The Bear Grylls Gerber Fire Starter - quick review and comments

When I was browsing in a DIY shop I happened to see this product. Although a bit overpriced at RM78, I still decided to get it asI am curious about the quality and effectiveness of a fire starter.

We tend to associate fire starting with matches or a lighter. We know of traditional methods of rubbing things together to generate heat and hence flame (never tried it because it takes a lot of effort). However, there is another method which is seldom talked about. Making fire by generating sufficient sparks from fire starters. Fire starters are usually made out of flint, metal and magnesium.


This fire starter from Gerber was made in collaboration with Bear Grylls, the famous survivalist. It features a coompact fire starter with ferrocerium rod and metal striker; lanyard to keep the stuff secure and together; emergency whistle which is integrated with the lanyard; waterproof storage for tinder; and a pocket guide on survival essentials. 

Interestingly, Gerber provides lifetime guarantee for this product.


The Bear Grylls pocket guide on "Priorities of Survival" is rather useful. However, I would have preferred it if was made in a small booklet form instead of a "folding piece of paper" form.


The fire starter itself. The lanyard keeps all the parts together. It is not long so you cannot hang it around your neck. Nevertheless, if you open the storage compartment for tinder, a main part of the fire starter will not be connected to the lanyard and can be misplaced. More about this later.

The small whistle is located at the locking ball on the right of the photo below.


The whistle.


The main tube splits into two where the first part is the ferrocium rod and the other part contains the metal striker. By striking the rod with the striker, sparks will be generated. Note that the rod is covered in black substance. This must be cleaned first to reveal a silver-like surface for the product to generate a good amount of sparks.

Also note that it is best to keep the striker in a fixed position and only move the rod away from it so that the sparks would fall consistently on a targeted area.

On the tube itself you can see the various signals for air rescue instructions and SOS.


The end-cap which is connected to the lanyard pulls open to reveal the water-tight storage compartment. This is one area of design which Gerber should consider re-looking into. I would have a connecting thread from the storage tube to the end-cap. This will definitely eliminate the chance of missing parts.


Overall, a good product. The sparks are also very bright and substantial.

Cheap blowgun made out of PVC, paper and tape

If you have view my earlier posting on how to make a blowgun (Simple instructions to make a blowgun), here is an actual product from the short instructional video. For just RM6.45, I got myself a 6 feet 6 inches 1/2 inch pvc conduit which I got the shop to cut into two equal halves as well as two reducer for the mouthpiece.



Here the mouthpieces are attached to the end of the roughest surface of the time. No glue needed as it is tight enough just from the friction. At this stage, you need to make sure the pipes are relatively straight. If it is not, slowly bending it will make the pipe straighter.


To make the dart is easy. Paper cone and a sharp point is all that is needed to make a straight-flying dart. If you don't have hot glue, just use tape to keep in all together. Below is a dart made out of toothpick.


Here is a dart made out of 2 inch nails.


Here is a dart made out of a screw.

Bought a Dremel high speed drill for some DIY project - Part 01

Last week bought myself a  Dremel (Dremel 3000) high speed drill for some DIY projects I have in mind. For the last month or so, got the mood to do some DIY projects. Some of the DIY projects I got interested in are:
  1. Rocket stove
  2. Hobo stove
  3. Wood carving
Last weekend I got my chance to make a (1) & (2) combo. I didn't get a chance to take a picture but let me describe it in words on what I did.

I got a big square biscuit tin and cut a 3 inch wide by 2 inch high hole approximately 1 inch from the base. This hole is where wood and twigs will be fed into the stove. That's it.

To test, I stuff a crumple newspaper into the top of the tin (the opening where you get access to the biscuit) and then I put in a few sticks. I light it up. Within a minute, a roaring fire can be seen jetting out of the top of the tin box. You can also hear the sound of like a jet engine hence the term 'rocket stove'. As the fire burns and heats up the air in the box, the air starts to expand and escape up the top hole. The displaced air in the tin creates a vacuum that then sucks fresh air from the outside via the cut hole made earlier. This in in turn helps fuel the flame and the process (or cycle) repeats itself.

From an energy efficiency aspect, this helps to direct the heat in more-or-less one direction i.e. to the top unlike an open flame where the energy spreads out everywhere. By placing your cooking pan at the top hole, you have cook a meal with a small amount of fuel.

I will try to take a video next week.

The making of a miniature rocket stove or cannon (Part 01)

This past month I have been bitten by the DIY bug. One of the first projects I was interested in was the making of a bow (to fire arrows) from just PVC tube, some plastic rods and a length of para-cord. My focus was then diverted to the making a cooking stove using the concept of the 'rocket stove effect'.

The first project that I decided to venture into was the making of a miniature rocket stove using bits and pieces that one can find in hardware stores. For this project, a minimal amount of handiwork is needed.

What you need from the hardware store are the following (see the following photo).


  1. Two (2) T-junction pipes;
  2. One (1) connector tube;
  3. One (1) plug;
  4. One (1) tapered tube.

Tapered tube

Screw in the connector tube to the two T-junction pipes.



Screw in the Tapered tube into the end of one of the T-junction pipe.


Plug the hole on the T-junction pipe that is in the middle of the contraption with the plug.


A rocket stove is now ready.


To be continued.

DIY: Recycle, decorate and create an awesome photo/hanger combination

Saw this picture on the internet about a DIY project that uses an old glass panel door to create a photo gallery as well as wall hangers. Instead of photos, you can substitute it with small paintings etc.
