Profile: Hav-Roc, Inc. produces saws. We develop and build prototypes. Our treesaw is used to clear underbrush without damaging or removing prime trees and to clear roadways or right-of-ways through timberland. We offer V-shaped flexible blades and cutting teeth, which are made from a high-tensile alloy steel and the teeth are tipped with a hard-surface material to add hardness for wear-ability.
