The Idea of the Self-Defense Knife
A self-defense knife can protect yourself from anyone who tries to attack you. You would use the knife to threaten a person who is trying to cause harm. The knife may work well in any defensive maneuver to stop a person from carrying out actions.
A knife is a more useful option than a firearm. It’s easier to conceal a knife, plus there aren’t many restrictions over where you can carry a knife. It is also easy for a person to misuse a firearm and potentially harm someone by accident.
What Else Can You Do With Your Knife?
You can use a self-defense knife for purposes other than protection. Among the things you can do include:
- Cut through ropes, wood, and other items
- Prepare kindling for a fire
- Break glass; this would work with the butt end of the knife handle
- Saw through anything heavy; this is applicable if there are serrations on the blade
What To Find In Your Self-Defense Knife
You will have to look at how well the physical build on the knife works. Some knives are retractable and have blades that can flip back in when not in use. Others have fixed blades that use sheath coverings.
You’ll need a knife that is small enough to carry with you, but also one that isn’t hard to store. Fixed knives have to go in a sheath, but that unit should be easy to secure to your body when you travel. A folding knife can fit in your pocket, but you should see that it has a lock that will not open.
Look at how you can carry a self-defense knife. A handle must feature a body that lets you keep a firm grip. Some handles feature grooves for your fingers. Others feature rugged surfaces that keep the knife in your hand.
Some knife handles come with solid wood bodies, but some plastic polymers may also work. Rubber can also appear in some cases.
You should see that your knife is easy to hide. You don’t want your knife to be overly visible to where an attacker could notice it and possibly try to disarm you.
You should look for a secure place where you can hide the knife without risking harm. Be sure that your knife is slim or small enough to keep it from being visible.
The general functionality of the knife is also essential to note. The functionality refers to how well you can take out the knife and use it.
The knife has to be easy to use as soon as you take it out. You should flip the knife out and expose its blade well enough. It should also be easy to use with either hand.
Take a note of the blade and how well it works. A few things should be noted in your blade:
Most self-defense knives are made with steel. You might find stainless or carbon steel in most cases. Carbon steel has a lightweight body, but stainless steel does not corrode over time.
2. Blade Length
The blade should be long enough to where you have enough of a reach when on the attack. The blade should be about half the overall length of the knife when open.
3. Sharp Points
The sharp points on your blade can cover one or both sides. The points should provide enough room to penetrate items.
Some knives come with serrated blades. A serrated body features a few teeth that can work as a saw.
5. Blade Shape
The shape of your blade can also influence how well it works. Most self-defense knives come with a drop, spear, or clip point. The drop point features a curve at the end that goes up and is useful as an all-purpose knife. A spear point has a symmetrical design, with the two sides moving inward to the same central part. A clip point has a slanted point that moves up to a sharp spot at the top.
Your knife should be a few ounces in weight. Don’t take in anything all that heavy that might bog you down while walking. A lighter knife is also easier to wield.
Additional Points For Your Knife
There are a few other things to see when looking for a self-defense knife:
- Be sure to sharpen the knife on occasion. You can use a traditional sharpening stone.
- Keep the blade clean for the best results. Only use dish soap and warm water when cleaning it off. You might need to use baking soda if the body experiences any rust.
- Don’t store your knife anywhere where it might bang around, especially if you’re carrying it on a belt or other feature. Any excess movement could cause the blade to chip or break apart.
A self-defense knife ensures you stay protected no matter what the situation might be. You have to look at a knife that fits your hand well and won’t be hard to use. A helpful knife can be easy to hold and use, not to mention it won’t be hard to wield. You have to see that your blade has a good enough of size and that you won’t have any hard times holding it. You must also see that it has enough functions and features to enhance how well this works.
You have the option to go with a fixed or folding knife. But no matter what you use, you will require something with the best body around while being convenient for your use.
The best choice for a self-defense knife for your use is the Smith and Wesson SWHRT9B 9in High Carbon Knife. The knife has a better body that features a sturdy blade and will work in moments for most cutting needs. The rubber handle adds a good body that keeps the knife in your hand.
