  • Magnetic knife supporter
    Patent number: 7934610
    Abstract: The knife supporter comprises at least two magnetic boards has same magnetic polarity at inner side facing each other, so that the magnetic boards repel each other, and a supporting frame slidably supports the magnetic boards, so that the magnetic board can slide along the supporting frame for magnetic the knife therebetween, whereby when a knife is put between the two magnetic boards, the magnetic boards with magnetism can attract the knife and clamp the knife tightly therebetween, when no knife is put between the two magnetic boards, the magnetic boards are separated due to same magnetic polarity repelling each other.
