My first Moro Kris stain attempt
			 
			 
			
		
		
		
			
			The blade did not really look all that good after I finished polishing it, but some interesting patterns appeared when I wiped it with a mixture of vinegar and PCB (ciruit borad etchant).  
 
Not so sure I like the colors, but some interesting patterns. What can I do to make this better?
