Original Shaver Head Blackstone Electric Shaver Pro Waterproof Dual Layer Blade

The Blackstone shaver is a popular and affordable electric rotary shaver known for its 3D floating heads, wet and dry shaving compatibility (on some models), and convenient USB Type-C charging. It is designed to provide a close and comfortable shave by adapting to facial contours. 
Key Features
3D Independent Floating Cutter Heads: The shaver is equipped with three sets of independently floating cutting heads that flex and adapt to the curves of the face and neck, increasing the shaving area and efficiency.
Wet & Dry Use: Most variations, such as the Blackstone 3, are IPX7 waterproof, allowing for a comfortable dry shave or a refreshing wet shave using foam or gel, and enabling easy cleaning under running water. The original Blackstone model is also washable.
ESM Intelligent Shaving System: The Energy Smart Manager (ESM) system ensures consistent power delivery, even when the battery is low, to prevent the blades from clamping on hair and causing irritation.
Ultra-thin Double-Ring Cutter Net: The dual-loop blade design increases the contact area between the blades and the face, effectively doubling shaving efficiency and capturing even the shortest hairs.
Automatic Grinding Blades: The blades are made of high-quality Japanese steel and are designed to self-sharpen during use, ensuring a consistently sharp edge and long lifespan.
Pop-up Trimmer: A built-in, integrated pop-up trimmer is included for detailing sideburns and shaping beards.
USB Type-C Charging: The shaver features a universal USB-C charging port, making it highly portable and easy to charge with the same cable used for many smartphones or a power bank.
Long Battery Life: A full charge (typically around 60 to 90 minutes) provides approximately 90 minutes of cordless runtime, which can last for several weeks of daily use.
Low Noise Operation: Despite its powerful 5W motor, the shaver operates at a low noise level of around 67dB for a more pleasant grooming experience.
