Survivalists must pack cutting tools, firemaking devices, and multifunction compass. These items should be lightweight, compact, and sturdy enough to do heavy-duty work. They should also have a back-up tool, such as a folding survival knife. Multi-tools can include both cutting tools and firemaking devices. Fire is essential for purifying water and maintaining body temperature. Different kinds of firemaking tools are practically weightless, and can be found in most survival kits.

Cargo tape

One of the most important items in any survival kit is cargo tape, or duct tape. Its versatility is unmatched, and it can be used for a number of different purposes, from a tourniquet to patching a hole in a garment. The tape's adhesive is also flammable, which means it can help start a fire. Cargo tape should always be two inches wide, or larger.

Multifunction compass

A multifunction compass is a great tool to have on hand for many different outdoor activities. These devices feature a high impact plastic case, a contoured easy grip bezel, 2-degree graduations, and a declination scale. These tools can even be used while kayaking. In addition, they can help you navigate your way to your destination. In addition to being useful for outdoor activities, multifunction compasses can also help you navigate a city.

Combustion device

If you have a fireplace or other similar combustion device at home, there are 10 C's you should consider before purchasing it. These 10 C's are related to combustion quality and safety. When it comes to combustion, the first C is Combustion Quality. Whether the CO production is high or low depends on how the combustion device is designed. Insufficient primary air opening and combustion not following the design are two reasons why the CO production is high. It's also important to ensure that the secondary air is sufficient for complete combustion. No reliable visual inspection or measurement of CO emissions will reveal if your combustion device is functioning properly.

Cutting tool

A cutting tool is one of the 10 c''s of metalworking. A cutting tool can be a single-edge tool or a multi-edged tool. The former is used in the cutting process, while the latter is used to shape the workpiece. Single-edged tools are crafted from hardened metal alloys, and their shapes differ based on the tool used and its alloy composition.

Compass

A compass is a simple tool that can be used by anyone, regardless of skill level or geographic location. Make sure your compass is multifunctional by purchasing one with a mirror, ruler, and magnifying glass. If you must use candle light, invest in a headlamp. This will free up your hands while you're working. If you're camping in a dark location, invest in a headlamp with batteries.

Cordage

Although cordage will not affect Core Temperature directly, it can be a very useful item for a number of purposes. For example, you can use cordage to repair gear, construct shelters, and make bow drill fire. Cordage can be made of many materials and takes some time to prepare. The best cordage to use for the 10 C's is tarred braided nylon, which is waterproof, can be divided into strands, and is smoother than paracord. It will also hold knots indefinitely.
