Oscillating tool drywall blade

Abstract

An oscillating blade for cutting or shaping sheet materials such as drywall, with a blade, a sharing portion, a depth gauge for determining depth of cut, a caliper portion for premarking sheet materials for a standard dimension cut, and a reverse direction blade.

         9 . The oscillating blade of  claim 1 , wherein the shank includes a laterally outwardly extending shank extension. 
     
     
         10 . The oscillating blade of  claim 1 , wherein the shank includes a first portion having a first width and a laterally outwardly extending shank extension, and the shank extension has a width that is narrower than the first portion. 
     
     
         11 . The oscillating blade of  claim 1 , wherein the shank includes a first portion and a second portion, and includes a laterally outwardly extending shank extension joined to the second portion to define a piercing tip. 
     
     
         12 . The oscillating blade of  claim 1 , wherein the shank includes a first portion and a second portion, and a shank extension extends laterally outwardly from the second portion to define a laterally extending piercing tip. 
     
     
         13 . The oscillating blade of  claim 1 , and further comprising:
 a fixed caliper gauge joined to the shank.   
     
     
         14 . The oscillating blade of  claim 1 , and further comprising:
 a first marking tip joined to the shank; and   a second marking tip jointed to the shank, and spaced part from the first marking tip to define a fixed caliper gauge.   
     
     
         15 . The oscillating blade of  claim 1 , and further comprising:
 a first caliper tip joined to the shank adjacent to the blade; and   a second caliper tip joined to the tool mounting end, and spaced apart from the first caliper tip to define a marking caliper.   
     
     
         16 . The oscillating blade of  claim 1 , and further comprising:
 a first caliper tip joined to the shank adjacent to the blade; and   a second caliper tip joined to the tool mounting end, and spaced apart from the first caliper tip to define a marking caliper, the second caliper tip comprises:
 a piercing tip, and 
 an extreme marking edge spaced apart from the piercing tip. 
   
     
     
         17 . The oscillating blade of  claim 1 , and further comprising:
 a first caliper tip joined to and extending laterally outwardly from a shank extension; and   a second caliper tip joined to and extending outwardly from the tool mounting end.   
     
     
         18 . The oscillating blade of  claim 1 , and further comprising:
 a first marking tip joined to the shank; and   a second marking end portion joined to the shank and extending outwardly from the shank, and including a second marking tip joined to the second marking end portion, and the second marking tip is spaced apart from the first marking tip to define a marking caliper.   
     
     
         19 . The oscillating blade of  claim 1 , and further comprising:
 a reverse direction blade joined to the shank.   
     
     
         20 . The oscillating blade of  claim 1 , and further comprising:
 a dagger blade joined to and extending laterally outwardly from the shank.   
     
     
         21 . The oscillating blade of  claim 1 , and further comprising:
