Cutting discs were a type of small rotating weapon usually prevalent in the original series of Robot Wars. They were specialised to cut, slice and tear into other robots, targeting their armour, wheels/tracks, aerials, batteries and other sensitive components, and were capable of causing severe or terminal damage. These could range from a standard circular saw to a custom-made cutting blade.

Series 1 champion Roadblock was armed with a circular saw as its secondary weapon, while Pussycat became one of the most successful machines in the show's run by making use of a cutting disc.

As one of the most common weapon types in the earliest series, there is no true pioneer for the weapon - House Robots Dead Metal and Sergeant Bash all used circular saws in Series 1 (with Dead Metal retaining this weapon type for the show's run), while the competitors armed with cutting discs included Roadblock, Scrapper, Plunderbird 1, Uglybot and more. Of these, Roadblock and the House Robots were the first to appear on television.

Definition[edit | edit source]

Pussycat's blades

A cutting disc (also referred to as a cutting blade) is a generally small, thin disc weapon designed to spin and cut into other robots, or grind at their surface. Typical off-the-shelf circular saws and grinding discs meet this definition (such as the weaponry of Roadblock), alongside custom-made cutting discs optimised for greater damage output, like the disc of Pussycat.

Over the course of the show's run, typical circular saws saw less frequent use, with many off-the-shelf discs shearing upon impact like the often-broken rear saw of Sergeant Bash, or Pussycat's original blade in Series 3. The custom-designed cutting disc saw more use throughout the later periods of the show's original run, but both weapon types proved very sparse in the reboot, with modern armour often totally resisting the effect of cutting discs.

Most cutting discs were small in size, although some competitors used larger-diameter discs throughout both of the show's runs. These discs, such as those equipped on the original version of Ming and the Series 8 version of The General, were closer to horizontal or vertical spinners in size, but featured more teeth or pointed edges along their circumference than a typical flywheel and retained the low thickness of a cutting disc.

Cutting weapons could easily be mounted on a moveable arm, enabling them to be brought down from overhead to improve the weapon's effectiveness or allow for a potential synergy with other weapons, such as Dead Metal clamping competitors in its claws before moving its circular saw directly into the trapped robot. Competitors such as Tentoumushi and Haardvark would use similar moving discs, with or without secondary weapons.

The primary purpose of cutting discs is to cut, shred and slice through other robots, unlike heavier and thicker spinners which aim to gouge, tear and concuss.

Advantages and Disadvantages[edit | edit source]

Pussycat's blade enabled it to cause significant damage throughout its Series 4 run, notably to Razer's armour and wheels in its Heat Final

The weight and small size of King B Powerworks' cutting disc allowed its team to equip the disc without compromising on the robot's lifting forks or drive system

  • As with other spinning weapons, cutting discs proved effective in causing damage to not only most kinds of armour - particularly in earlier series - but also wheels, wheelguards or other exposed components. Pussycat's Series 4 run best demonstrated this - not only was it able to cause extensive damage to the armour of Robochicken, Thermidor 2, Dominator 2 and Chaos 2 at various points during this series, but also sever Reptirron's fuel lines and damage the wheels/wheelguards of Razer and Hypno-Disc respectively.
  • Cutting discs could be easily integrated into an invertible design, as Pussycat, 3 Stegs 2 Heaven and the Series 3-5 and 7 versions of King Buxton demonstrated.
  • Compared to heavier spinning weapons, cutting discs are generally less affected by recoil, making them potentially more reliable at operating for full matches.
  • The lightweight nature of a cutting disc meant that any spare weight left over for the wielding robot could be used to incorporate additional weapons (e.g. a second cutting disc), tougher armour or more powerful drive systems. The cutting discs formerly used by King Buxton, for example, were added in such a way that they increased the robot's damage potential without compromising on the robot's armour, motors or primary lifting weapon.
  • Off-the-shelf circular saws and angle grinders provided a very inexpensive way to weaponise a robot in the earlier series of the show.


Pussycat's cutting blade could only cause superficial damage to M2 in Series 7, resulting in it losing the Judges' decision

Shredder's cutting disc is overpowered by S3's vertical spinner

  • Especially in later series, cutting discs very often struggled to damage tough armour, which put robots with them at a significant disadvantage on Judges' decisions. Pussycat's loss against M2 in Series 7 demonstrates this, as its blade could only cause superficial scratches to M2's armour at best. In the reboot era where HARDOX armour was commonplace and almost completely resistant to cutting discs, only a limited number of competitors implemented cutting discs into their design, and only in Series 8.
  • Many cutting discs require sustained contact to output their full damage potential, contact which is often hard to maintain in the arena. When faced with tough armour, cutting discs may also stop or jam upon contact if they cannot cut through.
    • Wild Thing demonstrated a rare example where a cutting disc could not break free from its opponent after cutting through its armour, becoming locked together with Vader after its cutting disc could not break free
  • Cutting discs are particularly prone to entanglement devices (intended or otherwise) and other exposed components, such as when 3 Stegs 2 Heaven's disc was entangled by the cables of Eleven, or when Pussycat's blade was totally stopped by the fur of Diotoir.
  • Being lightweight in nature, cutting discs are generally overpowered by heavier spinners, such as when S3 ripped an entire cutting disc from Shredder with a single blow, or when Fluffy ripped away the blade of Pussycat.
