A spear cut is a well-known technique for making a quick cut through small upward growing limbs and uprights, where the bar is angled to cut from the top, just slightly off vertical. The cut is raced through quickly so the piece drops straight down before the top starts to move, which causes the but to slide off the cut, as the piece drops like a stone without rotation. Calling this cut a spear cut is like calling a bowline-on-a-bight a bowline. That would be a mistake. We really need to be precise in our language or there is bound to be miscommunication. This cut uses a hinge and a notch. The notch and back cut are cut on steep angles, similar to a spear cut, but that doesn't make this a spear cut. This cut is called the stangle, which comes from the steep angle to the notch. Please get clear on the above distinctions and use proper terms. Thank you
