Our aluminum InterFrame build SF folders share a unique design offering a combination of Carson M16 Series features requested by military procurement specialists. The dual grind Tanto blades were specified because they offer maximum strength. The open build allows two Carson Flippers to be incorporated, resulting in a true hilt— very rare in folding knives. The M16®-13SF Slim Profile Aluminum features a 3.50" (89 mm) dual grind Tanto blade and is ideal when weight and bulk must be kept to a minimum. Blade, frame and hardware are non-reflective tactical black. The blade receives a black titanium nitride coating for maximum corrosion resistance. Kit's trademark dual checkered thumb studs are standard. One-hand opening and closing is quick and smooth. It also features our exclusive patented (1) AutoLAWKS™ automatic safety, which turns the folder into a virtual fixed blade automatically. Our aluminum frame SF features contoured scales of textured, hard anodized 6061 T6 aluminum, with a perimeter radius for a comfortable grip with or without gloves, stainless steel liners with friction grooves, and premium AUS 8 stainless steel blades. Combined Razor-Sharp and Triple-Point™ Serrated edges are standard.
