  • DE-LJI-20 2005 008 482 describes a knife sharpening device in the form of a fish which is held by hand to draw a knife transversely to the longitudinal direction through a formed on the underside of the V-shaped grinding opening with therein abrasive sheets ,
  • additional functions are realized on the device.
  • the mouth of the fish is designed as a note holder.
  • On the back of the fish there are slits of various widths, with which glass can be broken. Due to the shape of the fish is a sufficient fixation of the device during grinding difficult to achieve. Accordingly, a bow-shaped additional part is attached to the fish, which serves as a handle and safety device to protect the hands.
  • a portable, hand-operated knife sharpener which has an elongate base body with a continuous planar support surface or base plate, in one half of which a handle is formed on the upper side, while in the other half V -shaped grinding openings are arranged with abrasive-coated side surfaces. Additional functions are not provided with this device. Due to the flat support surface slippage of the device on the surface during sharpening is easily possible, thereby endangering the hand and the sharpness result can be affected. Furthermore, a knife sharpener is commercially available from the company Zwilling under the type designation TWIN Sharp, which has a bow-shaped handle, which has surfaces for placement on a flat surface at both ends. At one end of the handle, a V-shaped body is formed which includes a V-shaped grinding opening with sharpening elements disposed therein. Even with this device slipping on the surface with the consequent disadvantages is possible.

  • the knife sharpener 10 is placed with the suction cup 30 in the position shown in Fig. 4 on a flat surface (35 in Fig. 5) and lightly pressed, so that the suction cup 30 rests with its suction surface completely on the base 35 , Then, the base body 1 1 or handle is pivoted to the side until the head 13 of the knife sharpener 10 with the support surface 24 touches on the pad 35. As a result, a powerful negative pressure is generated within the suction cup 30 by the pivoting mechanism 31, which fixes the knife sharpener 10 on the base and makes it insensitive to the transverse movements during sharpening. If the fixation is to be released again, the main body 1 1 is pivoted back into the starting position and the negative pressure is reduced, so that the knife sharpener 10 can be easily removed from the base.
  • the knife sharpener of the present invention can also be used on non-horizontal surfaces. So it can be used not only on tables or work surfaces, but also easily on walls or vertical surfaces such as refrigerator doors and the like.
  • the knife sharpener 10 is to save space, it can not only be supplied in a drawer, but it can also be attached to the latter vertical surfaces by means of a suction cup and is therefore always ready to hand.
