DMM have tweaked the original design with a few modern improvements, such as a swage thats crimped on one side only, allowing one wire to run free and keep the head optimally loaded.
The silicon brass used for the head is specifically chosen for its hardness to strength ratio, meaning it will be soft enough to 'bite' on the rock, but not be too soft and shear. Every unit produced is also proof loaded to 75% of its rated strength before DMM let it go.
Each Brass Offset has a colour coded alloy swage, meaning size selection is made more straight forward.
