The blades are made of high-quality carbon steel and you do not need to sharpen them or prep them before use. They are ready to use right out of the packet.

Measuring over 4 inches in length, the JKN89 pocket jack for carving is compact and can fit your pocket or in the pouch of the bag, you are carrying. When all the blades are folded in, it fits in hand. 

This makes it perfect for the traveling woodworker. Unless they are opened up, you do not immediately see the blades. This is a good-looking handy knife. It also comes with a great-looking top-quality leather pouch.

Performance Review

One of the most immediate design flaws that you are most likely to face with this tool is that it is difficult to open the blades out when you need to use them. For a tool that is meant to be convenient and easy to use on the go, it is necessary to access the blades when you need to easily. 

The notch to pull out the blades is not easy to grab, and some end up having to use a pair of tweezers or another tool to open the blades up. This is undoubtedly a major inconvenience. 

However, this is the only negative thing we could find about this tool. Otherwise, its unique locking system makes for a tool with enhanced safety features. Technically speaking, the blades are made of high-carbon steel. The handle is made of stainless steel.

The blades are very sharp and ready to use right out of the packet. The straight knife is used to model surfaces and also create different textures. If you wanted to imprint a specific design on the wood, this knife would do the trick for you. 

The second blade is the gouge scorp which is right-angled and has a short turning radius, which will allow you to carve narrowly and deeply. The third blade, the v-scorp, has sharp corners that leave a clean separation between the two surfaces. The fourth blade is the detail knife, and this is what you will use to detail delicate parts or to remove wood from a convex surface.


Safety is key when you use any tools. We always tell children not to run with scissors, but this also applies to adults. When you use sharp tools, you must stay safe and protect yourself and others around you. 

One way of doing this is to make sure of this to check on the blades and make sure that they are safely used and stored when you are done. 

All the blades are razor-sharp, and you must handle them with caution. You must know how to lock the blades in place. Make sure to hear the click before you are satisfied that the blades are locked in place so that you can use them safely. 

When you use it, always ensure that the other blades you are not using are safely locked away. To tuck the blade not in use away, push a button on the side of the handle, and it easily folds back in. 

This will keep your fingers safe. Under UK/US laws, you can not sell the JKN89 pocket Carvin jack to people under 18. This is an essential precaution to ensure safety.

Who is this product ideal for?

When it comes to using blades of any sort, you must know what safety precautions to take and also be honest with yourself about your skill level. The JKN89 pocket carvin’ jack is a multi-purpose folding tool best suited for woodcarving enthusiasts and generally those who know their way around wood-carving. 

This is because the different blades have their uses, and they are very sharp. It is necessary to know how and when to use them.

Our Verdict

The fact that you have to pull out the blades using another tool is not great. It is inconvenient and negates the beauty of having a portable tool that you can use on the go. You want to make sure that you have an all-rounder tool and do not need rocket science to use. 

Other than that, this is a great knife to use when you are on the go. The blades are handy and sharp, and they do the job. When it is closed, it fits nicely in your pocket. The handle is also beautifully designed to fit in your hand and give you the grip that you need as you work. 

This tool is a must-have if you find yourself often on the road or away from your toolbox, needing to carve wood. This is usually the case if wood carving is a hobby of yours. You never know when you will get the inspiration for a new piece. 

Tools that are portable like this one are a great addition to your arsenal. It is almost like having an entire carving kit all in your pocket. We think it’s a good buy. Carve safely with a tool made for the job. Happy shopping! By the way, check out our Flexcut KN30 Hip knife Review.
