Remember, training is not recommended at all for those under 16 years of age. Those individuals under 18 years of age must get permission from a parent or guardian before starting training. Always consult a physician before beginning any exercise program. Train at your own risk.

BOARDS | STICKS | BLOCKS | OTHER | CHEATS

The materials used in tameshiwari is the topic most often neglected by books and articles involving breaking. Only through working with the materials available to me in stores have I become familiar with the variations. Here I will describe the properties of the materials most readily available for retail.

WOOD BOARDS- Boards are the entry level material for breaking. The standard cut is 12 inches wide and 10 inches high. The standard wood used is white pine. Avoid wood with knots that run along the board. Small round knots are not too troublesome. If you are looking for a challenge, try some hard woods, but don't be surprised if people aren't impressed with you having trouble with one or two boards. Also, wood cut into boards much ahead of breaking time tend to dry out and crack on their own.

Everyone tells you to break the board along the grain but few get into detail about the varying grain widths of boards. Since you are merely splitting the board along the grain, a wider grain is naturally better (easier) for breaking. However, you should take note of the type of grain in relation to the cut. If you see grain only running vertically in bands, it is a easier cut since you are going to split the board along one of the grain bands. If you see wider, flat bands (often v-shaped) in the center portion of the board, you will have a harder time since the cut is more difficult for breaking and you must actually break through some grain structure.

With single boards, this difference is negligible, but when breaking large stacks, it can add up to make a significant difference. *Try punching, chopping, and slapping through five or more boards without spacers. Set a stack of ten with spacers for the knife hand.

WOODEN STICKS/PLANKS- By this, I mean any sort of wood that you are attempting to break against the grain. In this case, grain that runs in bands along the length of the wood is not desirable. The opposite of board breaking, here you want a grain that runs wide and flat. When you look at the end of the stick (such as a 1"x2" plank) the grain should run horizontally or at least diagonally. If the grain is vertical, you are going to have a harder time. This also applies to breaking wooden baseball bats.

*Start with a 1"x1.5" pine stick cut to a length of 18". Increase the thickness and decrease the length for a greater challenge. I find the knifehand best suited to this technique.

PATIO BLOCK- After getting comfortable with wood breaking, this is a good introduction to brick breaking. Patio blocks are common in brickyards, garden stores, and big chain hardware stores. Home Depot has them almost all the time and these are the most consistent in strength. Though actually slightly smaller, their dimensions are listed as 8x16x2". They are made of cement with a small amount of reinforcement aggregate. This refers to the additional rock chips and pebbles mixed into the block to further strengthen it. These blocks most often come in gray and red. They can be flat on both sides or the bottom can have small gripping ridges. The color makes no difference, thought the additional ridges may make it very slightly stronger. These blocks can easily support your weight plus a couple of your friends, so don't be disappointed if you find them difficult to break. Patio blocks are good for their consistency in difficulty, although a wet or frozen block is harder to break. They are usually left in the rain in brickyards so let them dry out a few days after you buy them. This applies for any sort of manufactured block or brick. Do not attempt to dry them in the oven, as this constitutes tampering.

One patio block equals about five strong boards and easily supports much more than my weight at 190lbs (pictured above). Whereas boards can cost $2 a piece, patio blocks are about 80 cents a piece. Try any technique you wish, but believe it or not, the iron palm works the best. Work up to two or three blocks without spacers. If you can break two or three, your doing well.

REINFORCED PATIO BLOCK- Watch out for these newer patio blocks. There are blocks that look similar to standard patio blocks but are several times stronger. They are listed as the same product, so you must be familiar with their appearance. Break one of these open and you will find a lot more filler consisting of rather large granite chips or other material. If you drop a block on the floor and it does not break, you probably have one of these.

I recommend breaking one slab at a time with iron palm. Proceed to two if you dare.

OTHER MATERIALS- There are several different other kinds of breaking materials, each with its own considerations. Ignorance of the characteristics of materials can lead to embarrassing failed demonstrations, discouragement in training, and susceptibility to breaking frauds. Other materials include ice, stones, cinder blocks, tiles, clay bricks, coconuts, etc. If you would like to order a more in depth description of breaking materials complete with illustrations click here.

METHODS OF CHEATING (FRAUD)- Some iron palm purists consider the use of spacers as cheating. I do not. Spacers produce a different kind of challenge requiring penetrating force and the fact of the matter is that iron palm slapping simply does not work well on spacer breaks. I can chop through 10 scalloped blocks with half inch spacers but I cannot slap through more than two. On the other hand, I can slap through four or five without spacers, but cannot chop through more than two or three. You have to understand the challenge offered by each method.

Holding bricks up above the support for breaking is cheating. This creates a slamming effect with the support block. You are no longer breaking the brick yourself, merely smacking it against another object. This same theory applies to holding up two bricks with a space between them or standing two blocks together with a slight space so that you can strike one, causing them to slam together and break on impact. If you do not explain the difference of the method to the audience, it is fraud.

While patio blocks are fairly stable, red bricks and some other blocks will weaken if left in the sun. Baking bricks has the same effect and is completely fraudulent. Bricks can also vary greatly in hardness due to the manufacturing process. Bricks bought from a yard from the same pile can vary due to sand content as well as exposure to the elements. Generally, lighter colored bricks are easier to break.
