The RED DEVIL 3271/0C is a single edge razor blade sold in a 5-count card. These blades are a standard trade-supply item used across multiple skilled trades for scraping, scoring, and cutting tasks on job sites and service calls. Single edge design keeps one side protected for safe handling while the exposed edge delivers a clean, controlled cut. HVAC technicians, plumbers, glaziers, and general contractors reach for single edge razor blades when removing gaskets, stripping adhesive films, scraping caulk from glass and tile, or trimming sealant beads flush to a surface.
Single edge razor blades are used across residential and light commercial service work. Common applications include scraping paint overspray from glass, removing old glazing compound, cutting through weather stripping, and slicing sealant or tape during prep and cleanup. The 5-count card format suits individual technicians carrying a small supply on a service van or tool pouch. No specialty tooling is required beyond a standard single edge razor blade holder or scraper handle, both of which accept this industry-standard blade size.
Designed as a standard single edge razor blade for use with industry-compatible razor blade holders and scraper handles that accept single edge blades.
Razor blades are sharp and should be handled only by the protected spine or with an appropriate blade holder. Always insert and remove blades from holders with the cutting edge pointed away from the hand. Dispose of used blades in a puncture-resistant sharps container or blade disposal slot. Keep blades dry and stored in their original packaging when not in use to prevent corrosion and accidental contact.
