The Cane: Part 5 – Two Hand Weapon Retention

Retaining control of your cane is of primary importance and a two-hand grip is a significant advantage.

First, the two-hand grip is simply stronger. Your opponent has to work harder to wrest control of the cane from your secure two-hand grip. Second, it’s flexible and gives you immediate options for countering your opponent’s attempt to take your weapon; to turn your defense into an attack.

There are three two-hand cane retention strategies.

1. Convert the attempt to take your cane into a strike with the free portion of the cane. This is sometimes called a shield strike. Shield strikes are appropriate if the opponent grabs one end of the cane. You can strike with the opposite end of the cane using a horizontal or vertical butt stoke; even if the free end of the cane is the tip instead of the crook

2. Use the opponents grip on your cane to draw him into a strike with a different weapon. A head butt or a kick are typically set up in this situation. If the opponent grabs the center of your cane or grabs both ends at the same time you can pull the cane towards your own body and simultaneously drive your forehead into your opponent’s nose or sidekick his leading knee.

3. Use the opponent’s grip on your cane as your grip on him and execute a throw. If your opponent has a secure two-hand grip on your cane you can move the can in a direction to off-balance him and set up a judo throw. For example, by moving the cane to your left you can shift your opponent’s weight in that direction and set up a right side o-soto-gari throw.

When retention of your cane is threatened, the flexibility of your two-hand grip should be used to immediately convert the threat into an attack (parry-repost).

The Cane: Part 4 – Two Hand Cuts

A cut with a stick is a special kind of strike; the way it’s delivered looks and feels like a cut with a saber, broadsword, or katana. It’s called a cut because of this similarity. Since the stick or cane has no sharp edge it doesn’t cut the opponent. But a well delivered cut with a cane damages bone, cartilage, or tendons.

Two-hand cuts are delivered using katana techniques. With the katana, the Japanese two-handed saber, the objective is to rapidly pull the edge of the blade through the opponent letting the sharp blade slice through. It's not a power cut.

The katana cut is a coordinated finesse technique in which the hand near the kashira (pommel or butt of the handle) pulls while the hand near the tsuba (guard) pushes so that the katana rotates forward around a point in the middle of the two-hand grip.

At the same time the arms swing the katana in an arc centered on the swordsman’s torso. The result is two distinct forward motions. The two motions combine speeds resulting in a much faster cut than can be achieve by swinging the katana with the arms alone.

Lacking the sharp blade of the katana, the cutting strike of the cane delivers kinetic energy to the target. You might think that putting more arm and shoulder muscle into the swing increases the power of the strike. But kinetic energy is ½MV² where M is Mass and V is velocity. In the cane cut, the mass is roughly ⅓ of the mass or weight of the cane. This corresponds to the portion of the cane actually delivering the blow. Velocity is the speed of the cane at the moment of impact on the target.

But the formula is KE = ½MV²; the speed is squared. The formula could also be written as Kinetic Energy = ½*⅓*Weight of the Cane*Speed of the Cane*Speed of the Cane. I won’t spend any more time on the formula except to point out that doubling the speed of the cane multiples the kinetic energy delivered to the target four times.

The katana technique, rotating the cane with the hands while swinging the cane from the shoulders, increases the speed of the cane at impact. And, as discussed, increasing the speed of the cane squares the delivered kinetic energy.

The two-hand cut can be delivered vertically downward, horizontally, or diagonally.

A well delivered two-hand cut delivers damaging kinetic energy to the target.

The Cane: Part 3 – Two Hand Strikes – Butt Strokes

A two hand grip increases the power of a straight thrust, the security of a block or parry, and enables the use of the crook end of the cane in vertical and horizontal butt strokes.

In all cases the forward grip can be underhand or overhand; the underhand grip allows a more natural stroke but requires a grip change from most starting positions; the overhand grip does not require a grip change from most starting positions.

Butt stroke techniques available with a two-hand grip on a crooked cane include:

Upward Vertical butt stroke:
· The striking surface is the horn (or end) of the crook
· The target is the lower jaw or chin
· The strike rises vertically toward the underside of the opponents jaw as in an uppercut punch

Forward Horizontal butt stroke:
· The striking surface is the horn (or end) of the crook
· The target is the hinge of jaw
· The strike swings in from the outside with a pushing motion toward the side of the opponent’s face as in a hook punch

Reverse Horizontal butt stroke:
· The striking surface is the top (or back) of the crook
· The target is the hinge of jaw
· The strike swings in from the outside with a pulling motion toward the side of the opponent’s face as in a side back fist punch

Straight forward butt stroke:
· The striking surface is the back of the crook
· The target is the bridge of the nose
· The strike moves straight forward in a horizontal line into the center of the opponent’s face

Two hand butt strokes with the crooked cane come straight out of military bayonet drills. They are effective, easy to learn, and easy to use. They are excellent techniques for a cane novice.

The Cane: Part 2 – Two Hand Strikes - Thrusts

When starting out with the cane as a weapon of self-defense, two-handed techniques based on bayonet drills are the most secure and effective.

Holding the cane with both hands improves your ability to control your cane when your opponent grabs it. Retaining control of your weapon is just as important as executing effective techniques.

A two hand grip increases the power of a straight thrust, the security of a block or parry, and brings the crook end of the cane into play as a striking surface. Vertical and horizontal butt strokes are of little practical valve with a one-hand grip; but with a two-hand grip they are important tools in your tool box.

Two basic thrusting techniques are available with a two-hand grip on a crooked cane. They are:

Lunge with thrust:
· The striking surface is the cane tip
· The target is the abdomen, solar plexus, Adam’s apple or the bridge of the nose
· A forward lunge is executed simultaneously with the two-hand forward thrust
· The forward grip can be underhand or overhand; the underhand grip allows a longer thrust but requires a grip change from most starting positions; the overhand grip does not normally require a grip change.

Back stance with thrust:
· The striking surface is the cane tip
· The target is the abdomen, solar plexus, Adam’s apple or the bridge of the nose
· A shift into a back stance is executed simultaneously with the two-hand forward thrust
· The forward grip can be underhand or overhand; the underhand grip allows a longer thrust but requires a grip change from most starting positions; the overhand grip does not normally require a grip change.

Additional two-hand techniques will be described in future posts.

The Cane: Part 1 – Types of Canes

My favorite weapon is the crooked cane. It’s legal to carry and it’s more acceptable to carry as you age. It’s also very effective.

There are many kinds of canes. Although crooked canes are the most versatile weapons, most of the canes you see on the street have straight, often padded, handles. Lengths vary with the height of the person using them and many canes are adjustable. Some canes have three or four tips. All of them can be effective weapons.

I’ve experimented with several styles of crooked canes and I recommend the wide-crook canes sold by Cane Masters. The wide-crook makes it possible to hook your opponent’s neck, calf, or thigh. Canes available in pharmacies and medical supply stores generally have crooks too small for these targets but they can be used to hook a person’s ankle.

Canes from Cane Masters also feature grooves cut in the neck, the transition area between the crook and the shaft. Since the neck and the crook are the most common gripping points for one-handed techniques the grooves improve your grip on the cane.
Cane Masters also offers instructional material for using the cane as a weapon which I found of little value.

Although you have to hunt for them there are many books, some very old, on using the cane for self-defense. From a number of these books I’ve developed a personal cane system compatible with Neko Ryu Goshin Jitsu philosophy and principles.

The crooked cane is an effective legal personal defense weapon. I‘ll describe my cane system that I call “Neko Ryu Cane” in future blogs.
