<p>A comb or like grooming implement has a back and generally parallel integral teeth each of a rounded cross-section which is at least as wide as it is thick. A preferred cross-section is circular, and such circular teeth with an inner portion of greater diameter than a (preferably tapered) outer portion, and with a smooth transition region, are preferred. Such combs are more resistant to breakage and more effective in combing difficult hair.</p> |
