You can use an action to spill these tiny metal balls from their pouch and cover a level, square area that is 10 feet on each side. A creature moving across the covered area makes a DC 12 Dexterity saving throw or falls prone. A creature moving through the area at half speed doesn’t need to make the save.

A bell is a directly struck idiophone percussion instrument. Most bells have the shape of a hollow cup that when struck vibrates in a single strong strike tone, with its sides forming an efficient resonator.

A grappling hook or grapnel is a device that typically has multiple hooks (known as claws or flukes) attached to a rope or cable; it is thrown, dropped, sunk, projected, or fastened directly by hand to where at least one hook may catch and hold on to objects. Generally, grappling hooks are used to temporarily secure one end of a rope. They may also be used to dredge for submerged objects.

A hammer is a tool, most often a hand tool, consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. This can be, for example, to drive nails into wood, to shape metal (as with a forge), or to crush rock. Hammers are used for a wide range of driving, shaping, breaking and non-destructive striking applications. Traditional disciplines include carpentry and blacksmithing.

An hourglass (or sandglass, sand timer, or sand clock) is a device used to measure the passage of time. It comprises two glass bulbs connected vertically by a narrow neck that allows a regulated flow of a substance (historically sand) from the upper bulb to the lower one due to gravity.

A key is provided with the lock. Without the key, a DC 15 thieves’ tools check can pick this lock. At the Narrator’s discretion, there may be better locks available for higher prices.

This lens allows a closer look at small objects. When you use a magnifying glass to appraise or inspect an item that is Tiny or highly detailed, you gain an expertise die. A magnifying glass is also useful for starting fires. Lighting a fire with a magnifying glass requires light as bright as sunlight to focus, tinder to ignite, and 5 minutes of remaining stationary.

These metal restraints (AC 16, 20 hit points) can restrain a Small or Medium creature. You can restrain an unwilling creature which requires an action, and for the creature to be either restrained, or both grappled and prone. Escaping the manacles requires a DC 20 Dexterity check, and breaking them requires a DC 20 Strength check. Each set of manacles comes with one key. Without the key, a DC 15 thieves’ tools check can pick this lock.

Oil usually comes in a clay flask that holds 1 pint. As an action, you can splash the oil in this flask up to 20 feet, shattering it on impact. Make a ranged weapon attack against a target creature or object, treating the oil as an improvised weapon. On a hit, the target is covered in oil. If the target takes any fire damage before the oil dries (after 1 minute) it takes an additional 5 fire damage from the burning oil. You can also pour a flask of oil on the ground to cover a 5-foot-square level area.

This small clay pot contains about a pint of a single color of paint, enough to cover 50 square feet. Alternatively, as an action, you can splash the contents of this pot up to 20 feet, shattering it on impact. Make a ranged weapon attack against a creature within 20 feet, treating the paint pot as an improvised weapon. On a hit, the target is covered in bright paint. The paint can only be removed with at least 1 minute of vigorous scrubbing. While covered in paint, a creature has disadvantage on Stealth checks.

Thick, tightly-woven sheets of silk and thin rods are carefully set into this backpack (AC 9, 6 hit points). While wearing a parachute, when you are falling you can use your reaction to pull on the ripcord to deploy it. Your rate of descent slows to 30 feet per round, and by making a DC 15 Dexterity check on your turn you can move up 5 feet horizontally for every 5 feet fallen (up to a maximum horizontal distance equal to half your Speed).

A mixture of fragrant essential oils used to give the wearer an agreeable scent.

Individual Communication Devices (ICD) are very common in most societies. A typical device allows its user to communicate by video, audio, or through text, can connect to whatever society-wide network exists, and runs a selection of useful programs. A personal communicator is typically a small device controlled with hand gestures, but it may take the form of a heads-up device that combines a monocle or visor with an earpiece, a wristwatch, or even a badge worn as a pin on the lapel.

This tripod mounted device has an aperture to keep out light until a picture is ready to be recorded. A treated photochemical plate is slid into the camera and the aperture is opened for about a minute, or longer in dimmer conditions. Exposure to light in the presence of a certain gas causes the image to set on the plate, and a quick saline rinse ensures the image will not develop further if exposed to more light. These photographs are popular among the lower classes, who cannot afford proper portrait paintings.

A pickaxe, pick-axe, or pick is a generally T-shaped hand tool used for prying. Its head is typically metal, attached perpendicularly to a longer handle, traditionally made of wood, occasionally metal.

A metal spike (usually steel) that is driven into a crack or seam in the climbing surface using a climbing hammer, and which acts as an anchor for protecting the climber from falling or to assist progress in aid climbing.

In addition to telling time, a pocket watch deters the attention of minor fey. Watches will occasionally stop, skip, or run backward in the presence of powerful fey creatures.

A 10-foot wooden pole used to probe depths or span gaps.

These devices are designed for scenarios where a larger viewable area and/or a bit more processing power than an ICD is desirable. They may be a folding device with a separate keyboard or other control panel and screen, or they may look like a giant ICD (this latter type is sometimes referred to as a datapad). In some worlds, they may also be worn on the arm, generating a user interface out of projected light that can be interacted with by multiple appendages at once.

You can use a portable ram to break down doors. When doing so, you gain a +4 bonus on the Strength check. When another creature helps you use the ram, you gain an expertise die (as well as advantage, as normal).

When you set a mine, you can link it to a remote detonator, allowing any creature holding the detonator to trigger the mine as an Interact action. 
Typically, a detonator’s range is limited to 1,000 feet, but a mine connected to a detonator via a computer network can be detonated from essentially any distance.

These devices interfere with the signals generated by wireless networks of various types. Signal jammers are usually found in the possession of militaries and clandestine organizations, but criminals, security services, and hackers employ them as well. The listed cost is for a small version that fits in a backpack or briefcase, but larger ones that require vehicles or even towers to employ also exist. The portable version covers roughly 4 city blocks, making it impossible to get a wireless network signal in or out of the area while it is active. Setting the jammer up takes a minute.

A musical instrument which produces sound when blown into.

Finely polished planks strapped to the boots of the wearer,skis allow for swift crosscountry and down-hill travel in snow. It takes 5 minutes to don or doff skis (though the ties can be cut as an action, the skis are then considered broken). In difficult terrain caused by heavy snow, you can take the Dash action as a bonus action across level ground or the Sprint action as a bonus action if going downhill. While wearing skis you have disadvantage on Dexterity saving throws unless you choose to throw yourself prone

This durable device provides tactical mobility without requiring use of the legs. While mounted on a wheelchair you are considered to be wearing the wheelchair as a piece of gear. The wheelchair is mechanically complex, and can ascend stairs and ramps slowly, or provide a boost of speed on the descent. You have a movement speed of 30 feet while mounted on a wheelchair and treat inclines and stairs as difficult terrain, but while moving down slopes, stairs, or other significant declines you may take the Dash action as a bonus action.

A sharpening stone used for knives and other cutting tools.

Dispensing with portability entirely, these larger-scale computers are used on desktops or ship’s terminals. They have a lot of processing power and are favored by those who need it like engineers, programmers, gamers, hackers, and those responsible for creating media such as video and music.
