Keychain knives: are they as functional as they are aesthetic?

When talking about keychain knives, those unfamiliar with the cutlery field tend to think they are neck knives. Although both are characterized by a blade measuring no more than 4.5 cm, they do not belong to the same category. Keychain knives are more compact and are available in different versions. And due to their miniaturized design, they are most often used as decorative accessories on a keyring or bag. The question thus is: do these knives have a functional side? Let's decode...

What is a keychain knife?

If a neck knife, as its name indicates, is worn around the neck, the keychain knife suggests that it is a decorative accessory. Admittedly, most of the time, enthusiasts use it only to give an aggressive look to their backpack or pocket. But its reduced size and ergonomic design in no way allude to its great practicality.

Light, maneuverable and elegant at the same time, a keychain knife is a tool that can prove to be an excellent alternative to survival knives. Its use also remains within the legal framework. Equipped with a sharpened blade running elegantly along the handle, a keychain knife can be used to trim a branch, cut a rope or fillet a fish. Design-wise, it can come in different shapes to the delight of collectors. While some look deceptively like miniature pocket knives, others are similar to miniaturized survival knives.

Keychain knives: true self-defense weapons

As unlikely as it may seem, keychain knives were indeed designed primarily to serve as self-defense weapons. Among the very first models that appeared on the market are: the Eylife knife. It was developed in 1960 to meet a single use: discreet self-defense. Its stainless steel blade concealed inside a black anodized aluminum handle was able to pierce any material. Even today, the Eylife keychain knife circulates widely on the market. But it has been largely surpassed by the Micron miniaturized folding knife from SOG, the SayHia pocket knife as well as the Promithi multifunction from Morphing.

Keychain knives: fixed blade or folding blade?

Fixed blade keychain knives, such as the n°02 model with a stainless steel handle from the Opinel brand, are extremely stylish knives. The aggressive, dissuasive and practical side is quickly noticeable. If you want to impress your friends, these knives are to be preferred. They will not fail to add some pep to your style.

However, if you plan to use a keychain knife for functional purposes, prefer folding blade models. Admittedly, they are more discreet. But in terms of performance, they are the most sought after. They are also more secure compared to fixed blade models. Thus, whether you want to carry your knife in your pocket or on your belt loop, it will not risk injuring you. The blade will only open when you have activated the unlocking system.

How to maintain a keychain knife?

Whether it stays in your pocket or is attached to your carrying bag, your knife will never be safe from dust and external aggressions. A reason that explains why regular and meticulous maintenance is necessary. To prevent the handle from losing its shine, remember to wipe it with a soft damp cloth after your outings. As for the blade, remember to sharpen it once or twice every 6 months. It will thus retain all its practicality.
