Ever wanted to know how to turn your raw rattan training sticks in to this? 
Well please read on or view the how-to video 
Below is some information that I found the authors

What is Rattan?
1 Rattan is a "vine" which comes from a climbing
palm called Calamus; also known as the rattan palm. The rattan palm is found
in the tropics, primarily in South East Asia and the Indonesian archipelago.
Next to timber it is Indonesia's most important forest product.
The rattan vine has a long flexible stem that can grow quite long with
a diameter as large as 3.5-cm (1.5 inches). Rattan vines as long as 500 to 600
feet have been observed in nature. Due to its flexibility the rattan stem requires
support as it grows in the rain forest. Spiny leaves that grasp host trees as
the vine climbs into the forest canopy provide this support. The spines make
the collection of rattan very difficult.
Collectors harvest rattan from deep in the rain forest. They pull the vines
down from the forest canopy and remove the spiny leaves. Bare cane is carried
out of the rain forest and partially processed before being sold to middlemen
who then transport it to major cities for further processing. Small diameter
cane is usually dried in the sun and smoked over burning sulfur. Larger rattan
cane is usually boiled in a mixture of diesel oil and palm oil to remove excess
moisture. This boiling also removes natural gums and creates a barrier against
wood-boring beetles. Rattan material is water-resistant, but heating and steaming
cause rattan to bend easily.
Rattan is used in a wide range of products, the most important of which
is the manufacture of furniture. In the past much of the commercially harvested
raw vine was exported to overseas manufacturers. By the mid 1980's, however,
Indonesia introduced an export ban on raw rattan vine to encourage the manufacture
of rattan furniture locally. The government's intent was twofold: to add value
to the exported product and to conserve stocks of wild rattan.
Until recently almost all rattan was collected from tropical rain forests. With
forest destruction and conversion, the habitat area of rattan has decreased
rapidly over the last few decades and there is now a shortage of supply. The
Forest Department in Indonesia has become aware of the vulnerability of the
rattan supply and has begun a cultivation program aimed at safeguarding the
long-term supply of rattan cane for the industry. Commercial cultivation of
rattan appears to be viable and offers the best possibility for future supply.
Why Use Rattan?
2 Anybody who practices Filipino Martial Arts quickly comes
to love the burning smell that rattan gives off during training, but there's
a much larger rationale to using rattan than just a smoky aroma.
To the uninitiated, the choice seems to be a needless expenditure. Why
not just go down to the hardware store and pick up some hardwood doweling or
PVC piping? A stick is just a stick right?
Actually, there are several reasons to choose rattan, and the overriding
concern is safety. Most hardwoods are, in fact, hazardous as a material for
training batons. When cut from a larger piece of timber, the wood fibres are
severed. The grain patterns that shows up on the wood marks the ends of the
fibres, and are essentially fault lines. After repeated impact, the fibres will
part suddenly, sending shards everywhere.
Rattan, however, is a vine, composed of numerous fibres running the whole
length of the stick. After many repeated impacts the rattan fibres will start
to shred. There is never an immediate failure of the material, only a gradual
breakdown. Compare this with hardwood or PVC piping, where the material might
appear undamaged, but at any moment could shatter. Unlike rattan where the ends
will be harmless, frizzy lumps, wood creates knife-like pieces. And since these
shards appear at impact, they will also be traveling at ballistic speeds.
There is no way to tell when a piece of hardwood is thinking about fracturing.
A personal experience with this happened when doing some hard contact work with
red oak bokken. In the middle of sparring, my bokken suddenly felt much lighter,
and when I held up the tip, about half of the weapon was missing. My sparring
partner and I dove for cover, not knowing when or where the other end would
come down.
For FMA training, rattan is the ideal material. In addition to being less
risky than hardwood, its mild flexibility absorbs the shock of impact that would
otherwise be transferred to the wielder's hand. Prolonged stick-to-stick training
with hardwood will eventually lead to tendonitis and other joint problems.
This shock-absorption goes for being struck with a stick too. Rattan was never
used for real fights, duels or warfare since it has much less killing or wounding
potential. Instead, blades or hardwood sticks would be the norm. Rattan is for
training, weapons are for fighting. This doesn't mean that rattan can't hurt
you - the Dog Brothers have demonstrated that often enough by knocking their
opponents cold.
A new field for sticks is the use of modern synthetic materials. These are
essentially indestructible, eliminating the need to replace rattan.
Below is a method that I learned early on.
Please be careful and be sure to wear your oven mits.
MINORS! DO NOT ATTEPMT THIS WITHOUT THE SUPERVISION OF YOUR PARENT OR GAURDIAN!

Using a gas stove light eyes...
After 10 minutes or so, place raw rattan on eye to create a burn pattern...

After 10 minutes or so, place raw rattan on eye to create a burn pattern...

Slowly but carefully rotate and draw the body of the stick back and forth to colorize the rattan to desired shade (WEAR OVEN MITTS)...


Next use an oil to lubricate and add a sheen to the sticks, here I used olive oil, you could use mineral oil as well...


Next heat oven to about 375...

Place sticks inside oven, for about 15-20 minutes this is to harden the sticks. Please DO NOT leave unattended.

Finish up by wrapping the ends with metal repair tape found in most hardware or plumbing stores and/or you can coat with shellack or aresol polyurethane for a shiny finish and to aid in strength. VOILA! Your new decorated Escrima sticks!
