How To Throw Knives

By Ed Sackett

4 November, 1996


Throwing imparts two motions to a knife: forward motion and spin. Forward motion is required to get the knife from your hand to the target. Spin must be timed so that the knife is travelling point foremost when it strikes the target.

If you could throw without spin, knife throwing would be a much simpler skill, wouldn't it? No, it wouldn't, because the spinning motion gives the knife gyroscopic stability, just the way rifling stablizes a bullet.

Controlling the spin is the hardest part of knife throwing, at least for mere mortals like me. The key to controlling the spin of a thrown knife is consistency. Let me say that again: CONSISTENCY. Many budding amateurs have given up in despair because they failed to appreciate the need for consistency.

Achieving consistency begins with practicing each throw using the same grip, and throwing each time from the same distance from the target. The grips are outlined below. The correct distance for a given throw is determined by a little trial and error, helped out with a bit of arithmetic.


A knife is thrown either by the blade or by the handle. A blade grip is probably a little easier for a beginner, and it's how most people visualize knife throwing.

The vertical blade grip comes naturally and easily. Grasp the knife blade so that all four fingers come in contact with the steel when closed. The knife should be gripped far enough up that it can be controlled with an essentially relaxed hand. To test this, twitch the knife a few times to make sure that the hilt does not wobble uncontrollably. Many knife throwers grip with the point of the blade reaching as far as the first crease of the wrist. The thumb falls into a natural position with the ball resting on the flat of the blade, or alternatively (and especially with very wide blades), resting along the edge. During the throwing motion and through the release, the knife is held with the blade vertical, that is, with the edge toward the ground.

The flat blade grip is also used by some knife throwers, but chiefly for throwing short distances. This grip resembles the vertical blade grip, except that the blade is held parallel to the ground. This grip will tend to impart a more rapid spin to the knife. Because the knife strikes the target with the flat of the blade horizontal, there is less tendency to penetrate, especially if the angle of impact is not precisely perpendicular to the target. Also, because most targets are made of wood with the grain running vertically, a knife thrown with a flat grip will encounter more resistance from the target and will tend to penetrate less. Another, more minor disadvantage is that a knife flying flat-side-to through the air meets more air resistance, and will lose velocity over long distances.

A third type of blade grip, a variation of the flat grip, is used for throwing a knife with a sharp edge. In this grip, the flat of the blade rests against the ball of the palm. The tips of the fingers rest against the flat of the blade, as does the thumb on the opposite side. Thus the sharp edge never touches the hand. This grip is most comfortable as a flat grip, although a vertical blade grip can also be used. Since throwing knives should never be sharpened, this grip will seldom be called for.

The handle grip closely resembles the ordinary grip used when cutting. Grasp the knife with the full length of the handle in the palm, the fingers closing naturally. The thumb falls into position as in the vertical blade grip. Comfortable control without exerting much grip is the goal. During the throwing motion and through the release, the blade is held vertically.

Professional knife throwers always use vertical grips, whether by the blade or handle. Amateurs, and especially beginners, should remember this when experimenting with different methods of throwing.

Gripping the knife with all four fingers will impart a fairly slow spin. This is desirable for easier control. Within certain limits, a shallower grip will impart more spin. This is useful when throwing from uncertain distances. With practice, it's possible to use judgement to control the spin, through a combination of grip, stance, and arm motion, to stick knives at a variety of distances from the target. But it's frustrating to a beginner to try this, and I'll leave the topic for the chapter entitled "Variations and Stunts."


Assume a comfortable standing position facing the target, with the knees slightly bent and one foot advanced well ahead of the other. A right-hander should advance the left foot, a left-hander the right foot, but this is not a hard and fast rule. Grip the knife as described above. Using a natural overhand throwing motion with plenty of follow-through, pitch the knife swiftly at the target, aiming at a point just at eye-level. Release the knife as your arm reaches the horizontal, allowing the knife to slip smoothly out of your fingers. There must be no wrist movement at the moment of release. Try always to release the knife as straight at the target as possible, avoiding any yaw, which can make an otherwise well-thrown knife miss the aiming mark by three or four inches. The knife should be thrown hard enough to follow a flat trajectory to the target, but a violent throwing motion is undesirable.

Concentrate on using a true overhand motion, with as little sidearm as possible. This will take some conscious effort, especially when throwing a very heavy knife.

At first, avoid moving your feet during the windup. Placing your leading foot exactly on the mark for a given distance is essential for good practice, and you should develop the habit of taking up your position precisely. It's worth noting that professional knife throwers use this method of positioning. You may even find yourself taking a step backward as you wind up. Later, when you've had some practice at finding your distance, you can vary your throwing by taking a step forward during the windup. To get the hang of this, just start your windup a step back from your throwing mark, and make sure your leading foot comes down accurately on the mark as you throw. Stepping forward during the windup will help when throwing tomahawks and extra heavy knives.

Full follow-through is important, to avoid the common error of flipping, that is, of halting the throwing motion at the instant of release. This imparts too much spin to the knife for easy control. (This kind of throwing motion can be used at short distances when a quick spin is needed, but is not very useful for throws longer than a half-turn.)


In the half-turn throw, the knife is gripped by the blade and makes one half of a turn on its way to the target. Begin by standing approximately eight feet from the target, or a little less if you're of short stature. Throw using a blade grip. Watch closely how the knife lands. If the knife strikes point first and sticks, it was thrown from the correct distance. If the knife strikes with the point uppermost, this means that it did not spin far enough in flight. To correct this, move back a foot or eighteen inches and try again. If the knife strikes with the handle uppermost, this means that it spun too far in flight. To correct this, move forward a foot or eighteen inches and try again. When you find the distance from the target at which your knives stick consistently when thrown one-half turn in a way that's comfortable for you, mark the spot: drive a stake in the ground, build a cairn, hire someone to stand there with a flag, but mark that spot, and always practice half-turn throws from there.

Take the trouble to measure your half-turn distance with some care, because it's used to calculate your basic half turn, a handy unit for measuring all knife throwing distances.

Here's how to calculate your basic half turn. Let's say that you stand with your leading toe nine feet from the target when throwing a half turn. Now subtract the length of your arm at full stretch during the throwing motion, that is, at the point where the knife is released. This factor may be a little hard to estimate, but will probably be about three feet. Three subtracted from nine equals six, and so six feet is your basic half turn.


In this throw, the knife is gripped by the handle and spins through one full turn on its way to the target. To find your distance for a full-turn throw, multiply your basic half turn by two and add the length of your arm:

6 feet x 2 = 12 feet + 3 feet = 15 feet

Thus the correct distance to stand from the target for a full-turn throw is fifteen feet. Many people get puzzled over this little piece of arithmetic. "Why don't I double my half-turn distance and stand eighteen feet from the target?" they ask. Answer: because you have to allow for the length of your arm at full stretch.

I was puzzled by this myself for many years, and owe my enlightenment to Harry McEvoy of Grand Rapids, Michigan, the manufacturer of Tru-Bal throwing knives, one of the really good lines of throwing knife on the market.

Failure to take arm-length into account has led some writers on knife throwing into a curious error: the belief that a knife begins to spin faster after it's travelled a certain distance. If this were so, we'd have perpetual motion. Of course, the rate of spin of a thrown knife doesn't decrease as fast as its forward speed, so in a very long toss a knife would tend to spin more times over a given distance; but this factor can be dismissed at ordinary ranges.


This throw is made with a blade grip, as in the half-turn throw. The knife spins through one and one-half turns before striking the target. The correct distance is three times your basic half turn plus the length of your arm:

6 feet x 3 = 18 feet + 3 feet = 21 feet

This is quite a long distance to throw a knife, and should keep you busy learning for some time. But don't be afraid to try the


This is thrown using a handle grip, as in the full-turn throw. The knife spins through two full turns before striking the target. The correct distance is four times your basic half turn plus the length of your arm:

6 feet x 4 = 24 feet + 3 feet = 27 feet

This will require a powerful, precise throw.

Remember that the more times a knife spins on its way to the target, the more times any error will be multiplied. Remember also that a successful throw requires a combination of correct forward speed and correct spin. Within broad limits, the speed with which a knife is thrown does not affect the amount of spin. Thus a knife that travels too fast will not have time to complete the correct number of turns to strike the target point-first. Many a time have I pitched a sticker violently (usually in frustration over bad practice) and seen it strike point uppermost, because it reached the target too soon to spin far enough. At other times, I've thrown too gently and seen the knife spin too much and strike handle-first. Consistency, I said.

Remember also that the above formulas for finding the correct throwing distances are approximate. Many factors can combine to vary the theoretical throwing distances: slight changes in stance, the extra effort required to throw farther, the different spin given to a knife by handle vs. blade grip, etc. Use the formulas to get approximately the right distances. Then vary the distances a little by trial and error until you can throw comfortably, and mark your own personal throwing spots.

The blade grip seems to be a little more accurate than the handle grip, and it's usually favored by performers. Professional knife throwers use the half-turn throw (the shortest one) for particularly difficult and dangerous feats. They tend to use the turn-and-a-half throw for many of their other stunts. There's something really satisfying about a turn-and-a-half throw: the distance is great enough to offer some challenge, but not so great as to make throwing impossibly difficult. After you've learned to throw reasonably well in a variety of ways, you may settle down to steady practice at a turn-and-a-half.


When a knife doesn't stick in the target and stay there, the throw is a failure. In competitions, you get only a few throws, or even one throw, and the knife that fails to stick might as well have missed the target altogether.

Here's a little tip: Try to make your blade strike the target in a slightly handle-down attitude. The spin will tend to turn the knife deeper into the wood, embedding it solidly so that it stays put. A few degrees of handle-down is enough for most knives. But note the extreme Bowie type illustrated in the chapter "Knives." This knife is thrown exclusively with a handle grip, with the main edge uppermost. It's intended to strike the target with the handle as much as thirty degrees below the horizontal. That extremely curved Bowie point hooks into the wood and stays there. This design was given me by John Marotzke, who has won many a ham and turkey with his knife and tomahawk tossing in buckskinner competitions. He got it from a professional carnival performer; and the pros can't afford to have knives dropping out of the target any more than you can.
