Double and Single Finger Knucks from Afrankart

I recently came across these Single Finger Knucks (SFK) and Double Finger Knucks (DFK) that are made by Afrankart. At first, I was struck with how unique they look – they have a very distinctive style. However, it is also very apparent that these knuckles are very functional.

Double Finger Knucks

Single Finger Knucks

The knuckles were obviously made for striking. They are .625″ thick which is quite thick compared to many knuckles on the market. Thicker knuckles transmit impact over a larger area of your hand which means they hurt less and have less potential to injure the user. Great care has been taken to round all the edges to increase comfort and there appears to be plenty of material behind the finger hole to support the finger during a strike. The striking surface of these knucks is tapered so they concentrate the force of the strike.

The DFKs are available with 2 different striking surface configurations: pointed and rounded. The pointed version looks brutal. The SFK is available with the rounded striking surface only.

These can be made from several different materials and finishes. Aluminum and brass are available with a machine finish or bead blasted. G-10 is available as a more discreet, non-metallic option. Andy tells me that these will be available in Carbon Fiber soon.

The finger holes measure .950″ which should comfortably fit up to a size 13 ring finger. That should be large enough for most users.

If you are interested in purchasing a set of these reasonably priced knucks, contact Afrakart via email at afrankart@woh.rr.com.

Review: Paul’s Sap from Andy’s Leather

I recently reviewed a great classic leather sap from Andy’s Leather. That sap was similar to most saps in that it consisted of a weighted leather pouch on the end of a flexible handle. Saps have been made this way for years. However, the sap that I will be reviewing today is a departure from tradition.

The Same but Different

The “Paul’s Sap” model from Andy’s Leather looks like any other sap at first glance. In fact, no amount of visual inspection would lead you to believe that the Paul’s Sap is anything other than a traditional sap. That all changes when you pick it up. Once the Paul’s Sap is in hand you immediately notice what sets it apart – a thick steel rod inside the handle. This steel rod makes the Paul’s Sap completely inflexible at the handle. This is no ordinary sap. It is a blurring of the line between sap and straight baton, and it is devastating in trained hands.


Andy, of Andy’s Leather, is a police officer and also a baton instructor. Paul’s Sap is the result of Andy’s experience as a baton instructor with input from tactical trainer, Paul Gomez. The goal was to create a traditional looking sap that could be seamlessly worked into someone’s existing straight baton techniques. The rigid steel rod in the Paul’s Sap handle allows it to work with the same strikes and techniques that can be used with a straight baton. This reduces the amount of impact weapon specific training that is necessary because the same training translates from stick to sap.


The steel rod is hammered into the ball of lead shot that is in the weighted end of the Paul’s Sap. Then it is stitched inside the leather exterior of the sap. The stitching is evenly spaced, straight, and clean. Andy stitches these saps while they are still wet with the leather cement so that the cement is drawn through the seams with the thread which he says creates a stronger bond between the layers of the leather.

The Paul’s Sap model that I have to review is actually an example of a new option that Andy will be offering his customers. It is made from durable leather in a saddle tan color that, while durable, has a much more utilitarian appearance than Andy’s typical richly dyed bridle leather saps. This will serve as a lower cost option for those who need a durable, hand-crafted tool but have to work within a smaller budget.

In use

The Paul’s Sap is really a joy to work with. It allows you to deliver a strike no matter how it is indexed in your hand because the stiffening effect of the steel rod makes every surface a striking surface. When it is dark enough that you can’t see your hand in front of your face, it is comforting to know that you have a tool that doesn’t require the perfect grip to operate.

All of the typical sap techniques work with the Paul’s Sap however it can also be used deliver strikes and jabs. Hammer fist strikes are particularly painful and easy to deliver with the Paul’s Sap. Simple thrusts are one of the easiest techniques you can use with the Paul’s Sap. A sharp thrust that comes straight out from the user’s body and connects with the ribs, collar bone, or chin is very effective and difficult to block. A thrust with normal sap would cause the sap to fold and flex which would make the thrust less effective. The Paul’s Sap is rigid enough to stand up to these techniques.

The lanyard strap on this particular sample runs from the top of the sap to the bottom. This type of lanyard provides retention without having to take the time to wrap it around the user’s wrist. The user simply grabs the sap through the lanyard. The lanyard passes over the back of the hand, providing a measure of retention. It even provides some retention in the event that you grab the sap the wrong way with the strap going over your fingers.


The Paul’s Sap from Andy’s Leather is definitely unique. The steel shank in the handle makes it feel like an entirely different tool but very familiar at the same time. Those who have trained with a sap, a straight baton, or both, will feel right at home. The ability to deliver strikes and jabs regardless of how the Paul’s Sap is being held make this a potent and more fool-proof self-defense tool. Whether you choose a utilitarian finish like this sample or a Paul’s Sap with all the richest options, you will be investing in a tool that you will be able to pass on to your children.

Andy’s Leather is a full custom shop so you can contact him at www.Shotist.com or www.AndysLeather.com in order to discuss all the options for your very own Paul’s Sap.

As with any other weapon, you should seek professional training in order to use the weapon safely and efficiently. I always recommend George Matheis of Modern Combative Systems for impact weapon training.

Review: NukoTools Punch Ring

The NukoTools Punch Ring actually looks relatively innocuous.

The NukoTools motto is “Leave an Impression” and the Punch Ring certainly lives up to that motto.

The Punch Ring is a discreet, last-chance impact tool that is designed to make punching more efficient and devastating. To use it, you simply place your index or middle finger through the large hole and make a fist. It features a sharp chisel edge on the front that comes to a slightly rounded point. This sharp edge extends forward of the user’s fist when the tool is gripped properly. This edge will cause deep bruising and lacerations when it contacts flesh. It serves to concentrate the force of the punch over a much smaller area which causes more damage. This edge also makes the Punch Ring useful for raking the face rather than just punching.

The back of the Punch Ring is wide (about 1.25″) to spread the force of the impact over a larger area of the user’s palm. The Punch Ring is thinner (.214″ thick) than some knuckle type impact tools but that may be a price you pay for such a compact and discreet tool. This rear edge can also be used when to inflict pain when trapping , squeezing, or raking your opponent’s arms, face, and ears.

One side of the tool is left smooth which helps you to index the tool, even when you can't see it.

The NukoTools logo is just as clever as the tool.

To fit with its discreet mission, the Punch Ring is made from G10. G10 is a laminate material that is extremely durable and non-metallic. One of the sides of the Punch Ring is textured which can help you index the Punch Ring without actually being able to see it if you are carrying it in your pocket. Every corner of the tool that will come in contact with the user’s hand has been carefully beveled to reduce discomfort. The Punch Ring also has a small hole that allows you to attach it to your keys or add a lanyard.

I used the punch ring on various materials that I could get my hands on. The edge is sharp enough that it can be used to cut paper and packing tape. It is surprisingly sharp. It sinks easily and deeply into several layers of corrugated card board. Dry wall gives way readily. Even soft wood is no match for the punch ring. The thin material that the Punch Ring does cause some discomfort to the palm when really getting behind a punch but it did not injure me in any way and it serves to keep the tool concealable and discreet. It is important to remember that this is a last-ditch option. There was absolutely zero damage to the edge from any of the materials that I used the Punch Ring on.

The corners that will contact the user are nicely beveled for comfort.

The leading edge is beveled to cause maximum discomfort for the person on the receiving end.

If you are looking for a compact, light weight, discreet, tool that will give you an edge in a sticky situation then the NukoTools Punch Ring may just be for you. Check them out on the NukoTools blog. These would make perfect stocking stuffers!
