The usability and ergonomics of axes.

This study evaluated the ergonomics and usability of axes. Several methods were used, namely measurement of impact velocity, the determination of kinetic energy, splitting performance tests, durability tests of blades and handles, and user trials. The mean velocity used in the striking was 9.6m/s (8.9-10.3m/s, SD 1.5). In the durability tests, the blades withstood the test reasonably well. In the bending tests, there were differences in the durability of the handles, which related to their material. A wide variation in the durability of the axe handles was also observed. User trials were conducted to evaluate the various features of the axes.
