With the replacement blade for the Fiskars finger scissors (art. no. 132664) you can cut out fine motifs easily! The set includes 2 knives for an optimal cutting result. The finger tinkering knife is ideal for filigree work, because you have the feeling in your fingertips - just like when writing - and can therefore work very precisely. To change the blade, turn the collar of the finger craft knife counter-clockwise. The old knife is loosened so that you can replace it. Then close the neck again so that the new blade sits firmly in the slot.
