Abstract: A foodstuff slicer and server, comprising an integral band made of a rigid material, the band having three equally spaced transverse hinges and forming a lozenge structure defining a first pair of transversely opposite sides which constitute cutting blades, and a second pair of transversely opposite sides which constitute handles. A coil spring is secured to the handles to bias the angle of the cutting blades to a predetermined maximum value. Upon cutting foodstuff in a sector piece with the blades, the handles may be drawn one toward the other against the bias of the coil spring, first to determine the size of the foodstuff to be sliced, then to slice the foodstuff. Then the handles are slightly further drawn towards each other to secure the sector piece of foodstuff for transporting same. The sector piece of foodstuff is released upon release of the handles.

Abstract: A concentration aid for strung rackets used in various sports wherein the object is to hit a projectile, comprising a racket having a head portion provided with a netting matrix, and a handle; a bead made of rigid aesthetic material and having a through-bore. The bead is located in one of the as square openings of the "sweet spot" area of the netting and is held in place by a pair of strings under slight tension and passing through the through-bore and extending on either side thereof, having their opposite ends fastened to the racket frame or to the matrix netting. A projectile striking the bead produces a distinctive vibration felt in the player's forearm thereby helping him or her to properly localize the "sweet spot". The bead does not deviate the trajectory of the projectile on either forehand or backhand strokes of the racket since it is free to retract within the netting opening when struck by the projectile.
