The simplest way to reduce the stress on your hands of long hours of sawing is to increase the diameter of the saw’s handle.
Which is where the new American made Comfort Grips come in: they increase the diameter of the saw’s handle without adding weight, while they also make the handle softer and easier to hang onto. All of which reduces hand stress and fatigue.
They just slip over the existing handles of the MK3 and MK4 saws. They take about 15 seconds to install, by sliding them on.
