How To Choose The Best OTF Knife?

How To Choose The Best OTF Knife?

Buying an OTF knife for yourself can be a tough choice. OTF knives are available in a wide price range and are equipped with different features.

If you’re planning to keep an OTF knife for self-defense purpose, you have to be sure that you choose the best one. You’ll want the OTF knife to open smoothly and swiftly which is your only chance at defending yourself in emergency situations.

Below are the factors that you should consider when choosing an OTF knife for your self-defense.

Blade Sizes

The size of the blade you prefer is completely up to you. Usually, OTF knives with larger blades are Meany for heavy-duty tasks. For self-defense, OTF knives with smaller blade size will work perfectly well.

Edge Type

The blade of the OTF knife could be straight, fully-serrated or partially-serrated. Depending on the nature of your work and the level of dense you want, the choice of the blade will vary. For general use, a straight-edged blade does the job well.

Blade Shape

The shape of the blade could be any of the following:

  • Tanto
  • Clip point
  • Drop point
  • Spear point

Each shape has a different penetrating power. Your choice should depend on your requirements.

Just because Tanto appears to be the sharpest doesn’t mean you need to purchase it. If you think a simple drop point will serve the purpose well, that’s what you should spend your money on.

Steel Property

The steel quality varies from good to best. If you want to keep a OTF knife just for a sense of security, a normal quality steel would do.

However, if you’re a hiker or hunter, you’ll need sharper and stronger blade that only the best-quality steel can deliver.
