Introduction:

My elder brother and his friends do lot of trekking tours, almost at every weekend they plan to explore new places. Mostly they plan to visit forts because they all are devotees of “Shree Chatrapati Shivaji Maharaj” who have built more than 250 forts (over the mountains) in our region.

They generally carry fruits and ready to eat food. Essential items they carry are knife, lighter that’s all. But to climb mountain (almost every fort is located at mountain) everyone needs a strong bamboo stick.

Bamboo stick have two uses 1)to assist climbing 2) For protection from wild animals (mostly monkeys). Once my brother’s friend was attacked by a monkey and that friend don’t have stick and his knife was in his bag pack. So from that incident I was thinking about making a folding “all in one” bamboo stick which will carry all essentials things. I design a basic version first and then modify it as per need. I made this stick in two parts so we can easily carry in our bag also try to keep total weight is about 200 Grams. Once stick assembles then it can convert into spear, bow and a fishing rod. It has knife very handy and a compass to check direction whenever you want.

Step 1: ​Material Required

As usual i am using material which is easily available. these are not detail pictures, but you will see all in next steps.

1. 3/4 “ PVC pipe - 32” long

2. ½”PVC pipe- 08” long,

3. Bamboo (for making strips)- 32” long

4. Epoxy glue (I used Bondtite)

5. Angle grinder- (Optional)

6. ½” dia compass

7. Fishing thread

8. Wooden coupling(details given below)

9. Old hacksaw blade or good knife

10. Some rubber bands, cloth pins, paper clips

Step 2: ​Making Knife:

I am not a professional knife maker but believe that we can easily convert any metal piece to knife. Here I made knife from old hacksaw blade. This blade is 1/16” thick and 1.5” wide. First I cut it along length and give knife shape with angle grinder. I kept hacksaw blade teethes as it is, they don’t have any use but just add nice look to knife. Then sharp it with angle grinder and then add a bamboo handle (1” dia).

Hacksaw blades are extremely hard due to its carbon content. They are not ideal for survival knife as they are brittle. But if we keep its length short (I kept here around 7”) then they don’t break easily if fall on hard surface.

Step 3: ​Making Stick

For stick we can use bamboo itself but I want to add a bow function to “trekking stick” so I decide to make stick from composite material. Inner core is a made from stiff PVC tube (1” OD) and outer cover is from bamboo strips. My brothers height is 5’8” so I select stick size 3’2”(find out with trial and error, it’s a minimum length require to walk comfortably for 5’8” high person).

For making bamboo strips, cut bamboo in half and continue cutting till you get ¼” wide strips. Clean all buds and inner useless core. Now with help of epoxy resin stick all bamboo strips around PVC pipe. I have used O4 full length main strips and then short strips to cover PVC pipe.

Due to its composite design I have lot of free space for storage and its weight also reduced. I believe Its strength also enhanced compare to normal bamboo stick.

Step 4: ​Knife Installation

Knife will assemble in top portion. So any time we can use it as it is always present in hand. For spear arrangement I have to make strong coupling arrangement so I make a small threaded piece which will bond at handle’s end. I also installed a small compass in threaded end.Knife installation

Step 5: Making Folding Stick

Detachable is proper word but anyway I will use “folding” word. To make it separable we need to cut our stick in half (at 21”).

I have designed two joining processes

1. A threaded coupling

2. Hollow sleeve coupling

I have tried both, but for now I will show you “metal threaded coupling” and in my next version I will update it to “hollow sleeve”.

You can see pictures of metal coupling, it is two part coupling, each part accommodate “stick’s” one end. Coupling is made from MS piece of 50 mm dia. Threads are M16. Its weight is 130 grams.

Step 6: ​Making Spear Attachment.

We have already installed knife at top, to attach knife handle to stick we already provided ½” NPT threaded piece to handle. So I installed threaded nut at bottom of stick.

To make spear just remove knife and attach at bottom of stick with thread.

Step 7: ​Making Bow and Fishing Rod

Its only contraption bow, but still we can make use of it. i attached two wire loops at each end,I kept some measured thread in stick and also did thread installation arrangement to stick by providing hooks. Just added small loops at each end which will hold thread. There is some space for arrows if you want to keep them. And with same thread and some extra thread we can make a fishing rod.

Keep lures, baits at storage space.

Step 8: Conclusion

My main aim was keeping project size (length and weight) minimum as possible. I measure weight and its come 210 grams, and it requires storage space of 16” length and 2.5” dia.

This is very basic idea, and there is more to do with it.

#Happy making.

Does the bow work?
<p>I HAVE DONE IT</p>
<p>cheers :)</p>
<p>I FAILED AT IT</p>
<p>1 TIME</p>
<p>nice</p>
<p>thank you :)</p>
<p>Excellent effort. voted for both contest.</p>
<p>thanks you Chris :)</p>
<p>As a hobby hiker, I have some vaguely similar items, and some suggestions. While a makeshift spear is a really nice tool, and excellent for defense against small and medium animal threats, it also makes this a overt weapon. For use in the US, where animal threats are usually smaller, I'd suggest keeping your knife separate, and instead drilling out the bottom of a solid hardwood staff and adding a weight. While this is less desirable for walking purposes, it adds a lot of energy to the end of the staff when swung. I have fended off feral dogs with one of these. Mine are weighted with lead, and then capped with a small steel pipe and end cap, but this is not environmentally sound. If I were doing it again, I'd probably use pre-made tungsten weights, and fill any gaps in the end with epoxy to make it fill the way lead did.</p>
<p>Thanks for your comment and suggestions.</p><p>I made it for my brother, his requirement was a folding stick with knife. He also asked to keep weight low so I tried to keep it around 200 grams. everything else I added is due to space was available for it.</p>
<p>Very cool.</p>
<p>Thank you :)</p>
It might help to add a small compartment for fishing line, hooks, matches and wrap some paracord on it
<p>ya, it have lot of space to store lines,hooks etc, I want to add some paracord at handle but i was out of it.</p>
Does the bow actually fire? looking at it i can't imaging it would. but given that im not inclined to build on I'll just have to take your word. Great craftsmanship regardless. cheers
<p>Thanks for appreciation,</p><p>Its a contraption bow arrow, not full functional . but still can shoot from 20 feet. I recorded video with trying every function, soon i will post.</p><p>and for full functional bow, we need to couple two sticks with hollow sleeve coupling, this coupling is a 1/2&quot; PVC pipe that join two sticks, and act as spring when use as bow.</p>
<p>COOL IDEA BUT I DO NOT THINK MT SCOUT TROOP WILL LET ME USE IT.I LOVE IT</p>
<p>Thank you for your comment, might be they will not allow you with knife, to hide knife you can easily installed a number coded lock, Currently i am working on that and will post soon. but before building something like this you must check your federal laws.</p>
<p>If you live in the US and are thinking about making this, you might want to check with the laws in the state you live in. Canes with a hidden knife are illegal in some states. </p>
<p>Thanks for your advice.</p><p>But i live in India, and here &quot;hidden knife&quot; is far away but carrying knife is also not permitted. Only &quot;Sikh Religion&quot; people can carry knife(Kattyar) legally.</p>
<p>get a concealed carry permit, or just sheath the blade on your belt, problem solved.</p>
<p>Concealed Carry permits apply to handguns/firearms only. You can legally conceal carry a handgun, and get arrested for openly carrying a knife. And knife laws vary by: federal (only applies to federal property), by state, and county. It is possible for county X to limit the max allowable blade length to 2&quot; while the state permits 3.4&quot; (such is the case in a couple of MI counties, and I'll bet it's not the only case). Also, a concealed weapon can be scissors, screwdriver, scratch awl, keyhole saw, and generally anything with a point or a blade. In Missouri you can mount a bayonet on your concealed weapon. CCW licenses from Missouri are honored/valid in Kansas. But if you cross the state line into KS, you MUST remove the bayonet off the weapon, or you'll get into trouble. Conclusion: don't carry this thing in the US, or better yet, don't get arrested with it.</p>
<p>I was thinking the exact same thing.<br>It can be construed as a concealed weapon.<br>&quot;Common Sense&quot; is useless as a defense in court if the authorities decide to make you a bad guy.</p>
Great idea!
<p>thank you TomC57</p>
<p>impressive craftsmanship !</p>
<p>thank you very much.</p>
<p>I would love to see a YouTube on this one.</p>
<p>Sure, i have documented this but not edited. i will post it after editing.(I also notify to you when i done) .</p><p>thanks for your motivating comment.</p>
<p>Hi,</p><p>You can try annealing the blade by heating it in an oven at 400 degrees F. for 30 minutes. Add a flashlight, flint and steel, with tinder. You can carry more of them in a pack, but if you loose all but your stick, you have blade, line, fire, and wrap some paracord around it as well!</p>
<p>I have never done heat treatment job, i have a small coal based furnace which i use for aluminium.</p><p> I will definitely try annealing. thanks for your valuable suggestions.</p>
<p>Really like this 'structable! Nice job!</p>
<p>Thanks for your appreciation. </p>
excellent job with this. im going to attempt to make one of these for my sons birthday. thanks for the upload.
<p>Thanks for appreciation, It will great to see your project pic, plz do share when you done. i also design a simple child safety lock for knife and 02 other function. i will share it in next instructable (currently working on it)</p>
<p>I love it! It is like a swiss army knife for survival.</p>
<p>big thanks for your comment, In next version of I will add a child safety lock and some more functions.</p>
