Iron Fist Training

Let me state that this is not a tutorial on how to develop manos de piedra - "hands of stone" - which is the famous moniker of prizefighter Roberto Duran. My use of a provocative title may be misleading. For the record I don't subscribe to the idea that hands can be conditioned into something akin to an anvil . Hands did not evolve to break open body parts and certain traditional training methods to toughen them can wreak havoc. Actually, this post was inspired by an impromptu sparring session I had this past weekend (my first in quite a while) that resulted in the first two knuckles on my left hand to swell to frightening proportions. I wore cotton hand-guards that leave the fingers exposed, and while my striking force was left in reserve for the most part, apparently, that wasn't good enough. This is really the result of chronic damage from years of sparring. (Note to readers: When you feel pain from an activity, stopping said activity is advised.) A colleague told me I should perform pushups on my knuckles to avert future injury. Another suggested training on a more time-honored method: The makiwara. I don't think so to either one.

A grandmaster of Matsubayashi-ryu once told me that any respectable dojo should have a makiwara on the premises. A makiwara is a wooden striking post designed to develop punching prowess and accuracy, not to put callouses on knuckles. Karateka that have knuckles that look like they're jacked on steriods may look impressive and could be held as a perverse badge of honor. Ego trips like this can go either way as one Okinawan karate historian tells:

Arakaki's father often warned him about making large black callouses on his knuckles. One reason was that, as his father was a merchant, customers would, on seeing the swollen and deformed hands, be easily frightened away. Another reason was that local ruffians would often try to pick fights on the pseudo-karate-ka who flouted such grotesque trophies. 'After practice on the makiwara,' Arakaki told me, 'it is a good idea to wash one's hands in salt water (or urine) and then alcohol; if the skin is cut, always carefully sterilise the affected area.'¹

There's a market that offers a wide range of liniments with names like "Iron Hit Wine" and "Tiger Balm" that, while pricey at roughly $20 for a 2 oz. dose, provides a more sanitary method of treatment than urine. Once during an Isshinryu karate demonstration held for US marines on Okinawa, Tatsuo Shimabuku cut his hand while driving a spike through a slab of wood. There was no liniment or any first-aid handy, so in a pinch he applied some dirt to the wound to stop the bleeding.

I've never trained on a makiwara, which is supposedly of Chinese origin, not Okinawan as many believe.² Indeed, the Chinese method of "Iron Bone Hand" training, developed as a method for maiming and killing, appears in Article 20 of the Bubishi stating:

The Iron Bone Hand technique can only be developed through relentless training. After thrusting the bare hand into a container filled with hot sand on a daily basis for many weeks, the fingers gradually become conditioned enough to initiate the secondary stage of training. After thrusting the bare hand into a container filled with gravel on a daily basis for many weeks, the fingers will become even more conditioned so that the final stage of conditioning can be initiated. The final stage of conditioning requires one to thrust the bare hand into a container of even larger stones. This special kind of conditioning will lead to hand deformity and the loss of one's fingernails. Alternative training methods often include thrusting the bare hand into bundles of wrapped bamboo in an effort to condition the fingers for lethal stabbing and poking.³

There's a tenet of unknown origin that advises to "attack soft tissue with a hard-surface hand-strike, and a hard area with a soft-surface hand-strike." Hammerfist, shuto (blade-hand), and palm-heel use the fleshier part of the hand that tend to be less injurious than a closed-fist if your target area is someone's head. In boxing, heavy hitters occasionally break their hands delivering the KO punch, this in spite of wrapping their hands in plenty of gauze and donning 10 or 12 oz. gloves. You'll also never see a boxer hit any kind of a bag without gloves. And some karate men, such as Isshinryu's Angi Uezu, have been known to doggedly hit that makiwara bare-handed. Somebody's wrong here.
