Short Blade

Group

短刀術(Tantō-jutsu)

Traditional

Translation: short blade

Overview

The Short Blade group encompasses all combat techniques employing edged weapons shorter than a standard sword, including knives, daggers, and tantō. ^[1] Short blades have been carried as secondary weapons by warriors across virtually every martial culture, from the medieval European rondel dagger to the Japanese tantō and the Filipino balisong. ^[1],[2] Because short blades require the user to fight at extremely close range, the techniques in this group emphasise rapid transitions between offence and defence, ambidextrous use, and integration with empty-hand grappling. ^[2],[3] Short-blade combat is studied today in HEMA dagger programs, Filipino martial arts knife curricula, Russian Systema knife work, and traditional Japanese tantō-jutsu, making it one of the most broadly practised weapon categories worldwide. ^[3],[4] The group is divided into three families — HEMA Dagger, Knife Fighting, and Tantō-Jutsu — reflecting the major cultural lineages of short-blade use. ^[4]

History & Origin

Short blades are among the oldest purpose-built weapons, with flint daggers dating to the Neolithic period and bronze daggers appearing in Mesopotamia by approximately 3000 BCE. ^[1] In medieval Europe the dagger served as a sidearm for armoured knights, leading to a sophisticated corpus of dagger techniques recorded in fight-books such as Fiore dei Liberi's Fior di Battaglia (1409) and Hans Talhoffer's Fechtbuch (1467). ^[1],[2] In Japan the tantō was carried by samurai as a last-resort weapon and was the subject of dedicated tantō-jutsu curricula within classical koryū schools. ^[2],[3] Filipino martial arts elevated knife fighting to a primary discipline, with systems like Pekiti-Tirsia Kali and Sayoc Kali building entire curricula around the blade. ^[3],[4]

Effectiveness

Short blades (knives, daggers, tantos) excel at close-range combat where their concealability and speed compensate for limited reach. ^[1]

Lineage

Short blade fighting exists in virtually every martial tradition, from Japanese tantōjutsu to Filipino dagger to HEMA dagger, reflecting the universal utility of the knife as a weapon. ^[1],[2]

Competition Record

Short blade competition exists in FMA dagger divisions, HEMA dagger events, and koryū tantōjutsu demonstrations. ^[1]

Biomechanical Mechanism

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

Position & Entry

From ready stance (chudan-no-kamae or equivalent) — Assume guard position, establish distance (ma-ai), execute the cut or thrust when an opening appears

From engagement distance — Use footwork to close to striking range, execute the technique with proper edge alignment (hasuji)

As counter — Wait for the opponent's attack, deflect or avoid, and counter-cut to the exposed target

Training Notes

✓Short blade arts encompass knife fighting, dagger techniques, and tanto-jutsu — weapons under 18 inches that fight at close quarters (Amberger, The Secret History of the Sword, 1999)

✓Short blade combat occurs at a range where empty-hand and weapon techniques overlap — creating a uniquely dangerous environment

✓The knife is the most commonly encountered weapon in real-world self-defence situations — understanding blade mechanics is practical knowledge

✓Short blade arts teach two fundamental grips: forward grip (sak-sak, hammer grip) and reverse grip (pakal, ice-pick grip) — each has distinct advantages

✓Historical European dagger fighting (HEMA) was a sophisticated art: Fiore dei Liberi's treatise dedicates extensive sections to dagger combat

✓The tanto (Japanese short blade) is used in aikido, jujutsu, and classical koryu arts as both a weapon and a training tool for distance and timing

✓Short blade fighting principles: control the weapon hand first, maintain reactionary gap, and understand the lethal geometry of edged weapons

Common Mistakes

!Underestimating the danger of short blade combat — even training should treat blade distances with extreme respect

!Not controlling the weapon hand as the first priority — the weapon hand must be managed before attempting any technique

!Training knife techniques at unrealistic distances — knife fighting occurs at extremely close range

!Ignoring the reverse grip — both forward and reverse grip have applications; train both

!Not understanding lethality — short blade training must include awareness of the real consequences of edged weapon encounters

!Training only offence without defence — blade defence (evasion, redirection, disarming) is equally important

!Using excessive movements — short blade techniques are small, fast, and efficient; large movements are dangerous

Related Techniques

Guard Position — the ready stance from which this technique is initiated

Counter Techniques

Parry (Absetzen) — deflect the incoming blade with a counter-displacement Void (Step Back) — withdraw from measure to avoid the cutting arc Counter-Cut (Nachreisen) — strike into the opponent's opening during their attack

Setup Chain

1Assume Guard (Kamae/Hut) — take the appropriate ready position with the weapon

2Measure Distance (Ma-ai) — establish correct striking distance

3Initiate Cut/Thrust — execute the technique with proper edge alignment or point control

4Follow Through (Zanshin) — maintain awareness and readiness after the technique

Sub-techniques

Dagger — HEMA

Family

The Dagger (HEMA) family covers the European historical dagger combat techniques preserved in medieval and Renaissance fight-books. [1] HEMA dagger fighting is characterised by its integration with armoured combat (Harnischfechten), where the dagger was the weapon of choice for dispatching a downed opponent through gaps in plate armour. [1,2] Techniques include thrusts to vulnerable points such as the visor, armpits, and groin, along with disarms, locks, and throws that blend seamlessly with wrestling (Ringen). [2,3] Major sources include Fiore dei Liberi's Fior di Battaglia, which devotes an entire section to dagger (daga), and the German Fechtbücher of Hans Talhoffer, Paulus Kal, and Codex Wallerstein. [3,4]

Knife Fighting

Family

The Knife Fighting family covers combat systems that employ a single-edged knife as the primary weapon, spanning traditions from Filipino martial arts to Russian military knife combat and modern self-defence curricula. [1] Unlike dagger techniques that are primarily thrust-oriented, knife fighting encompasses a full range of cuts (slashes, backhand cuts, upward cuts), thrusts, grip changes, and defensive disarm techniques. [1,2] Filipino martial arts — particularly Pekiti-Tirsia Kali, Sayoc Kali, and Balintawak — have produced the most technically elaborate knife-fighting curricula, organising techniques around angles of attack and fluid grip transitions. [2,3] Knife fighting is also studied within Krav Maga, the Russian Systema, and various military combatives programs as a practical close-quarters combat skill. [3,4]

Tanto-Jutsu

Family

Tantō-jutsu is the Japanese art of fighting with the tantō, a single-edged blade typically measuring 15–30 cm (6–12 inches). [1] Within classical Japanese martial arts (koryū), tantō-jutsu encompasses both offensive techniques (thrusting, slashing) and defensive applications (tantō-dori, or knife-taking, where the unarmed defender disarms a knife attacker). [1,2] The tantō held deep cultural significance in Japanese warrior society as the weapon of ritual suicide (seppuku) and as a concealed self-defence weapon carried by both samurai and women of the warrior class. [2,3] Tantō techniques are preserved within several koryū traditions including Takenouchi-ryū, Yagyū Shingan-ryū, and Shindō Musō-ryū. [3,4]
