Обзор
The Standard Spear Sweep executes the fundamental shaft strike by sliding the grip position and swinging the butt end or mid-shaft in a horizontal or diagonal arc to strike the opponent's legs, midsection, or weapon, or to sweep their weapon aside to create an opening for a follow-up thrust. [1] The standard sweep uses the same body mechanics as a staff strike — hip rotation driving the shaft through the target — and can be directed at the opponent's lower legs to trip, at the hands to disarm, or at the weapon shaft to deflect. [1],[2] Following the sweep, the practitioner typically recovers to a thrusting position, using the sweep as a set-up for the spear's primary weapon: the straight thrust. [2],[3]
История и происхождение
Standard spear sweep techniques are part of the comprehensive sojutsu curriculum found in koryu schools, representing the shaft-based component of Japanese spear fighting that complements the dominant thrusting method. [1] The sweep-to-thrust combination is one of the most effective tactical sequences in sojutsu. [2],[3]

Биомеханический механизм
Primary Action — Cutting, thrusting, or striking with a bladed weapon — edge alignment and trajectory determine cutting effectiveness
Joints Involved — Wrists (edge alignment and rotation), elbows (extension for thrusts, chambering for cuts), shoulders (arc of the cut), hips (power generation)
Force Vector — Varies — downward diagonal cut (kesa-giri), horizontal cut (yoko-giri), thrust (tsuki), or rising cut (kiri-age)
Weapon Mechanic — Edge alignment (hasuji) is critical — the blade must travel along its cutting plane for effective cuts
Позиция и вход
From ready stance — Hold the staff in two-handed grip, establish distance, strike with the end or middle section as appropriate
From defensive position — Use the staff to block or deflect the incoming attack, then counter with a strike or thrust
Варианты
Overhead strike — bringing the staff down from above in a vertical arc
Lateral strike — horizontal sweep targeting the ribs or head
Thrust — straight thrust with the end of the staff
Butt-end strike — striking with the rear end of the staff at close range

Что говорят инструкторы
The standard spear sweep, known in wushu competition as the ho-sau-twe or back sweep, is a fundamental technique evaluated under Code 21 deductions in international wushu judging. According to Brandon Sugiyama (invibe), judges assess this technique using two strict criteria: the sole of the sweeping foot must maintain contact with the ground throughout the entire movement, and the sweeping leg must remain straight from initiation through completion. A bent leg is defined as any visually perceptible deviation from straightness, regardless of degree. The foot leaving the ground—even intermittently—constitutes an infraction. Sugiyama emphasizes that Code 21 deductions are preventable through focused technique practice rather than dynamic enhancement, distinguishing them from other deductions rooted in execution errors. The technique is common in compulsory forms across multiple wushu styles and schools. Judges do not evaluate the sweep based on rotation completeness, body height, or speed; only ground contact and leg straightness matter. The first instructor (taichikungfu99) provides no intelligible technical instruction in the available transcript.

Заметки по тренировке
✓The standard spear sweep uses a horizontal shaft rotation to push the opponent's weapon aside, immediately followed by a direct thrust to the exposed centre line (Draeger, Classical Bujutsu, 1973)
✓Execution: from the middle guard, rotate the shaft horizontally against the opponent's weapon — knocking it to the side using the shaft's leverage
✓The sweep contacts the opponent's weapon at the mid-shaft point — using the maximum leverage of the spear's length
✓The sweep-to-thrust must be one continuous motion — the sweep clears the path and the thrust exploits the opening without pause
✓The sweep uses minimum force — only enough to displace the opponent's weapon; excessive force swings the spear too far for a quick follow-up
✓The hands adjust during the transition: after the sweep, they reposition for the thrust — the grip shifts fluidly
✓The standard sweep works against any weapon the opponent holds — the horizontal displacement is effective regardless of the defending weapon type
✓In formation fighting, the standard sweep was used to create openings in the enemy's front-line defences for the rank behind to thrust through
Типичные ошибки
!Sweeping with too much force — excessive force makes it difficult to transition quickly to the thrust
!Pausing between sweep and thrust — the sweep-thrust must be continuous; any pause allows the opponent to recover guard
!Not contacting the opponent's weapon at the optimal point — contact near the centre of their weapon provides maximum displacement
!Sweeping in the wrong direction — sweep the opponent's weapon to the outside (away from their centre) for maximum effect
!Not adjusting the grip for the thrust — the hands must shift smoothly from sweep mechanics to thrust mechanics
!Using only the blade end for sweeping — the shaft is the sweeping tool; the blade is preserved for the thrust
!Attempting the sweep from too far away — the shaft must reach the opponent's weapon; distance must be appropriate

Часто задаваемые вопросы
What is a Code 21 deduction in wushu competition, and how does it relate to the spear sweep?
A Code 21 deduction (ho-sau-twe) is a judging penalty applied when a spear sweep is performed with technical errors. Brandon Sugiyama (invibe) explains that the two main errors judges look for during a spear sweep are improper foot positioning—specifically when the sole of the foot is not parallel to the ground but instead faces laterally toward the judges.
Why do athletes make mistakes during the spear sweep in competition?
According to Brandon Sugiyama (invibe), Code 21 deductions are typically caused by habit and bad technique rather than random errors, and can be fixed through focused practice and proper form.
