131,15 €Kizer Madrac CL AirTi Black Aluminum, Satin M390 by Matteo Pignatelli – an ultralight EDC folding knife with titanium liners
The Kizer Madrac CL AirTi K3693ACS1 is a lightweight and exceptionally slim EDC folder designed by Matteo Pignatelli. The design combines an M390 steel Sheepsfoot blade, a black aluminum handle, and a satin finish, creating a functional knife focused on comfortable carry and precise everyday cutting.
The AirTi series utilizes skeletonized Ti-6Al-4V liners, which reduce weight without compromising handle rigidity. The Kizer Clutch Lock™, thumb stud, and ball bearings ensure smooth, two-handed operation, while the reversible tip-up clip makes it easy to customize how you carry it.
M390 – Powder steel for Heavy-Duty EDC
The blade is made of M390 steel, which offers high wear resistance, excellent edge retention, and high corrosion resistance. This material is well-suited for a folding knife intended for regular, everyday use.
Sheepsfoot and flat grind
The Sheepsfoot profile provides a well-controlled cutting edge and a stable tip, which facilitates precise utility work. The flat grind reduces resistance during cutting and makes good use of the blade’s slender geometry.
Satin-Finished Blade
The blade surface is finished using the Satin method, giving it a classic, technical look. The satin finish complements the black handle and the minimalist character of the AirTi design.
Aluminum handle and Ti-6Al-4V skeletonized liners
The handle is made of aluminum, and its construction is reinforced by skeletonized Ti-6Al-4V liners. This allows for high rigidity despite the knife’s very thin profile and low overall weight.
Kizer Clutch Lock™ with spring adjustment
The Kizer Clutch Lock™ allows for comfortable operation by both right- and left-handed users. The mechanism utilizes an adjustable internal spring system, which allows the lock’s performance characteristics to be tailored to the user’s preferences.
Thumb Stud and Ball Bearing
The Thumb Stud is used for opening, while ball bearings reduce pivot resistance. This combination ensures smooth, fast, and consistent operation of the mechanism.
Reversible clip and open-frame Handle design
The stainless steel clip can be mounted on the right or left side in a tip-up configuration. The Handle features black stainless steel spacer sleeves that support the folder’s open and lightweight design.
