Best Front Flipper Knives

Front flipper knives have been gaining a lot of steam in the knife community since the introduction in 2017 by Kizer Feist. Boker, Real steel, and many other manufacturers jumped into the ship and released multiple models.

Front flippers work similarly to other flippers, but the deploying mechanism is comparatively simple. To deploy the blade, you need a sweep of the thumb instead of using a finger.

The front flip mechanism invention is attributed to a South African knifemaker named Fanie Le Grange. They call the mechanism’ lip opener’.

The material of the blade

The first thing you will want to keep your eye on is the material of the steel. The best and most common option is stainless steel, and we highly recommend it. This blade won’t rust; it is immune to stains and relatively easy to sharpen and maintain.

Carbon steel is a bit different. It is stronger, looks better (for some users), but it makes a knife more expensive, and sharpening is more complicated and time-consuming. You will need a particular machine or a lot of time to keep the blade sharp.

The material of the handle

As you would expect, a flipper knife has a handle, which represents 50% of the entire unit. It is essential to add that the handle must be well-made and must be able to withstand a lot of stress.

The inner elements must be made from steel, as well. It is mandatory to ensure the blade remains away from your hand. The exterior can be made from wood, aluminum, or fiberglass. Always look for reinforced fiberglass or aluminum.

Size of a blade

A blade can be anywhere between 2 and 6 inches in length. We prefer smaller sizes because they make a knife more compact and more usable in different situations. At the same time, these knives are safer to use but very convenient. Be free to choose any length you like.

Safety lock

If you are getting an automatic or assisted model, you will need a safety lock. This is an additional mechanism that will prevent the blade from activation. Usually, it is a lever-based system that locks the blade when unfolded.

If you are a beginner and this is your first “blade,” we advise you to get a unit with a safety lock. It is added safety you can use when needed and doesn’t ad cost to the knife.


One of the main goals when choosing a flipper knife is to keep the weight as low as possible. Users like small and practical knives that are lightweight and easy to carry. We can see that the weight starts at 3 ounces and can reach 10 ounces. Between 3 and 6 ounces are a sweet spot and the best choice.

Additional features

Additional features refer to a glass breaker, bottle opener, or belt cutter. It is unlikely to find a knife of this type that has all the other features we mentioned. The chances are high that you will find a unit that has at least one or maybe two of these features.

They are nice to have, and they make a knife more usable and more effective when you need it. You will never know that you need a glass breaker or belt cutter until it is too late. We recommend you to get a unit with one of these two features.

Belt clip

You can get a knife with a belt clip or without. Models without having a slimmer and more desirable design and look better. However, they are more complicated to transport and carry. You must place it in your pocket.

The flipper knives with belt clips are extremely easy to carry with you at all times. If you carry the knife every single day, we recommend you to get a unit with this addition. You can remove it if you don’t need it.


The budget is the most important part. That’s why in the list of top knives we covered, we have included best flipper knives under 50 USD and best flipper knives under 100 USD



One of the best flipper knives you can possibly find today and the one we liked the most is Zero Tolerance 0562CF Hinderer Slicer Folding Knife. Thanks to the titanium handle, strong blade, and adjustable clip, it gets 10 out of 10. An impressive score if you ask us. The knife is stunning and will last for decades without any issues.
