Small Surface Strikes & Structural Support

General Information On Small Surface Strikesknowledge often lacking in modern karate-do but commonplace in "old style" karate

Small surface area strikes were very common in old style karate. In modern karate-do, the

existence of these strikes is generally remembered, but they are rarely practiced. Even when

they are practiced, the structural strength of the hand formation is almost never tested

through hard impact against suitable surfaces. This has resulted in a degradation of

information about these techniques. With generation after generation rarely practicing these

techniques and never testing their strength, some of the important keys to hitting with these

strikes were largely forgotten or at least not emphasized.

Pick up any comprehensive text on modern karate-do and you will see most of these

techniques in pictures. If you look closely at the pictures you can tell that the person in the

photographs has never hit anything with them with any real force, and that if he attempts to

do so, the structure would most likely collapse due to joint buckling. However, with a little

guidance it is easy to learn how to form these weapons in a way that will not collapse (at

least not until *much* higher levels of force are applied).

So, here are few tips from old style karate on how to brace the joints which are likely to

buckle and how to create structural support which is aligned with the direction the force

travels. These tips are all pretty simple affairs but in most cases will at least double or triple

the amount of force which can be successfully applied. In some case it is even higher.

I apologize for the fact that the wrist angle is wrong is many of these photographs. I was

taking pictures of my own hand which was usually placed against a wall right in front of me.

This resulted in awkward wrist angles but since this article is about hand formations this

defect doesn't impact the value of the photographs.

I should clarify that my use of the word "useless" doesn't mean there will be zero effect.

Generally you can get some effect from those hand-forms. However, the hand form itself

offers little support to the structure of the striking weapon and it is likely to buckle in some

way when significant force is applied. At minimum it will not be nearly as effective and useful

as the methods I call "effective" and "optimal".

Ipponken (Keikoken, Shoken etc)

Notice how the above fist form has nothing *behind* the index finger. It is impossible to do

foreknuckle push-ups on this structure. It makes a very poor striking weapon because it

obviously has very poor structural support and joint bracing.

The above hand-form has good structural support and joint bracing and it would be possible

to do push-ups on this fist. However, it can only penetrate as deep as the tip of the thumb

making it just slightly less than optimal.

The above hand-form has good structural support and joint bracing and it would be possible

to do push-ups on this fist. It can penetrate as deep as the knuckle of the thumb (slightly

deeper than the one above it) making it the optimal Ipponken.

Nakadakaken (Nakadaka-Ipponken)

3/13

Notice how the above fist form has nothing *behind* the middle finger. It is impossible to do

push-ups on this structure. It makes a very poor striking weapon because it obviously has

extremely poor structural support and joint bracing.

Because of the straightened index finger, the above hand-form has good structural support

and joint bracing and it would be possible to do push-ups on this fist. It is the optimal way to

strike with Nakadakaken

Nihonzuki (Nihon-Nukite, Secret Sword, Two Finger Strike)

Neither the thumb nor the two bent fingers offer any stabilization or structural support. This

hand form somehow crept into Chinese martial arts from Chinese folk magic and folk

medicine where it is very common. Those two endeavors require no strength in the structure

so joint bracing is a moot point. Martial applications on the other hand do require structural

strength.

The thumb and bent ring finger offer some stability and structural support and it is easy to put

rigid strength into the hand and fingers in this position (unlike the ritual mudra above it). This

makes it effective for striking soft areas of the body.

The thumb and bent fingers offer a stability and structural support and it is easy to put rigid

strength into the hand and fingers in this position. Notice how the middle finger is pressing

again the back of the index finger (and reciprocally the opposite) creating decent joint bracing

in a way the hand-form above it does not. This makes it the optimal position for the two finger

thrust.

A side view allows a better look at how the thumb provides structural support. You also get a

different view of how pressing the index finger into the middle finger (and reciprocally the

opposite) creates some additional joint bracing.

Ipponzuki (Ippon-Nukite, Single Blade of Grass)


13 21/04/201300.41


5/13

There is no structural support for the index finger whatsoever in the above hand form

The thumb and bent fingers press very firm against the index finger creating good joint

bracing from two directions up to the second knuckle of the index finger. There is also a

general firming of the fingers and hand proving a little additional stability and support.

Although this is the optimal hand form, it is still a weak structure and is only useful against

very soft targets. However, if it is used against the right areas it can still produce devastating

effect.

Nukite (spear hand)

Because the middle and ring fingers are bent and merely stacked on each other, this

structure will easily collapse if significant force is exerted as a finger tip strike. It also makes a

very poor thumb strike (and will likely result in self-injury if used in that way).


13 21/04/201300.41


6/13

Notice how the back of the index finger presses against the front of the middle finger (and

reciprocally the opposite) and how the back of the pinky presses against the front of the ring

finger (and reciprocally the opposite) creating as much support and joint bracing as is

possible for a "spear hand" finger tip strike. Notice how the thumb is in good alignment to

strike as well.

Seen from above, this is the optimal position for a finger tip strike.

Notice how the thumb separates from the index finger up to (but not beyond) the first knuckle

of the thumb. This is the optimal position for the "tip of the thumb strike" application of nukite

Boshiken (Thumb Strike)

Nukite side view (thumb and finger impact look identical from the side)

Nukite - fingertip impact (viewed from above)

Nukite - thumb-tip impact (viewed from above)

7/13

Notice how the thumb knuckle is bent making joint collapse much more likely. It is impossible

to do push-ups on this fist form (thumb push-ups)

Notice how the thumb knuckle is straight making joint collapse much less likely. It is definitely

possible to do thumb push-ups on this structure.

The superiority of this structure is easily felt/tested on a Machiwara

Rarer Information Abou t Small Surface Strikes

I actually feel a reluctance to share this information despite my general dislike of secrecy.

Anyone who has been around the Okinawan martial traditions for a while will notice that

some Okinawan teachers can use a few techniques with dramatically more effect than any of

their Western students (and often their Okinawan students as well). We'll call these the

"specialty techniques". In most cases students just say "wow, sensei can really put the hurt

on with that" (or something similar) and never stop to ask WHY they are not able to do the

technique to the same effect. Even those who do ask this question often only get part of the

answer right. For instance, they will conclude their teacher has a lot of power and has

developed very strong fingers through years of Hojo-undo. Generally this will be true, but as

with most things in life, there is usually a bit more to the story. Not only can these teachers hit

with more force, but they are usually doing their "specialty techniques" in a way that is

ever-so-slightly different from their students. There are only two ways to learn these

differences. The first is to become somebody the teacher is very fond of. The other way is to

first become aware that a difference even exists, then to repeatedly *feel* and keenly

observe the teacher doing his "specialty techniques" (if possible in close up frame-by-frame

slow motion).

I don't know the secret to many such "specialty techniques"... but I do know the keys to a

few. This was hard won knowledge, and I have to admit I have loved having these as my own

"specialty techniques." It is quite cool to be able to do a few techniques in a way which

produces dramatically better results than 99% of karateka. If looking cool and cultivating an

impression of a very high level of skill were my main goals, then I would not share these. I

would greedily hoard them for myself. However, as a friend recently said: the real secret of

karate is that everything you share you will still have, and you will be given even more in

return.

My goal is to learn and preserve "old style" karate as best as I possibly can (not look cool).

Preservation means sharing. So, despite feeling a bit of loss at no longer having these

"specialty techniques" for myself, I want to share what I can of the few I know (these are just

the "specialty techniques" which relate to the structure of small surface strikes).

Shi-zuki (Washide-uchi, Beak Strike, Gojush iho st rike)

Poorly supported in that the force isn't focused on a single well supported structure. It is too

blunt to make a good strike behind the collar bone or to the Brachial plexus, Scalene

muscles, or Omohyoid muscles.

The above uses a single well supported structure (the index finger) and the force is

concentrated into a very small area and this is easy to slide behind the collar bone. It is also

great to attack the Brachial plexus, Scalene muscles, or Omohyoid muscles. I'm told this

technique is still remembered in several kung fu systems (which is second hand info since

I've studied no Chinese martial arts)

The above hand form (like the one above it) uses a single well supported structure (the

thumb) and the force is concentrated into a very small area. It is easy to access the area

behind the collar bone with this hand form. Like the previous technique it is also great to

attack the Brachial plexus, Scalene muscles, or Omohyoid muscles. The reason it is

considered optimal is that the thumb is an inherently stronger structure and can deliver

considerably more force than the index finger. Otherwise the "effective" and "optimal" are

very similar.

To form the optimal structure, press the index and middle finger against the pad of the thumb

with the tip of the thumb protruding. Then brace the side of the thumb with the remaining two

fingers (ring finger and pinky).

Test the difference for yourself

Compare the "useless" and "optimal" versions of Shi-zuki by lightly striking the area shown

above at an inward and downward angle. The "useless" version will likely only cause a wince

reaction from pain. The optimal version will likely drop your partner to the floor with even

relatively light force. Despite looking essentially identical, the two methods produce

dramatically different results. So there you are, now you have Shi-zuki as your own "specialty

technique".

Hidden Foreknuckle Punch

This is the most powerful but least well known of the foreknuckle strikes. The hand is in the

normal fist formation but the hand/wrist is angled so that the foreknuckle of the index finger

makes initial contact. This is the only foreknuckle strike which can be executed with the same

force as a person's normal punch. It is not suitable for striking most parts of the head but is a

devastating way to punch the torso. It is called a "hidden" strike because when executed at

normal speed it is indistinguishable from seiken-zuki. Even at very slow speed it usually will

be mistaken for seiken-zuki (and thus makes you look really good if you don't tell people

what you are doing) ;-)

Iron Bone Hand (thumb knuckle striking )The following set of pictures illustrate a series of thumb strikes that are all done with the

same hand formation. This hand formation is only briefly mentioned in the bubishi and is

rarely seen in modern karate-do. Karate-do generally mistakes the first technique with a

spear hand (or, depending on the wrist angle, sometimes even a palm strike). The

subsequent three techniques are usually mistakenly regarded as "ridge hand strikes". If you

were taught how to practice these techniques you most likely study a lineage with a fairlyintact connection to the "old ways" IMHO.

Maximum Force Foreknuckle Strike (Seiken type hand formation)

Iron Bone Hand (thumb striking): Neutral Position


of 13 21/04/2013 00.41


11/13

Strike is applied with the force moving forward and slightly down and is done in the "Neutral

Position". It relies on directing the force in alignment with the proximal phalanx. To strike with

force it is very important to firmly press the thumb into the hand in order to create structural

stability. This is often used to attack the carotid artery (especially at the bifurcation).

Immediately after the strike the fingers grip the sternocleidomastoid muscle from the outside

and the thumb (now inserted deep into the neck just inside the sternocleidomastoid) grips the

muscle from the inside. After the grip is secure a very powerful jerking pull is applied as if

trying to tear the muscle free from the neck. This is not something to do to friends.

Notice how the Nigiri-game grip uses the same thumb knuckle in the same way as the

muscle ripping grip discussed above. Likewise the finger tips grip into the lip of the jar in the

same way they are used to dig into the neck. These same features are found in many of the

nasty gripping techniques in karate. This is why Nigiri-game training was always regarded as

essential in "old style" karate.

Starting from the "Neutral Position" this strike rotates as it moves and slight unlar divination is

applied as contact is made (see picture above). The force is concentrated on the knuckle of

the thumb closest to the nail. Because the thumb is braced against the hand a very large

amount of force can be delivered with this innocuous looking strike.

Reactions:

Starting from the "Neutral Position" this strike rotates as it moves and strong unlar divination

is applied as contact is made (see picture above). The force is concentrated on the second

knuckle of the thumb (the distal end of the 1st metacarpal). Because the thumb is braced

against the hand a very large amount of force can be delivered with this innocuous looking

strike.

Same basic method with force distributed along the length of the proximal phalanx of the

thumb.

I've been forming keiko-ken and nakadaka ippon-ken almost exactly the way you

show as "optimal", and have had no problems. Interestingly, Doug Perry also braces

the tip of his thumb inside his curled middle finger when he does keiko-ken, and that

seems to work quite well for him. I've been experimenting with some of the others to

try to find some better hand formations for them, and I came up with a very similar

nukite formation, but have been pretty stuck with washide. My system doesn't really

make use of the other strikes, so I've never played with them, but now I will have to.

Thank you for this post, Ryan!
