Introduction: Pocket Sized Grapple Gun

This grapple gun can be used for many things, from grabbing a paper off your friends desk, to getting a hat off a high shelf, this truly is the ultimate mini-tool.

Step 1: Materials

- 3 Standard Size Staples
- 1 Needle
- Thread
- 1 Black Paper-mate Ball Point Pen
- 1 Key-Chain Clip
- Low-Temp Hot Glue Gun
- Low-Temp Hot Glue Sticks
- Knife of Some Sort
Strongly Recommended
- Hack Saw or Dremel
- Empty Epoxy Putty Tube

Step 2: Saw Off Hook

Hold the key-chain clip in tour hand and saw off plastic hook, as seen in picture.

Step 3: Cut Piece of Pen

1)Pull out inside of pen

2)Measure pen against key-chain, pen peice should be about 3/16"-1/4" longer than clip piece.

3)Cut 2 pieces of ink barrel, one about 1" long and the other, about 1/4" long.

Step 4: Glue Together Pen Pieces

1)Hot glue 1" ink barrel piece to end of pen barrel piece.

2)Use needle to make sure there are no obstructions in the tube.

Step 5: Glue Pen Pieces to Clip

Glue the pen pieces to the clip and move trigger up and down a couple times to make sure it can move.

Step 6: Make the Grapple

1)Slide the smaller ink barrel piece onto the needle.

2)Pinch fingers just below ink barrel piece, position staples as evenly as possible, and apply a small bead of hot glue.

3)As a safety precaution I am required to tell you to put a bead of hot glue on the needle tip to dull it.

4)Cut a thread to the length of your desire(I recommend about 4 feet).

5)Tie the thread to the needle(at least a triple knot; very tight) and cut off the excess.

6)Tie the other end of the thread to the clip's bottom loop.

Step 7: Usage and Storage

1)Load the grappling hook into the barrel.

2)Make sure your hand is out of the way of the string.

3)Pull back the switch, and fire.

1)Wrap string around point where clip meets loop.

2)Put grappling hook through key ring, loop around ring, and put through key ring again.

3)Place it all in the empty epoxy putty tube.

Delo97 made it!(author)2011-04-17

Hmmmm, I think it would be better if you make it more "fishy":
-use a tri-pointed fish hook with glued needles
-use "fat" fishing line to make it more resistent

Delo97 made it!(author)2011-04-26

Hey, I've just discovered that "fat" fishing line has too much shape resistance for being shot whit this

chuperdrac made it!(author)2010-11-29

um, is it ok if i use it for a class science fair project?
my teacher said it doesn't have to be original.

evilkidjr made it!(author)2010-11-29

rubber+man made it!(author)2010-07-02

great job on desine but why do you put it in the epoxy putty tube?

evilkidjr made it!(author)2010-07-02

perfect sized holding containr so it doesnt catch on the inside of your pocket or can be used as a utility belt of super annoyingness to people sitting next to you

twonkie12 made it!(author)2010-02-20

You can buy hooks like the one in this "ible" at wal-mart for 97 cents. I got mine in automotive department by the keys.

ztaffa made it!(author)2010-02-20

how long should the needle be

evilkidjr made it!(author)2010-02-21

length does not really matter, what is howevrerfuegdfcujfd important is the width, try to give it just a little extra space in the pen tube

--swordy-- made it!(author)2010-02-08

this instructable is amazin i have made it and it dosnt even take that long

Robot+Lover made it!(author)2010-01-17

i also have that awesome mini hacksaw


try using one of those fishing hooks that have 3 points instead of staples theyd be much stronger :)

evilkidjr made it!(author)2009-08-30

originally that was the idea but i decided to make it with staples to make it something everyone can make

PastTheVoid made it!(author)2009-10-20

Well, everyone who lives near the coast could (should be able to) make it with a three-hooked fishing hook.

Alexxm1129 made it!(author)2009-10-08

Nice work!  I might make one!

platinum97 made it!(author)2009-08-27

Hey I have a question. Can u help me with an idea I don't have that keychain thing. So I just have a pen tape staples. And I want to make one with a button to press and it will launch the grapple. Can u help me?

evilkidjr made it!(author)2009-08-27

perhaps coil a paper clip like this /\/\/\_n_0 cut hole in pen, stick this part of pc
in pen hole, then use circular part of pc to hold grapplin hook then the other part of teh pc as a spring, to fire, press in bump

platinum97 made it!(author)2009-08-27

MadBricoleur made it!(author)2009-07-20

Cool!!! Wow, just so happens that I had one of those keychains already broken like that, but I threw it out while cleaning my room a few weeks ago... >:O 5 stars, faved, and voted for. Will you vote for me? :D

evilkidjr made it!(author)2009-07-20


MadBricoleur made it!(author)2009-07-20

and just an idea - what if you hooked up a grapple and taped around the end of the needle (easier - a toothpick) to fit inside a mini spud gun, then fire it out of there? more powerful, i would guess.

MadBricoleur made it!(author)2009-07-20

thx :D wow, talk about a quick reply. oh and btw, i just found out i didn't throw my keychain out!! bad news, the rod thing is cut all the way near the spring. i'll improvise, tho :D
