In a world where knives gain more and more notoriety in self-defense, various brands have come up with clever ways to disguise such weapons into ordinary items and vice versa. It is no longer a surprise that you can safely keep pocket knives in your pocket or purse without risking to injure yourself, but these days, they can embrace all kinds of shapes and designs. Surprisingly enough, you can also find knives disguised into lipsticks or even combs.

On the other hand, ordinary items like combs can also be disguised into knives. Most of them are designed like pocket knives. You open the knife, but instead of having a sharp blade for self-defense, you get a comb – usually metallic. Choosing the best comb knife can be a little challenging though because they are not extremely popular.

About comb knives

Generic New 1Pc Black Metal Practice Butterfly Comb Style Knife Trainer ToolA comb knife is mostly a comb, rather than a knife. It is disguised as a knife though – usually a folding knife or a pocket one. You can also get a butterfly comb knife, which looks like a butterfly knife. The difference is pretty obvious though. No matter what style you get, there will be no blades involved. While it looks like a knife if closed, a comb blade comes out when opened. These knives are designed to make good accessories when you are on the go.

Whether you need to refresh yourself during a party or you have a beautiful beard that needs some combing now and then, this type of knife will certainly help in the process. It is not large and wide and it can be easily hidden. It is convenient, compact, and ideal for numerous occasions when your fingers represent your only alternative. Furthermore, these knives are more qualitative than classic plastic knives – some of them are metallic and likely to last for ages.

Just like classic combs, comb knives come in different sizes. Plus, while they are more suitable for on the go situations, you can also see barbers or hairstylists use them due to their convenience. They keep them clipped by their belts or hidden in their pockets. Choosing the best comb knife yourself will give you access to a quick option to freshen up. Plus, the knife design (be it a pocket knife or a butterfly knife) will make it look sophisticated.
