         2 . The hair removal device of  claim 1 , wherein the body of the outer disc comprises a central hub and at least one arm extending radially from the central hub, wherein the peripheral surface is the radially, outermost surface of the at least one arm. 
     
     
         3 . The hair removal device of  claim 2 , wherein the at least one arm comprises an inner section, wherein the axial dimension of the peripheral surface is greater than an axial dimension of the inner section of the at least one arm. 
     
     
         4 . The hair removal device of  claim 3 , wherein the axial dimension of the peripheral surface is at least two times greater than the axial dimension of the inner section of the at least one arm. 
     
     
         5 . The hair removal device of  claim 3 , wherein the material forming the peripheral surface of the at least one arm is a polymer material. 
     
     
         6 . The hair removal device of  claim 5 , wherein the material of the inner section of the at least one arm is a metal. 
     
     
         7 . The hair removal device of  claim 2 , wherein the axial dimension of the at least one arm increases as the radial distance from the center of the outer disc increases. 
     
     
         8 . The hair removal device of  claim 7 , wherein the axial dimension of the at least one arm reaches a maximum at the peripheral surface. 
     
     
         9 . The hair removal device of  claim 1 , wherein the peripheral surface is a skin contacting surface and is configured to reduce discomfort associated with hair removal. 
     
     
         10 . The hair removal device of  claim 1 , wherein the inner disc and the outer disc include opposing surfaces configured to engage a hair. 
     
     
         11 . The hair removal device of  claim 10 , wherein the opposing surfaces of the inner disc and outer disc are substantially parallel to the radial axes of the discs, and the peripheral surface is substantial perpendicular to the radial axes of the discs. 
     
     
         12 . The hair removal device of  claim 10 , wherein the outer disc moves toward the inner disc to engage the hair. 
     
     
         13 . The hair removal device of  claim 1 , further comprising an insert coupled to the outer disc and positioned between the inner disc and the outer disc, wherein the inner disc includes a first surface and the insert includes a second surface opposing the first surface, wherein the insert and the inner disc are configured to engage a hair between the first and second surfaces. 
     
     
         14 . The hair removal device of  claim 13 , wherein the peripheral surface of the outer disc is made from a first material and the second surface is made from a second material. 
     
     
         15 . The hair removal device of  claim 14 , wherein the first material is a polymer material and the second material is a metal. 
     
     
         16 . The hair removal device of  claim 14 , wherein the first surface is made from the second material. 
     
     
         17 . The hair removal device of  claim 13 , wherein the outer disc includes an inner axial surface and an outer axial surface, wherein the insert is directly coupled to the inner axial surface of the outer disc. 
     
     
         18 . A hair removal device comprising:
 a housing;   an inner disc rotatably mounted to the housing, the inner disc including a first hair engagement surface; and   an outer disc rotatably mounted to the housing adjacent the inner disc, the outer disc comprising:
 an inner axial surface; 
 a peripheral surface positioned to contact skin of a user; and 
 an outer axial surface; and 
   an insert coupled to the inner axial surface of the outer disc, the insert including a second hair engagement surface facing the first hair engagement surface;   wherein the peripheral surface of the outer disc is made from a first material and the second hair engagement surface is made from a second material   
     
     
         19 . The hair removal device of  claim 18 , wherein the first material is a polymer material and the second material is a metal. 
     
     
         20 . The hair removal device of  claim 18 , wherein the first hair engagement surface is made from the second material. 
     
     
         21 . The hair removal device of  claim 20 , wherein the second material is metal. 
     
     
         22 . A method of removing hair comprising:
 rotating an inner disc and a pair outer discs of a hair removal device to cause the distance between opposing surfaces of the inner disc and outer discs to decrease;   grasping a hair between opposing surfaces of an inner disc and outer discs;   contacting the surface of the skin on either side of the hair with peripheral surfaces of the outer discs; and   resisting upward deformation of the skin during hair removal via the contact between the peripheral surfaces of the outer discs and the skin.   
     
     
         23 . The method of  claim 22  wherein discomfort is reduced by resisting upward deformation of the skin during hair removal.
