Tool marks
			 
			 
			
		
		
		
			
			Any thoughts on what would create these marks? I would normally suspect a power tool, but these appear to be old and limited in area impacted.  This is a Kachin style dha marked with the "running tiger" stamp that has been attributed to HuSa on this forum. Where human-powered sharpening wheels in use in early 20th C in this region?
