A purpose-built throwing knife typically measures between 12 and 15 inches long and weighs between 12 and 20 ounces. (Shorter, lighter knives are difficult to grip and don’t have enough mass to stick easily; longer, heavier knives require more muscle power than most people can easily muster.) Its particular length, weight, and balance allow you to throw it consistently and accurately.
This means it’s important to choose a good throwing knife of the correct size and weight. You might start with a medium-size, purpose-made throwing knife from a reputable company. I like the Cold Steel Pro Balance Thrower, which costs $35. Good-quality throwing knives are forged from heat-treated alloy steel, and they can last a lifetime.
Odds - Shots - Care - Target - Wood
To improve your odds of landing shots, you should take care when creating the target. I recommend that you build one from a soft wood like pine, with the grain running vertically to permit easier sticking. Don’t use a tree—repeated knife wounds can kill it.
