A multi-purpose weapon comprising a handle, an axe blade, and a straight knife blade. The axe blade includes a chopping surface, and two curved surfaces, which, when sharpened, allow the weapon to be used in a similar manner to a kerambit. Thus, in a single weapon, the user can use the straight knife blade, the axe blade, and the one or two curved blades.

A martial arts training device includes one or more anatomically correct simulated body parts (ACSBPs), including at least one of: head, neck, one or more legs, one or more arms and torso, at least one of said simulated body parts including at least one resettable, breakable or hyperextensible simulated anatomical element, the element simulating human joints, ligaments, tendons or bones. In embodiments, each of the ACBSPs includes a covering of simulated human skin, and wherein following a break or hyperextension of the resettable element, the element may be reset to its undamaged position or resting status to engage the device repeatedly.

A punching bag kit includes a suspension line, a target having a fastening mechanism for suspending the target from the suspension line in a manner allowing the target to move along the suspension line, and a blocker positioned on the suspension line at a configurable distance from the target. The blocker is frictionally held in place on the suspension line at the configurable distance. Movement of the target along the suspension line is restricted upon the fastening mechanism of the target impacting the blocker. The blocker is physically larger than the fastening mechanism thus impeding travel of the fastening mechanism along the suspension line past the blocker. The blocker may have holes through which the suspension line passes, and a spring-loaded friction device may be mounted on the suspension line between two holes. The suspension line may travel around a user in plurality of segments suspending one or more targets.

A contact sports training device is disclosed in which a single individual may realistically practice two-person contact sports, self-defense, or martial arts techniques that include grappling, blocking, and deflection, which may include a flexible back plate and one or more arms attached thereto to realistically resist and flex when a force is applied by a trainee, allowing for the practice of techniques that teach how to strike through, deflect, or penetrate defenses in a more lifelike training scenario. The contact sports training device may also include simulated weapons, be mounted to a heavy bag, Bob, or other surface by straps or fasteners. Methods of training with a contact sports training device are also disclosed, including providing a responsive contact sports training device having simulated human arms extended forward in a defensive posture.

A wearable score-keeping device to reliably record successful strikes in games of mock swordplay is provided. In one embodiment, a player (111) wears a breastplate device (110) that houses a target module (114). Contacting the strike zone (116) of the target module (114) of the opposing player with a sword device (112) is each player's objective. When contact is made with the strike zone, an impact switch (216) relays that information to a circuit board (220), which is programmed according to game rules chosen by the players (111). The circuit board then instructs one or more signaling devices (118, 218) to alert the players (111) to any landed strikes and so keeps score.

Sports equipment comprising a handle and at least one stem made of soft and light material fixed and aligned to the handle. The weight of the handle is considerably greater than that of the stem.

A combat system is disclosed that includes a garment and a weapon. The garment includes a computing device and a plurality of sensors positioned across the garment. The sensors are operable to detect an impact thereto from the weapon. The impact is measured in terms of pressure and duration and used to calculate a resultant damage amount.

Systems, apparatuses and methods may obtain motion data, obtain audio data, and detect a collision between a handheld device and an object based on the motion data and the audio data. In one example, noise may be removed from the motion data and the audio data to obtain filtered collision data, wherein the object is classified based on the filtered collision data.

A martial arts training device includes one or more anatomically correct simulated body parts (ACSBPs), including at least one of: head, neck, one or more legs, one or more arms and torso, at least one of said simulated body parts including at least one resettable, breakable or hyperextensible simulated anatomical element, the element simulating human joints, ligaments, tendons or bones. In embodiments, each of the ACBSPs includes a covering of simulated human skin, and wherein following a break or hyperextension of the resettable element, the element may be reset to its undamaged position or resting status to engage the device repeatedly.

An exemplary martial arts training device comprises anatomically correct legs, arms, torso and head that can be used individually, or partly or fully assembled. A user interacts with the device, and receives both immediate feedback and a global analysis of his training session. Feedback can include whether proper forces and angles were applied to achieve an actual break or other desired fighting goal in an opponent, and can be measured by the actual breaking of various strike points on the device, or by alerting the user when an appropriate sensor is struck with the required strength. The device can include breakable joints, bones, as well as soft tissue targets preset to respond to a defined striking force or joint manipulation. The user can reset the damaged physical structure or response sensor to its original configuration and setting, making the device repeatedly reusable.
