One more plus for the Alu handles.....
... this morning at 6am, in minus 1 temperatures I was repairing an electric fence voltage converter in a field, in the dark.
My torch was drawing heat from my hand something fierce, making it feel frozen and numb, but the handles on my AL were nowhere near as cold, and actually warmed to my hand.
In a similar circumstance, when I only had the Xti, it stayed cold.
The only thing is.....

.... I do seem to have a chunk of black missing off my handle now, I noticed earlier.
It's purely cosmetic, and only small, but I was only just on here proclaiming it bombproof!
