I am making tool (axe, pulaski, etc) sheaths. The first few I made are from 5-6 oz veg tan, and I am wondering what is the lightest weight leather that would be suitable for this? Since this is for a nonprofit organization, if I can reduce cost even a little that would be nice, but these are used for trail work (bucking/clearing logs, repairing trail, etc) in the PNW, so they need to be durable & functional.
TIA
