*Notes on No-Spin

The 3 targets are set to be thrown from left to right. Standard IKTHOF targets will be used along with traditional scoring with 5 points awarded to the center bulls-eye, 4 to the peripheral octagon, etc.
The knife must be thrown with a “No-Spin” technique, which means it completes an approximate ¼ rotation or less. In some cases, the knife’s handle will lead the knife on release. This is technically a larger rotation than a ¼ spin but since the knife was held by the handle, it is considered a no-spin or ¼ spin throw and is permissive. Since there are several techniques in performing a no-spin upon release, as long as the knife is held by the handle, and hits the target point first without a rotation greater than described above, it is permissible.

Knives

Three (3) identical knives are needed for this event. The knives and the competitor’s technique will be approved beforehand by the Range Master on a practice lane to make sure the competitor’s technique is acceptable, safe for viewers/competitors and that the knives stay within the following rules:
The knives used will not exceed 16” (40.64cm) long from tip to handle.
The minimum length is 10” (25.4cm) from tip to handle.
The minimum weight is 8oz (226g).
Bo Shuriken or Spikes longer than 10” (25.4cm) and less than 16” (40.64cm) in length and at least 5oz (141.7g) in total weight are also permitted and encouraged. If the knife is untraditional or in question, the Range Master must approve the knife before the competition.
Handles are permitted on knives, Bo Shuriken and Spikes. Any material is acceptable: Tape, Sports Wrap, Paracord, and Twine with Epoxy coat, etc.
*Gyro knives, Flying Knives, or any other knife that allows air to pass through the handle to hinder spin is not permitted. Fletching, tassels, are also not permitted. In addition, a length of cordage or chain cannot be attached to the knife to be thrown like a rope-dart. Short spears are not permitted. The regulations for this event define a spear as over 13” (33.02cm) in length with a point/blade which length makes up for less than a third of the implements overall length.

Grips

The knife will be gripped by the handle. The point of the blade upon release is either pointing upwards or slightly toward target. At further distances, the point of the blade may be slightly beyond the 12:00 position (Technically, slightly above a ¼ spin). The knife can be held or palmed as high on the blade as one desires. However, the thrower is not permitted to touch the last inch of blade closest to the point when throwing. While not encouraged, the knife can be pinched in the same manner as one would pinch a spear.
*Note that sidearm releases are permissible.
*Note that underhand releases are NOT permissible.

Distances

The thrower must throw behind these respective lines:
2m (6’7”), 3m (9’10”), 4m (13’1”), 5m (16”5”) and 6m (19’8”).
If the competitor steps over the set boundary line, he will be warned by the lane official. If it happens again, the score for that throw will be zero (no score) regardless of the knife’s impact. If the competitor executes a sidearm throw, he is allowed to straddle the boundary of the lane but one foot must remain within the lane and behind the set distance. This must be done in a way that does not interfere with another competitor and if this proves to be too distracting he can allow the other thrower to proceed so there is a free lane to his left. If a competitor needs to step forward on each release, they are permitted to do so, as long as the final step is within the set boundary line.

Style

No-Spin is an instinctive style of throwing and has a variety of ways to perform the technique. Release, stance, arm motion, arm position and body movement and grip will vary. As long as the competitor stays within the defined rules and regulations as described above, we encourage you to have fun!
