Hand Tools — FAQ
What's the difference between retractable and folding utility knives?
Retractable knives slide the blade in/out of a fixed handle, while folding knives close like a pocket knife. Retractables are slimmer for tool belts; folders offer better pocket carry and often one-handed opening.
How often should I change my utility knife blade?
Change blades when you notice tearing instead of clean cuts, or after heavy use on abrasive materials. For typical cardboard work, expect 1-2 weeks of daily use. Always use sharp blades—they're safer.
Can I use any brand of blade in these knives?
Most utility knives accept standard trapezoid blades (approx. 2.4" long). However, some proprietary designs require specific blades. Check your knife's manual, but all knives on our list use universal blades.
What makes SK-2 steel better than standard carbon steel?
SK-2 is a high-carbon tool steel with superior hardness (typically HRC 58-60) and edge retention. It stays sharp 30-40% longer than basic carbon steel and resists chipping on tough materials.
Are titanium-coated blades worth the extra cost?
Titanium coating reduces friction and prevents rust, extending blade life 2-3x in humid or wet conditions. For occasional users, standard blades suffice. For professionals or coastal areas, titanium pays for itself.
How do I safely dispose of used utility knife blades?
Tape the sharp edges with duct tape, then place in a rigid container like a plastic bottle or metal can. Many hardware stores offer blade disposal boxes. Never throw loose blades in household trash.
