The presence of an additional pad (pads) made of rubber in the design of the ax handle.
Such overlays are used for additional convenience and safety at work. Firstly, the rubber does not tend to slip in the hand, which reduces the risk of releasing the tool. Secondly, this material is soft and pleasant to the touch, and also does not "cold" hands in cool weather. Thirdly, the rubber dampens the vibrations of the handle, increasing the accuracy of work and reducing fatigue (this is perhaps the main advantage of such overlays).
Handles made of almost any material can be
rubberized(see above), however, for a number of reasons, rubber is rarely combined with wood.
The presence of a
sheath in the kit of the tool greatly simplifies storage and transportation: the sheath at least protects the blade from contact with foreign objects (which could lead to damage to these objects or the blade itself). At the same time, a complete case is more convenient, and often safer, than a case “from improvised materials”.
A full-fledged case is considered as such a case, in which the tool is placed entirely or almost entirely, and not an overlay on the blade.
