Here's the information from Blackland Razors website about different AC blades.
Blade Notes
Feather Professional The standard Artist Club blade. If you are unsure of where to start, start here. Middle-of-the-road aggressiveness.
Feather ProGuard This is the Feather Pro blade with an added guard, reducing aggressiveness. Milder than the Pro for those with sensitive skin and/or light beards.
Feather Pro Super The most aggressive Artist Club blade on the market. The Pro Super is similar to a Feather Pro, but it has increased blade exposure, meaning the blade sticks out from the head more. This makes the Pro Super the most aggressive and efficient AC blade.
Feather SoftGuard A mild blade with a guard and reduced blade exposure.
Kai Captain Titan Mild As the name suggests, this blade is on the mild side of the spectrum, but not overly so.
Kai Captain Titan ProTouch MG Like the Feather ProGuard, this blade is guarded for a mild and smooth shave.
Kai Captain An uncommon blade similar in performance to the Feather Pro, possibly out of production.
Kai Captain Sharpblade An uncommon blade, possibly out of production.
Kamisori An uncommon blade, possibly out of production.
