.
For the M75/BB mast, Sabfoil recommends the Cover Mast A bag (SKU: MA021), which also fits the M63K, M73K, M73PLK, M75BB, and M76. For the front wing, use the Cover Front Wing D bag (SKU: MA028), which is also compatible with the WR847, WR977, WR1077, WB800, WB1000, WR880, WR980, WRP875, WRP975, WRP1075, and W1110.
