Razor cartridge with non-cutting element
A novel razor cartridge includes at least one non-cutting element disposed anywhere within a blade array between a guard and a cap and/or in a blade position of a frame providing skin/hair management. This non-cutting element allows the fine-tuning of parameters such as blade-skin contact, hair orientation, blade spans and rinse-through gaps in manners that improve shaving comfort, closeness, efficiency, and/or rinse-ability. The non-cutting element may include projections, fin-like elements, comb-like features having teeth, exfoliation or lubricating capabilities. By having a fixed non-cutting element disposed midway in a blade array, a multi-stage cartridge is provided with a middle control point with potentially different functionality before and after the non-cutting element. The non-cutting element is not attached to another blade in the blade array though it may be manufactured as a modified blade support, attached to a blade support, or as part of the frame or the clips.
Method of making a bent razor blade
A method for making a bent razor blade is disclosed. The method includes: providing an elongated strip of stainless steel that can be 0.076 mm thick; hardening the strip; providing a cutting edge along an edge of the strip and providing coating(s) on the cutting edge. The stainless steel has a carbon content less than 0.60% and preferably between 0.45% and 0.55% by weight. The strip is separated lengthwise into discrete razor blades. The bent portion of the razor blade is then formed using a swivel bending process.

Process for producing a shape memory spiral rotary file
A method for manufacturing at least one nonlinear file including the steps of deforming at least a portion of a linear file away from a file axis and heat-treating the deformed file to shape-set the nonlinear file.
