Stag is durable enough for most purposes, but can sometimes be rough on the hands. It also may crack or chip if dropped on a hard surface.
Stacked leather, however, makes a great handle. If properly maintained, leather provides good grip, will not hurt the hands, and will not crack or chip. Most leather handles are manufactured in a way that makes them very resistant to the elements. Ka-Bar and Marbles have successfully used stacked leather handles on their knives for many years.
