## Abstract

There is provided a culinary whisk comprising one or more wire loops for mixing foodstuffs, the or at least one of the wire loops includes an inner metallic wire portion and an outer polymeric portion enclosing the inner portion, wherein the inner portion is provided with groove(s) along substantially the length thereof for increasing frictional contact with the outer portion or means for fixedly adhering the outer portion to the inner wire portion whereby in use relative movement between the external portion and the internal portion is reduced.

## Claims

### Claim 1

A culinary whisk comprising at least one wire loop for mixing foodstuffs, said at least one wire loop including:
an inner metallic wire portion having a groove along a length thereof;
an outer polymeric portion enclosing said inner metallic wire portion; and
an adherer positioned and configured to adhere said outer polymeric portion to said inner metallic wire portion,
wherein the groove is positioned and configured to increase frictional contact with said outer polymeric portion and thereby in use to reduce relative movement between said outer polymeric portion and said inner metallic wire portion.

### Claim 2 (depends on 1)

A whisk as claimed in claim 1, wherein said inner metallic wire portion is made of stainless steel.

### Claim 3 (depends on 1)

A whisk as claimed in claim 1, wherein said outer polymeric portion is made of silicone.

### Claim 4 (depends on 2)

A whisk as claimed in claim 2, wherein said outer polymeric portion is made of silicone.

### Claim 5 (depends on 1)

A whisk as claimed in claim 1, wherein said groove is positioned in a spiraling manner along the length of said inner metallic wire portion.

### Claim 6 (depends on 2)

A whisk as claimed in claim 2, wherein said groove is positioned in a spiraling manner along the length of said inner metallic wire portion.

### Claim 7 (depends on 3)

A whisk as claimed in claim 3, wherein said groove is positioned in a spiraling manner along the length of said inner metallic wire portion.

### Claim 8 (depends on 1)

A whisk as claimed in claim 1, wherein said whisk is a balloon whisk.

### Claim 9 (depends on 1)

A whisk as claimed in claim 1, wherein the at least one wire loop comprises six wire loops.

### Claim 10 (depends on 1)

A whisk as claimed in claim 1, wherein said whisk is of an elongate profile with said at least one wire loop positioned at one end of the whisk and a handle positioned at an other end of the whisk.

### Claim 11 (depends on 10)

A whisk as claimed in claim 10, wherein said at least one wire loop is partially received within and secured to said handle.

### Claim 12

A method of making a culinary whisk comprising steps of:
providing a metallic wire;
introducing at least one groove on said metallic wire;
introducing an adhesive agent for bonding a polymeric jacket to the wire;
providing the polymeric jacket on said metallic wire to form a jacketed wire and for adhering the jacket to the wire by the adhesive agent;
forming wire loops out of the jacketed wire, and
securing said wire loops to a handle forming said culinary whisk,
wherein the at least one groove on the metallic wire is positioned and configured to increase frictional contact with the polymeric jacket on the wire and thereby in use to reduce relative movement between the polymeric jacket and the metallic wire.
