The largest diameter (thickness) of a branch that the tool can handle.
The larger the maximum cut diameter, the more powerful this model, the lower the likelihood that a certain branch will be too tough for the tool. At the same time, note that to ensure high power, long handles and strong blades are needed, which accordingly affects the dimensions, weight and price. Therefore, it is worth choosing according to this parameter with a certain margin, but at the same time, this margin should not be too large.
As for specific figures, a maximum diameter
of 20 mm or less is considered relatively small, but it often turns out to be quite enough for simple work.
21 – 30 mm — the average value,
31 – 40 mm — above average, and in loppers the maximum thickness can
exceed 40 mm.
This feature means that one of the handles of the tool is able to rotate around the longitudinal axis. Only single-handed secateurs (see "Type") are equipped with
a rotary handle, and the purpose of such a device is to optimize the position of the handle during work. The fact is that when working with one hand, the user's fingers not only squeeze the handles, but in fact also try to turn one of them; so that the handle, which can be rotated, does not slip under the fingers. This provides added convenience and minimizes the chance of blisters.
