What is claimed is: 
     
         1 . An abrasion and cut resistant glove, comprising:
 a coating, the coating comprising a polymeric, elastomeric, or latex composition, wherein the coating has an EN abrasion level of 4.   
     
     
         2 . The abrasion and cut resistant glove of  claim 1  further comprising a knitted nylon liner, the knitted nylon liner being a 15 or 18 gauge liner. 
     
     
         3 . The abrasion and cut resistant glove of  claim 2  wherein the knitted nylon liner comprises a nylon 6 or nylon 66 yarn or blends thereof. 
     
     
         4 . The abrasion and cut resistant glove of  claim 3 , wherein the abrasion and cut resistant glove has at least one of an EN abrasion level of 4 or greater or an EN cut resistance level of 2. 
     
     
         5 . The abrasion and cut resistant glove of  claim 1 , wherein the coating is foamed. 
     
     
         6 . The abrasion and cut resistant glove of  claim 1  wherein the thickness of the coating is between 0.1 and 0.3 mm. 
     
     
         7 . The abrasion and cut resistant glove of  claim 2  wherein the polymeric, elastomeric, or latex composition further comprises at least one of natural polyisoprene, synthetic polyisoprene, carboxylated acrylonitrile butadiene, non-carboxylated acrylonitrile butadiene, nitrile-butadiene, polychloroprene, polyvinyls, butyl latex, styrene-butadiene (SBR), styrene-butadiene latex, styrene-isoprene-styrene (SIS), styrene-ethylene/butylene-styrene (SEBS), styrene-acrylonitrile (SAN), polyethylene-propylene-diene, water-based polyurethane, an anionically stabilized polymer composition, solvent-based polyurethane, or combinations or blends thereof. 
     
     
         8 . The abrasion and cut resistant glove of  claim 1  wherein the abrasion and cut resistant glove withstands greater than 10,000 revolutions in a Taber abrasion tester without failing or exhibiting coating peel off from the liner. 
     
     
         9 . The abrasion and cut resistant glove of  claim 1  wherein the glove is capable of withstanding greater than 20000 revolutions in a Martindale abrasion tester without reaching the end point of the test from the liner. 
     
     
         10 . A method for making an abrasion and cut resistant glove, comprising:
 applying a strong coagulant to a glove-shaped former;   applying a polymeric composition to the former, thereby disposing a coating onto the former and/or liner;   dipping the former having a coating thereon into a weak acid; and   dipping the polymeric layer into a strong coagulant.   
     
     
         11 . The method of  claim 10 , wherein the polymeric composition is foamed. 
     
     
         12 . The method of  claim 10 , wherein the weak acid comprises tricarboxylic acid. 
     
     
         13 . The method of  claim 10 , wherein the polymeric composition further comprises at least one of natural polyisoprene, synthetic polyisoprene, carboxylated acrylonitrile butadiene, non-carboxylated acrylonitrile butadiene, nitrile-butadiene, polychloroprene, polyvinyls, butyl latex, styrene-butadiene (SBR), styrene-butadiene latex, styrene-isoprene-styrene (SIS), styrene-ethylene/butylene-styrene (SEBS), styrene-acrylonitrile (SAN), polyethylene-propylene-diene, water-based polyurethane, an anionically stabilized polymer composition, solvent-based polyurethane, or combinations or blends thereof. 
     
     
         14 . The method of  claim 10  further comprising dressing the former with a fabric liner before applying a strong coagulant. 
     
     
         15 . The method of  claim 14  further comprising compacting the fabric liner before dressing the former with the fabric liner. 
     
     
         16 . The method of  claim 15  wherein the compacting step further comprises a hot washing process, whereby the surface of the liner yarn is modified to promote adhesion to the polymeric layer and increase abrasion resistance. 
     
     
         17 . The method of  claim 10  wherein dipping the polymeric layer into a strong coagulant is followed by a second dipping of the polymeric layer into a coagulant, a second dipping into a weak acid and a second dipping into a strong coagulant. 
     
     
         18 . An abrasion and cut resistant coating, comprising:
 a crosslinked nitrile polymer coating, and   wherein the polymer has an EN abrasion level of 4 or greater and/or is capable of exceeding 10,000 Martindale abrasion cycles before failure of the coating.   
     
     
         19 . The abrasion and cut resistant coating of  claim 18  wherein the coating has a thickness between 0.1 and 0.3 mm.
