I was working up in Dorset Ontario last week in the first snow fall of the season
I'd left my tools out over night and they were cold and difficult to hold.
This and the snow shadow the tools left was a reminder to me to use tools sparingly.
I prefer the look of a dry stone wall with a minimum of fresh cuts, chisel scars and hammer marks on the stones. If one leave s no trace of having used tools, carefully fitting the random shaped stones mostly as they come, the wall will have a very satisfying peaceful natural appearance
