Example clippable multi-tone whistles, as well as systems and methods for manufacturing the same are described. An example clippable multi-tone whistle may comprise: a clip attached to a whistle body. The whistle body comprises a flat surface under the clip; a first opening configured to allow air flow to come into the whistle body; and on the flat surface a second opening configured to allow air flow to come out of the whistle body. The second opening is at least partially blocked by the clip, which controls direction of one or more air flows coming out of the second opening. The whistle part is configured to generate a plurality of different sound tones in accordance with user finger movements around the clip and the second opening. The whistle may further comprise a glass breaker, a length scale, and a bolt action switch, which may function as a fire starter.

The present disclosure provides a fire starter that does not require oxygen from the air to ignite or maintain a flame and makes it easy to ignite using one or no fingers, such as teeth. A fire starter includes a burnable casing forming a sealed chamber. A first burnable mixture and a second burnable mixture are separately disposed in the sealed chamber. The first burnable mixture can form a flame without oxygen from the air. An igniter is disposed in the sealed chamber adjacent to the first burnable mixture and configured to generate a first thermal event to ignite the first burnable mixture without oxygen from the air. The first burnable mixture combusts during the first thermal event and triggers a second thermal event to ignite the second burnable mixture. An actuator is configured to activate the igniter to generate the first thermal event without using more than one finger.

In one embodiment, a fire starter comprises a main housing having a cavity therein. A striker is mounted on an end of the main housing and positioned to extend over at least a part of the opening of the cavity. A spark producing rod is slideably and rotatably disposed in the cavity of the main housing. A biasing element is mounted around the spark producing rod to urge a first end of the spark producing rod into contact with the striker. A torque mechanism is attached near a second end of the spark producing rod to cause rotation of spark producing rod, the second end of the spark producing rod being an end opposite the first end of the spark producing rod.

The device disclosed herein is a handheld survival tool that incorporates a storage tube and a firestarting device into one ergonomic unit. Tinder and small survival items are stored within the device while a ferrocerium rod and scraper are stored externally. The replaceable scraper is fastened to one of the storage tube caps which allows the storage tube to be used as a handle for holding the scraper which greatly increases directional control while generating sparks. The ferrocerium rod is tethered to the opposite storage tube cap and secured within a sheath which prevents loss of the ferrocerium and provides a larger mechanism for holding the ferrocerium rod during spark generation. This device greatly improves upon the use, reliability, and function of prior fire-starting devices.
