Oral care implement having multi-component handle

A method of forming a handle for an oral care implement, the method comprising:

• a) forming a core structure of the handle from a first hard plastic;
• b) forming an elongated handle body of a second hard plastic that partially surrounds the core structure so that opposing surfaces of the core structure remain exposed;
• and
• c) forming a grip cover of a resilient material over at least a portion of the elongated handle body,
• wherein steps a)-c) are performed by injection molding, the core structure being exposed also via through holes in the elongated handle body, and the through holes being formed by contact of the core structure with a gripping member of a mold during said forming of the handle body, and
• wherein outer arcuate ridges of the handle body extend into openings of the grip cover while remaining depressed below a rear surface of a rear leg of the grip cover, the grip cover filling transverse channels or slots between the outer arcuate ridges, and the grip cover contacting the core structure via the through holes.
