The ergonomic shape of the oiled plywood allows for sawing at many different angles without twisting the wrist. 

The design also allows for delicate cuts on smaller plants as well as powerful strokes on larger branches.

Normal: with the index finger through the handle's hole the upper arm muscle takes the strain of the pulling action. On the push stroke, the thumb has a counter pressure point on the top of the handle and the power comes from the pectoral muscles.

Smaller branches: with the index finger on the top of the handle and middle finger through the hole, there is less pressure on the branch and greater accuracy.

Larger branches: using the pistol grip allows more pressure to be exerted making for a more effective cut without using much force.

Undercut: no need to twist the wrist when cutting a branch from below; turn the saw over and cut with the index finger through the hole and the remaining fingers gripping what is normally the top edge.

Stretched: the small spur at the end of the handle still allows a good grip when stretching to reach a branch.
