A Tomahawk dunk can be performed with one or two hands, and when two hands are used, it is called a backscratcher. During the jump, the ball is raised above, and often behind the player's head for a wind-up before slamming the ball down into the net at the apex of the jump. Due to the undemanding body mechanics involved in execution, the tomahawk is employed by players of all sizes and jumping abilities.[citation needed] Because of the ball-security provided by the use of both hands, the two-handed tomahawk is a staple of game situations—frequently employed in alley-oops and in offense-rebound put-back dunks.
A vertical jump is defined as the highest point an athlete can touch from a standing point jump, less the height the athlete can touch from a standing position (standing reach height). The best place to start with your vertical jump improvement is testing your vertical jump. This will serve as your reference point to see how you’re increasing your vertical.

A second, more efficient and correct method is to use an infrared laser placed at ground level. When an athlete jumps and breaks the plane of the laser with his/her hand, the height at which this occurs is measured. Devices based on United States Patent 5031903, "A vertical jump testing device comprising a plurality of vertically arranged measuring elements each pivotally mounted..." are also common. These devices are used at the highest levels of collegiate and professional performance testing. They are composed of several (roughly 70) 14-inch prongs placed 0.5 inches apart vertically. An athlete will then leap vertically (no running start or step) and make contact with the retractable prongs to mark their leaping ability. This device is used each year at the NFL scouting combine.
