2. Cutting along the length
A hacksaw (figure II.1) is used for cutting along the side of a horn while leaving the opposite side intact.
This sawing method should only be used on the convex middle section of the horn, as the figure shows, to prevent the saw-end from damaging the horn-tip.
The pistol-grip handsaw shown in figure II.2 is indicated for longitudinal cutting of the horn from any angle. In addition, this type of saw is very economical as broken hacksaw blades can be used.
A jigsaw, as shown in figure II.3, may be used for straight cuts through the widest part of the horn, where the internal diameter is large enough for the blade to reach its lowest point without coming into contact with the opposite side of the horn.
A hacksaw may be used when the horn is to be cut through its diameter, by applying the blade at right angles to the clamping device, as shown in figure II.4. In a mechanised workshop, this operation can be carried out rapidly using a bench band saw, as shown in figure II.5.
When the horn is flattened, as shown in figure II.6, straight cuts can be made by a hacksaw, a pistol-grip hand-saw, a jigsaw or a band saw.
