What the AI looks for in Knives, Parts & Accessories
- Blade standard
- Standard trapezoid utility blades fit most fixed and retractable utility knives; snap-off blades come in 9 mm, 18 mm and 25 mm widths Blade width and shape must match the knife body exactly.
- Snap-off blade width
- 9 mm for precision and wallpaper, 18 mm for general use, 25 mm for heavy cutting Each width matches a specific knife body and task.
- Specialty blades
- Hook blades for roofing and carpet, serrated blades for insulation, scoring blades for laminate Each specialty blade fits a standard trapezoid knife but cuts a specific material.
- Steel and coating
- Carbon steel is sharpest; bi-metal and coated blades resist breaking and corrosion This trades edge keenness against toughness.
Brands that matter
- Olfa: Reference brand for snap-off knives and blades.
- Tajima: High-quality Japanese snap-off blades.
- Stanley: Standard utility blades and knives.
- Milwaukee: Utility knives and blades for the trades.
- Lenox: Bi-metal utility blades.
- Slice: Ceramic safety-oriented blades and cutters.
What to avoid
- Mixing snap-off widths, since a 9 mm blade will not hold in an 18 mm body
- Dull blades kept in use, which slip and cause more injuries
- Unbranded blades with inconsistent edges
Questions
Are utility blades universal?
Standard trapezoid blades fit most utility knives, but some knives use proprietary blades. Check the knife's blade type.
