A method of using a knife (1;1'), which knife has a knife handle (4), a knife blade (3) extending in elongation of the knife handle (4), safety means (2) including at least one strap (7) having a strap opening (7'), and the at least one strap (7) is secured to or at a free end (5) of the knife handle (4). The method comprises the steps of providing at least one strap (7) with a strap opening (7') having a size selected to configure the at least one strap in a first position and in a subsequent second position, wherein in the first position the operator inserts a finger (9,12) through the strap opening (7') and the at least one strap (7) engages the inserted finger (9,12) and/or the interstice (14) between two adjacent fingers (9,12), and in the second position the at least one strap (7) is arranged lengthwise the knife handle (4), and when kept stretched has a length that is sufficiently long to allow the operator to position a hand (10) on the knife handle (4) but no longer than the selected size of the at least one strap (7) prevents at least the palm (11) of the hand (10) of the operator to reach the knife blade (3) when the finger (9,12) is inserted, inserting the finger (9,12), grasping around the knife handle (4), and performing a cutting action while the finger (9,12) is kept inserted through the strap opening (7'). The operator can work fast and safe from injuries. The safety knife's knife handle (4) can easily be angularly repositioned and rotated in the hand (10) of the operator if desired, and the knife is particular useful in slaughterhouses where the working pace is high and pressure on the workers often causes cutting injuries. |
