While you can use the Woox Thunderbird Throwing Axe for general “axe activity” like chopping and carving, as the name implies, it’s optimized for flight. The handle is smooth to allow a predictable and hang-up-free release. There’s no discernible palm knob at the base of the handle. On a utility axe, you’ll almost always have some handle mass (palm, swell or end knob) designed to prevent your hand from sliding off the end of the handle. For throwing, you want the Thunderbird to slide right through your fingers as you release each toss — hence no palm knob.
