    Rough Rider The Pipe Doctor Tobacco Bone Folding Pocket ...
    A high-speed doctor knife is a precision industrial blade, typically used in flexographic & gravure printing, made from materials like carbon steel or ceramics, designed to scrape excess ink/coating off cylinders at very fast machine speeds (e.g., 180-220m/min) while maintaining sharpness, durability, and preventing wear, crucial for consistent print quality and reduced downtime. 
    Key Characteristics & Types: 
    • Material: High-speed steel, carbon steel, ceramics (for extreme hardness/wear resistance).
    • Hardness: Very high, often 580-950Hv, to stay sharp.
    • Performance: Reduces friction, heat, and ensures smooth ink application.
    • Shapes: Available in various profiles (e.g., R-ST, Flexotip) to suit different presses.
    • Brands: Fuji Shoko (Doctor Hi-Blade), Daetwyler, Tresu are notable manufacturers. 
    Applications: 
    • Printing: Gravure, flexo, and coating machines.
    • Paper Industry: Scraping rolls in paper mills. 
    Why "Doctor Knife"? 
    • It's a specialized tool that "cleans" or "doctors" the printing cylinder, ensuring only the right amount of ink/coating remains in the cells for a perfect print, similar to how old doctor's knives mixed powders. 
    In essence, it's a high-tech blade for high-speed industrial printing, focusing on precision, longevity, and efficiency.
