Introduction
Thank you for choosing Sharp Half Blades. These high-quality, Hi-Chromium 1/2 blades are engineered for precision and durability, providing a consistently smooth shaving experience. They are specifically designed for use in standard shavette and barber straight edge razors that accommodate half a double edge razor blade or professional pre-cut shavette blades. Each blade is coated with PTFE for enhanced smoothness and longevity, and individually wrapped for hygiene and safety.
This manual provides essential information on the safe and effective use, installation, and maintenance of your Sharp Half Blades. Please read it thoroughly before use.
Important Safety Information
- Handle with Extreme Care: Razor blades are extremely sharp. Always handle blades by their dull edges to prevent cuts.
- Keep Out of Reach of Children: Store blades in a secure location inaccessible to children and pets.
- Proper Disposal: Dispose of used blades safely in a designated blade bank or a puncture-proof container. Do not dispose of loose blades in regular trash.
- Intended Use: Use these blades only for their intended purpose of shaving.
- Inspect Before Use: Before each use, inspect the blade for any damage or imperfections. Do not use damaged blades.
Setup and Blade Installation
Sharp Half Blades are designed for quick and easy installation into compatible shavette or barber straight edge razors.
- Prepare Your Razor: Ensure your shavette or barber straight edge razor is clean and dry. Open the razor's blade holder mechanism according to its specific design.
- Unwrap a New Blade: Carefully remove one Sharp Half Blade from its individual wax paper wrapping. Handle the blade by its dull edges only.
- Insert the Blade: Align the blade with the razor's blade holder. Most shavette razors have pins or guides to ensure correct alignment. Gently slide the blade into position until it is securely seated.
- Secure the Holder: Close the razor's blade holder mechanism firmly. Ensure the blade is held tightly and does not wobble.
- Verify Installation: Double-check that the blade is properly installed and secure before attempting to shave. The cutting edge should be exposed evenly.

Operating Instructions (Shaving)
Once the Sharp Half Blade is securely installed in your shavette or barber straight edge razor, you can proceed with your shaving routine.
- Prepare Your Skin: For best results, prepare your skin by washing it with warm water and applying a quality shaving cream or soap to create a rich lather. This softens the hair and protects the skin.
- Hold the Razor Correctly: Hold your shavette razor at an appropriate angle (typically around 30 degrees) to your skin. The exact angle may vary based on your razor and personal preference.
- Shave with Light Pressure: Use very light pressure. The sharpness of the Sharp Half Blade should do the work. Shave in the direction of hair growth for the first pass, and subsequent passes can be across or against the grain, depending on your skin sensitivity and desired closeness.
- Rinse and Clean: Periodically rinse the razor head under running water to clear away lather and cut hairs.
- Post-Shave Care: After shaving, rinse your face with cool water and apply an aftershave balm or moisturizer.
Note: Shaving with a shavette or straight edge razor requires practice. Always prioritize safety and use caution.
Maintenance and Disposal
Blade Longevity
Sharp Half Blades are manufactured to precise standards for consistent performance. The lifespan of a blade depends on factors such as hair thickness, shaving frequency, and skin preparation. Replace the blade as soon as you notice any pulling, tugging, or discomfort during shaving, as this indicates the blade is dull.
Blade Disposal
Proper disposal of used razor blades is crucial for safety.
- Use a Blade Bank: It is highly recommended to use a dedicated blade bank or a secure, puncture-proof container (e.g., a thick plastic bottle with a sealed lid) for used blades.
- Do Not Recycle with Regular Waste: Do not place used blades directly into recycling bins or regular household trash, as they can pose a hazard to waste handlers.
- Seal and Dispose: Once your blade bank or container is full, seal it securely and dispose of it according to local waste disposal guidelines for sharp objects.
