OTF knives are widely available these days with many manufacturers designing OTF knives with different blade lengths, handles, and blade types. There isn’t a manual for choosing the best OTF knife because all individuals require different things from their knives.
Some will buy an OTF knife for camping and hunting purposes whereas others might want to own an OTF knife for self-defence or as a backup knife to have in your vehicle dashboard compartments. However, most professional hunters and knife collectors recommend choosing an OTF knife with at least 3.5-inch blade.
Moreover, think carefully about the type of blade you would want to purchase as different blade types will have different task performance. For instance, straight blades are very easy to clean and sharpen as well as perform clean and precise cuts hence these blades are recommended for hunting and fishing.
On the other hand, fully serrated blades are great for tasks such as cutting ropes, cardboard or other semi-soft materials. Serrated blades often will stay sharper often for longer than half serrated or straight blades hence they can be great for someone not wanting to deal with sharpening their knives.

What other blades of OTF knives are available?
OTF knives are often made with Tanto blades that are known for their angular shape thanks to the two straight edges that are joined together at the top. Tanto blades are often preferred over other blades because they have proven to be much stronger especially at the tip.
Another good blade is the drop point blade that is mainly used for hunting of knives however, they have a much thicker blade than the Tanto.
How to select a good stainless steel knife?
Nowadays, there are many types of stainless steel made in different countries and varying in their durability and strength. Often, the stainless steel used determines the quality of the knife as well as how long it will serve its user.
Most Asian stainless steel blades such as 420, 440A and 7CR13MOV are coated to be rust resistant however they are much thinner than other counterparts hence they require more frequent sharpening. American stainless steel blades are often made to be stronger and contain a much higher percentage of alloy and chrome.
They tend to be sharper and have a tendency to better hold the edge hence they need less maintenance as well as sharpening. Some examples of American made stainless steel blades are AUS6, 440C, and AUS8. Furthermore, Japanese stainless steel blades are the most expensive ones because they are made with a high chromium level.
Moreover, these blades are also often coated with another layer, for example, with vanadium for added strength and better edge maintenance. Vanadium is often used for better rust and corrosion resistance as well. Japanese stainless steel blades are marked with CPM154, VG-10 or S30V and tend to be sold with sheaths or in a box so as to further protect the blade.

This type of care routine will prevent the blade from corroding or rusting and thus rendering the knife unusable. Lastly, try to store the knife in a sheath or a box so that it doesn’t get scratched or scuffed plus storing the knife in a safe place will prevent you from accidentally hurting yourself.
