hello everyone tonight
This might be a little off topic but frozen hemlock knots are notoriously hard and can actually ruin the cutting edge of an axe, especially those with hard tempering, and filed to a slim taper used mainly for chopping and scoring
As I was growing up and working with my dad in the bush and we happened to be limbing a hemlock on a real cold day I would be cautioned to use the poll of the axe to strike and break off the limbs rather than chopping them off as a precautionary measure
I had actually seen axes ruined by the frozen knots
enjoy
