 the blade supported in the frame of the blade plate with support from the two side edges and the rear face; 
 the frame of the blade plate having a front face with a raised pressure ridge thereon providing pressure against the blade plate transferring said pressure through the blade plate to the rear of the face plate, and a rear face with an oval cam receiving opening therein; 
 the blade holder frame slideably engaged within a motor mount frame; 
 the face plate, stably fixed to the covering shell motor frame mount, with a slot in the face plate for allowing insertion of a nail of a primate to pass through the slot to a cutting area within the covering shell; 
 engaging the cam receiving opening in the rear face of the blade plate is the eccentrically rotating cam; 
 an electric motor connected to the cam through the drive shaft; 
 the motor configured to rotate the rotatable shaft, revolving the eccentrically revolving cam; 
 the eccentrically revolving cam configured to apply varying force against the cam-receptive opening in the rear face of the blade plate, thereby causing the entire frame of the blade plate to slide up and down within the covering shell, moving the blade plate parallel against a plane of the face plate. 
 
     
     
         7 . The device of  claim 5  wherein the blade plate further comprises an outwardly-sloped plane to catch and redirect nail clippings from behind the face plate to a front area of the face plate and each side edge having a) the notch or hole therein. 
     
     
         8 . The device of  claim 5  wherein an on-off switch is present on the covering shell to close a circuit allowing power to flow to the electric motor and each side edge having a) the notch or hole therein. 
     
     
         9 . The device of  claim 5  wherein the covering shell comprises a first top piece and a second bottom piece, and connection of the first top piece and the second bottom piece fixes the motor frame mount within the covering shell and provides space for the blade holder frame to slide unobstructed along a complete upward track and a complete downward track . 
     
     
         10 . The device of  claim 4  wherein the frame of the blade plate further comprises an outwardly-sloped plane to catch and redirect nail clippings from behind the face plate to a front area of the face plate. 
     
     
         11 . The device of  claim 5  wherein the second bottom piece has an indentation in front of and below the face plate, and a sliding tray inserted into the indentation to capture nail clippings from the outwardly sloped plane.
