Knife Blades

Match blade material and edge type to the task: high-carbon steel holds an edge longer for heavy cutting, stainless resists corrosion for wet environments, and disposable or utility blades suit scoring and general-purpose jobs; also consider blade thickness, length, and tip shape for precision vs. durability

Common types include straight utility blades, hooked blades for roofing or carpet, serrated blades for fibrous materials, and specialty profiles for pruning, deburring, or scraping; profile choice depends on cutting angle, material control, and safety needs

Replacement blades and packs in this category typically range from budget options under $20 for basic utility packs to $20–$100 for specialty or premium steel blades, with average product prices around the low tens of dollars

Keep blades dry and clean after use, lightly oil carbon blades to prevent rust, store in original packaging or a blade dispenser to avoid damage and injury, and replace blades once dull rather than trying to force cuts that can cause chipping or breakage

Look for blades with secure locking mechanisms in holders, blunt-tip or hooked options for specific tasks to reduce puncture risk, and dispensers or retractable designs for safe handling and storage

Many high-quality steel blades can be sharpened, but thin utility and snap-off blades are designed to be disposable for consistent edge geometry; sharpening feasibility depends on blade thickness, steel hardness, and intended use

Harder steels typically hold an edge longer but may be more brittle and harder to sharpen, while softer steels are tougher and easier to resharpen but require more frequent maintenance; stainless variants balance corrosion resistance with moderate hardness
