Hand Tools โ FAQ
What's the difference between auto-lock and ratchet-lock?
Auto-lock uses a spring-loaded slider that locks automatically at any positionโfast and intuitive. Ratchet-lock clicks into preset depth positions (usually 8-12), offering more repeatable precision for repetitive cuts.
Can I use any 25mm blade in these knives?
Most 25mm snap-off blades are cross-compatible, but thickness varies slightly. OLFA, HAUTMEC, and WORKPRO blades interchange reliably. DEWALT's single-blade design requires specific replacement blades.
How many cuts can I expect per blade segment?
On cardboard, each 25mm segment delivers 50-75 linear feet of cutting. On tougher materials like drywall or carpet, expect 20-30 feet. The 13 segments per blade give you 650-975 feet total on light materials.
Are metal handles better than fiberglass?
Metal handles resist crushing and bending but transmit more vibration. Fiberglass offers better shock absorption and stays warmer in cold weather. For heavy-duty trade work, metal wins. For comfort, choose fiberglass.
What's the safest way to snap off a dull blade segment?
Use pliers or the knife's built-in snapper (if equipped) while pointing the blade away from your body. Always wear safety glasses, as segments can fly unpredictably. Never snap blades with your fingers.
Can these knives cut through plastic sheeting or Tyvek?
Yes, all 25mm utility knives easily handle plastic sheeting, house wrap, and tarps. Use a shallow blade depth to prevent snagging, and let the sharp blade do the work without excessive pressure.
