How to use the precision knife

Before you start

• Cut hazard
• Wear cut-resistant gloves
• Wear safety glasses
• Wear long or cut-resistant sleeves
• Dispose of blades in a closed container

• Work on a firm, flat, well-lit surface with the material held in place.
• Cut with the tip moving away from your body and from the hand holding the material.
• Extend only the blade you need and put it away as soon as you finish.
• Replace the blade when it gets dull, because a dull blade needs more force and slips.
• Don't use the tool as a pry bar or a screwdriver.
• Keep tools and refills out of the reach of children.

1. Step 1: 1

   Loosen the collet

   With the tip pointing down and away from you, turn the knurled front piece counterclockwise until the blade is loose.

2. Step 2: 2

   Take out the used blade

   Pull it out by the back end with pliers, or with your fingers on the flat part, never by the edge.

3. Step 3: 3

   Insert the new blade

   Push it straight in, all the way to the bottom of the collet slot.

4. Step 4: 4

   Tighten the collet

   Turn the knurled piece clockwise until the blade does not move. Tighten firmly, without forcing the thread.

5. Step 5: 5

   Check it

   Carefully touch the blade by its spine and, if it moves, tighten a little more before cutting.

1. Step 1: 1

   Hold it like a pencil

   Hold the handle like a pencil, with your index finger on the knurled grip, and cut with the tip.

2. Step 2: 2

   Cut on a base

   Use a cutting mat or thick cardboard, never your hand or an unprotected table.

3. Step 3: 3

   Several light passes

   Lay a metal ruler down and make several light passes. Don't pry with the tip, because it breaks.

4. Step 4: 4

   Cover the tip when done

   Store the knife with the tip covered, never loose in a bag or a drawer.
