[[File:1970s Swiss pencil sharpener Gedess.jpg|thumb|A Swiss-made pencil sharpener from the 1970s]] A '''pencil sharpener blade''' is the cutting component within a pencil sharpener responsible for shaping the point of a [[pencil]]. Like any cutting tool, these blades become dull with use, requiring replacement to maintain optimal sharpening performance. The process of changing a pencil sharpener blade varies depending on the type of sharpener, but generally involves accessing the blade chamber, removing the worn blade, and inserting a new one. ==Types of Sharpeners and Blade Replacement== * '''Manual (Handheld) Sharpeners:''' Many handheld sharpeners are designed as single, replaceable units. When the blade dulls, the entire sharpener is discarded and replaced. However, some higher-quality manual sharpeners feature replaceable blades, often secured by a small screw or clip. * '''Electric Sharpeners:''' Electric sharpeners also utilize replaceable blades. Replacement typically involves unplugging the device, accessing the blade chamber (often by removing a cover or screws), and then swapping the blades. Consulting the manufacturer's instructions is crucial due to model-specific variations. * '''Crank Sharpeners:''' Crank sharpeners (rotary sharpeners) often have more complex mechanisms. Blade replacement usually involves identifying and removing screws or clips securing the blade assembly. Again, manufacturer's instructions are highly recommended. ==General Steps for Replacing a Pencil Sharpener Blade== 1. '''Consult Instructions:''' Always refer to the packaging or manual for specific instructions for your sharpener model. This is especially important for electric and crank sharpeners. 2. '''Gather Tools:''' Typically, a small screwdriver (often Phillips head), tweezers (for handling small blades), and the replacement blade are needed. 3. '''Disassemble:''' Carefully disassemble the sharpener to access the blade. Keep track of all parts for proper reassembly. 4. '''Remove Old Blade:
