I started this project because I wanted a more convenient way to carry and store the variety of 1/4" bits that I like to keep with me for my day to day tinkering.  Once I had something that served that purpose I thought it would be fun to try to pack in a bit more utility by adding on some features that I thought may be useful, or at least pretty cool to have on hand.  What I ended up with was a sort of DIY Pocket Tool that can be customized to meet your needs, that is simple and inexpensive to make.  Because I designed this tool to be customizable based on your personal needs this Instructable is not set up in the usual step by step fashion, instead each step will show you how to add a new tool/function to your DIY Pocket tool.

List of Functions that can potentially be added to the DIY Pocket Tool
  • Storage space for up to five 1/4" bits
  • 3' of utility cord
  • 2-3 strong 1/4" Magnets
  • Glass Breaker/Kobutan Self Defense Weapon
  • 1/4" Bit Driver
  • Xacto Knife
  • Storage for Xacto Knife Blades
  • Storage for Tweezers and Pins
  • 5" Rule
  • Pocket Clip
     
Note: All of these functions cannot be packed into one tool, for example storing Xacto Knife blades will take up space meaning you can store less 1/4" driver bits.  Also putting an Xacto Knife on one end and a glass breaker/kobutan on the other will make the inside of the tool inaccessible meaning that you will not be able to store anything inside the tool.  Pick and choose the functions that suite you and your needs best.


Materials
  • Aluminum Arrow  Shaft  -  This will become the body of the DIY Pocket tool and is where the 1/4" bits are stored. You can pick up damaged aluminum arrow shafts from your local archery pro-shop for free if you ask nicely.  One arrow shaft is enough to make 4 or 5 DIY Pocket Tools.  Aluminum arrows come in different diameters and weights so make sure the arrow shaft you select is big enough to fit your 1/4" bits or whatever else you plan to store inside.
  • Aluminum Arrow Tip Insert  -  This is what the tip of the arrow screws into.  If you get an old arrow to repurpose it will most likely already have this installed, if not you can buy tip inserts on websites like Amazon and Ebay very inexpensively.
  • 75 Grain Arrow Field Tip  -  This is the glass breaker/self defense part of the tool.  You can use any size field tip but I like the 75 grain tip for it's smaller profile and shape.
  • 3/8 Rubber End Cap This works as the cap that holds the 1/4" bits inside the body of the DIY Pocket Tool.
  • Pen or Pencil with Removable Pocket Clip  -   You want the type of clip that wraps the whole way around the pen or pencil, check out step 8 for an example.
  • Utility Cord - Similar to paracord, utility cord is a light weight cord that has extremely high tensile strength. Utility cord differs from paracord in that it is about 1 third as thick as paracord.
  • Xacto Knife - If you decide to make the DIY Pocket Tool with the Xacto blade holder you will be cutting and modifying an xacto knife to fit within the aluminum arrow shaft.
  • 3/8" Tubing (2" in length) - This will be used to creat the body of the bit driver component.
  • 1/4" bit driver - You'll be altering this piece so that it attaches to your DIY Pocket Tool in Step 3.
  • 1/4" rubber O ring - Used to affix the bit driver to the DIY Pocket Tool.
  • Various 1/4" Bits - Pick what would be most useful to you, for me personally I like to always have  T10 and T15 Torx bits because my car is held together with these types of screws.

Tools
  • Pipe/Tubing Cutter
  • Sand Paper
  • Drill Press or Hand Drill
  • Hack Saw
  • Sander
  • Super Glue/ Epoxy
  • Scissors
  • Lighter
  • Hammer
  • Needle Files
  • Pliers

Step 1: Cutting the Arrow Shaft

In this step you'll be cutting the arrow shaft to a length that fits comfortably in your pocket ( approx 5" long).

Tools Needed:
  • Ruler
  • Pipe Cutter
Materials Needed:
  • Aluminum Arrow Shaft.
Procedure:
You have a few things to decide before you start cutting.  The first thing you need to decide is if you want the glass breaker / self defense weapon (kobutan) as part of your tool.  If so, you need to cut your arrow shaft from the front of the arrow where the arrow tip insert is inserted.  If you plan to make your tool with the xacto knife insert then cut your arrow shaft so that both ends of the tube are open.

Either way cut your arrow shaft to an approximate length of 5" so that it fits comfortably in your pocket.

Once you have cut the arrow shaft, clean up any rough edges with either sand paper or files, paying special attention to remove any sharp burrs of metal.
I need this
i have alot of thick gauge dence wore left and i own a propane and coal forges i nake my lol ecacto lade out of lil rode i nake from the wire pund it super plat and filr a sharp edge (kinda looks like nini battle axe lol) the phillips head looks like a a bullet she...cool
Thanks for the idea. I modified your design and blueprints to fit my needs like a longer arrow shaft and bit driver.
<p>You had me at multifunctional!!</p>
This is AWESOME
AWESOME! I understand this is probably only a hobby, but with the way the survival market is blowing up I am sure you could secure your own enterprise if you got this thing on kick starter. Keep on building, and congrats on an amazing instructable.
<p>hi killRoy77,</p><p>That's a really cool idea! I've actually been toying around with the idea of doing something on kickstarter for some time and I think an upgraded version of this project would be a good idea. Thank you for your support!</p>
<p>Nice Leatherman Crunch</p>
Nice man, how about you make a survival kit pen, Check my survival pen for ideas. (If you like) xD
<p>Where does the screwdriver go?</p><p>By the way, great insructable!</p>
Hello Ouranos. the screw driver fits over the end that has the glass breaker or the xacto insert. the cuts in the top and the small black oring work to hold the screwdriver snug onto the tool. hope this helps!
<p>Thanks! </p>
This is awesome nice job with the attachment although I would use an air hose coupler male for on the shaft and female for the attachment
this is insanely awesome
Well done! High quality 'ible. I appreciated the creative photos, and well-designed tool. I am so going to try to make this one! Thanks for your work!
Your very welcome MiltReynolds, thank you for compliments and for enjoying my Instructable!
Great instructable Matt!<br>You could make things a lot easier with a lathe! It would mean you could cut the tubes to length really neatly and cut precise grooves for a ruler, maybe even with a millimetre scale! I was thinking you could cut the tube in half, add some tubing to the outside middle section (maybe a bigger arrow?) and cut some internal threads, then cut some threads on the outside of the smaller tube and make it thread together in the middle? (If that makes any sense!?) That would mean you could store things inside, but have the glass breaker and the X-acto knife!<br><br>I'm going to have to go and find some broken arrow shafts now! Thanks for such a great instructable!
Thank you very much jmcconnell5, I'm glad you enjoyed my Instructable. You're definately right that a metal lathe would make things both easier and more percises, (I've actually been meaning to track one down for my shop for some time.) Also, I totally understand what you're talking about with the tool breaking apart in the middle so that you have internal access as well as the ability to put tools on both ends, a very smart idea that I'll definately be testing out. Thanks for your post and your great comments and suggestions. <br>Best Regards, <br>Matt <br>
in looking this over and being a person who goes on survival trips I find it very useful. in fact I am constructing one this week, also gave me an idea for a few modifications as well. <br>Very good job <br>thanks
Thanks mmoberly3, I'm glad to hear that this has sparked the interest of a few survivalists out their like yourself. Please consider posting some pictures of your finished projects as I would enjoy seeing what modifications you come up with. <br>Best regards, <br>Matt
Really great little project, but I had to laugh when I saw &quot;your local archery pro-shop&quot;. Of course every small market town has one of those... I know there are other kinds of aluminium tube but they don't look as nice :/
I don't know what country you are in, but I think you would be surprised. The tiny town (pop. 2000) I grew up in had an archery shop within 10 minutes, outside of town. If deer hunting is done in your area, there is an archery shop around. You may not know where it is, but some searching should turn it up. <br> <br>Worst case, it doesn't, sporting goods stores, and even Walmart carry arrows. You might have to spend $3. <br> <br>Nice instructable, I will ask after damaged arrows at my daughters archery lessons next time I go!
Great points Glen! The same things are true for the area I live in, until I sparked an interest in archery I had no idea how many archery shops were in my area, (3 in a 20 mile radius!) And as Glen said you can always pick up arrows at big box stores like Walmart, Dicks sporting goods, Dunham's, etc. Also, thanks for the compliments; I&rsquo;m glad you enjoyed my Instructable!
Dude that is AMAZING, very well done.
im a 15 year old boy scout and i would find this project extremely helpful wheather im building projects or camping. <br>thanks for the great instructable.
You're very welcome quincy trott, I'm glad you like my Instructable. make sure to check back as I plan to update this project to add some additional features and uses.
Excellent ible' I must now make one
EXCELLENT 'Ible, well deserved feature status. Well done !
I thoroughly enjoyed this instructable
Thank you mayday12, I'm very glad that you enjoyed it. make sure to check back over the next few days as I will be adding a few more features based on some of the great comments and suggestions that have been made so far.
Great job. Great idea. And, very good explanation of your work and pictures
Matt, with a pair of these you would have an Ice Rescue Tool ! <br>http://www.rescuetech1.com/pick-of-lifeiceawls.aspx
That's a great idea dwebb5, I would have never thought of that but I really like it, Thanks!
This is really cool. <br>just thinking out loud here..... <br>from my understanding it doesn't seem like you can carry the exacto and the glass breaker at the same time? and both the bits and the tweezers wont fit in the tube at the same time? <br>I wonder if you could have screw inserts on both ends of the shaft. have the arrow head glass breaker on one end and the exacto on the other. can both the bits and the exacto blades fit in the shaff? maybe lengthen the shaft a little so you can get the blades out from one end and the bits from the other. the magnet you could put in the bit driver tube. this would also add the function that the magnet would hold the screws on the bit. the magnet would also hold the bit driver in place when slid over the tube. <br>I also think you can probably store the tweezers under the braided cord. <br> <br>really nice job, great pictures and explanations.
Hello Dimtick, <br>First off let me say thank you for your compliments and for your great thoughts and suggestions. You're correct that equipping the DIY Pocket Tool with the Xacto Knife and Glass Breaker will seal off the tool meaning that you can't carry any bits or other accessories inside. I like the Idea of screw-in inserts but you would have to use a thicker tubing to accommodate cutting in threads (definitely worth trying though as using a thicker tubing wouldn't be that big of an issue other than the negligible weight increase) As for bits and Xacto blades, yes you can carry them together, you just have to sacrifice storage space for one or two bits (and you should store your blades at the top of the tool in such a way that the bottoms of the Xacto blades sit on the bit underneath them so that they blades don't get beat up by being repeated jostled against the steel bits.) <br> <br>Thanks again,one of the things I like best about writing Instructables is getting to share thoughts and ideas with interesting people such as yourself. <br>Best Regards!
Great documentation! Faved! :) Voted! :)
ok i didna look at all yr steps then.
here u might want to dril a hole 4 yr arrow shaft. so u can use it as a T - handle, as well as a straight handle.
u might wanna grind off a small area on both side . soo u can get a wrench on there to take off that head. in case u need to swap it out 4 a different head.
Cool ideas. Looks like you gave me another project to work on.
Great documentation
Great instrctable. I think that you have a great inventive mind. I think other great pocket tools started out this same way to become a commercial success, good job. One caveat with any tool like this carried in public, especially in the USA unfortunately, police could &quot;consider&quot; a tool like this to either be a &quot;burglary tool&quot; or a concealed &quot;deadly weapon&quot;. Please be careful when carrying anything on your person in public, know your local laws and know and stand up for your rights.
Thanks for your compliments Bob3030 and thanks for bringing up those important points about safety!
Great work! Thanks for sharing this with us - you did a great job documenting your build.
Thanks Audreyobscura, that's a very nice compliment!
Wow! Leatherman USA needs to hire you right away. I'm an instructables junkie and yours is one of the top 5 I've had the pleasure to see. I have a bunch of aluminum arrows and never considered them for any kind of hack. Great job!
Wow back at ya Coptician, thank you very much for your fantastic compliments! It would certainly be a lot of fun to work for Leatherman, I think they're a great company! I'm in the same boat as you I have a bunch of worn out aluminum arrows and am constantly inventing new uses for them. <br>Thanks for awarding me a spot in your top 5! <br>Best Regards, <br>Matt
Very cool!
Thank you M3G!
