Best Budget OTF Knife: Reviews of Top Models

Last Updated: by Aiden Williams

OTF knives also known as telescopic or sliding knives are your cooler, quicker, and more efficient versions of pocket knives, a badass blade in every right. For clarity, OTF is short for “out-the-front,” which aptly describes the way its blade extends out to the front in an open position when you engage its button or slider knob.

Guide To Finding The Best Budget OTF Knife

For you to understand enough to make a great buying decision, you must first understand the unique factors to watch out for when choosing an OTF knife.

Another reason for reading this guide before you make your choice is the fact that you don’t want to be bamboozled by a vendor’s sweet talk that would make you want to either buy what you do not need or more than you need.

Types Of OTF Knives

Manual OTF Knives

These are opened and closed by pressing a sliding switch downwards/upwards

Automatic OTF Knives

These are predictably savvier, and further divided into two sub-categories: single and double action. Both automatic OTF knife types can be opened by pressing a button and then it pops forward, but the difference is in the closing action.

For single action OTF knives, you have to close manually by pulling the slider back or whatever means the brand is designed.

The double-action blades on the other hand open and close with a single button press, assisted by a spring technology that makes it pop forward and back.

By the way, if you are ever wondering whether to choose between a single or double action OTF knife, ponder on the fact that while double action knives are savvier and with “cooler” functions, the single action knife is less fancy but much more reliable in the long term.

The major distinction between an automatic and manual OTF knife is that the manual OTF knife operates with a slider while its automatic counterpart uses a button to pop open and close.

Things To Consider If You Want To Carry A Knife

Now that you know both types, picture this: You need a great budget OTF knife for your hunting and camping adventures or to protect yourself or because your profession requires it, where do you go first?

No, not the local knife store. We have more practical answers on the issues listed below:

Legality

It is important to find out and understand the laws governing the possession of OTF knives in your area because as fun and effective as our pointy little friends are, they are also quite dangerous.

Thus, you might want to check out the state-by-state blade laws in the United States on this page. If you live outside the United States, contact your local attorney and get educated on the legal paperwork you require (or not) before you go shopping for an OTF knife.

Purpose

Yes, you must always find the why. Is this something you want to do for the “art?” collecting some shiny steel toys and showcasing to your friends at dinnertime?

Is it something you keep in your pocket for lonely walks and drives at night? Or is it for game hunting? You can only understand the type of blade you need if you know why you are buying it.

Size

Is it really a pocket knife if it can’t fit in your pocket? Smaller sized and lightweight knives are usually the go-to weapon of choice for everyday carrying. On the other hand, bulkier and longer models are great for outdoor adventures.

Blade Type

There is a vast selection of blade types out there but don’t allow yourself to get confused. For their superior toughness and cutting range, we recommend 8cR13MoV Blades.

However, you shouldn’t buy them if you are not one to maintain your tools consistently, because these blades require regular sharpening and lubricating.

Likewise, CPM S30V Blades may not need as much cleaning, is not as tough, but makes incredibly precise cuts on most materials.

Essentially, you must always ask the vendor what type of steel the blade is made in before you make a purchase, and if you don’t know the blade, don’t give up on it just yet. Look it up online, you might be in for a good surprise.

Edge

The importance of your blade’s edge cannot be overemphasized. The major edge types are Straight blades for clean and sharp cuts thus perfect for hunting, fully serrated blades for ripping through the toughest materials with little need for precision, and partially serrated blades, a mix of straight and fully serrated, perfect for general use.

Handle Type

Grip is essential, so in this case, your first choice should be a rubberized handle or alternatively, an aluminum handle. An aluminum handle with a rubber inlay makes for a perfect blade.

Maintaining Your OTF Knife For Longer Life

Learn how to prolong knife life with the following measures:

  • Keep your blade free of dust and moisture to reduce the risk of corrosion or rust. Should it ever get wet, dry immediately with a clean micro-fiber towel and keep in a dry place
  • Clean your knife after every use and clean thoroughly. Before you clean, always disassemble the parts and ensure that every bit is properly cleaned. This will also keep the internal mechanisms dirt-free and in good working condition. You can use a screwdriver to dislodge the knife. Also, pay attention to the smaller details on the knife that your cloth cannot reach by using a Q-tip to clean those tiny areas
  • Using light lubricants in small quantities, lubricate the knife after cleaning with emphasis on the internal mechanisms. As an extra measure against oxidation or corrosion, apply a thin layer of lubricant on the blade of the knife then reassemble your knife back to its original state
  • Do not forget that a knife is only as good as its razor-sharp edge, and keeping your OTF knife sharp is one solid way to extend its life. While whetstones are generally considered a great tool for sharpening knives, note that not every sharpening tool is suited for your knife. That said, always research on the best kind of tool for sharpening your OTF knife before you make a purchase. Edge maintenance and retention is crucial to ensuring that your blade does not dull easily
  • If you won’t be using your knife for a long time, discharge the blade and store both parts separately, as having a blade in its handle unattended for too long will lead to rust and corrosion
  • When you are not using a knife, sheathe it and put it away immediately. It is not a toy for idle play. Also, store in designated areas rather than random places where anyone can pick them up

Final Thoughts
