AB  - The forensic investigator is frequently confronted with the discrimination and 
      deduction of injury implements, which is one of the most important physical 
      testimonies in courts. The usual method used in actual cases is from points of 
      morphology. In the forensic discrimination of injury implements, such as metal 
      implements, the analysis and comparison of elements are expected to provide 
      excellent results, and simultaneous multi-elemental analysis is required to 
      analyze various kinds of elements. This study was designed to establish 
      discrimination and deduction of metal injury implements by scanning electron 
      microscope/energy disperse X-ray microanalyzer (SEM/EDX) and inductively coupled 
      plasma atomic emission spectrometry (ICP-AES). Examined metal particles in five 
      wounds made on the skin of domestic pigs, respectively, using Cu-Zn or Cr-Ni 
      coated and carbon steel kitchen implements by EDX. For carbon steel kitchen 
      implements, analyzed five samples from the back and blade separately in the 
      contents and varieties of elements by ICP-AES. In the wounds by the coated 
      implements, the special particles only containing Cu, Zn or Cr, Ni were found. In 
      the wounds by carbon steel kitchen implements, the particles containing Fe, Cr, 
      Si or Fe, Mn, Si were found. The differences of contents of elements between the 
      back and blade was no significant except No. 5 for carbon steel kitchen 
      implements, and the significant differences of elements exited in Cr, Mn, Si, Cu, 
      Mo among the stainless kitchen knives, Mn, Si among the other kitchen implements 
      and for the blade of No. 5 knife, relative standard deviations (R.S.D.s) were 
      significantly different in Mn, Si, Mo, Ti, S, P, Ni. Using EDX to examine the 
      particles in wounds can deduce the categories of metal injury implements, and we 
      can still deduce the different implements in the same category by ICP-AES.
