Used for climbing and scaling trees. Hooks can dig into the bark and strengthen your grip. I'm sure these were also used in fighting to strip enemies of their weapons or even to just injure them with the sharp spikes.


This wasn't a last minute thing, in a way I take my hobbies very seriously. I'm very picky on what materials I plan to use. A lot of thought went into this project to make the materials as durable as possible, cost effective, and functional.


Completion Time

1 - 2 hours depending on how many tape layers you apply

* at least 24 for the J-B weld to harden *


Cost

Depends on what you already have at your disposal

If you have no materials , but honestly I'm sure every home has a roll of duct tape

J-B Weld                         $ 4.00
Hooks   .25 x 6 =             $  1.50
Miscellaneous Metal        $  ?.??

Rough Estimate Price Range  $6 - $8 

Step 1: Materials List / Tools Needed


Materials List:
    
    *   Duct Tape
    *   1 in.  Metal Plate Cut to Palm Width
    *   Hook and Eyes # 8 Screw Hooks
    *   J-B Weld
    *   Paracord
    *   Hot Glue

Tools Needed:

    * Dremel Tool
          - Metal Cutting Attachment
          - Grinding Stone Attachment
    * Hot Glue Gun

Step 2: Measure and Cut the Metal Plate


First step is cutting the 1 inch metal plate similar to the size of your palm. Use the Metal cutting attachment and the Dremel for this step. Use a sharpie and ruler to draw a straight line onto the metal plate. Use this as a guide when using the Dremel tool to get the best results.

Step 3: Cut Screw Hooks to Size


Second use the Dremel cutting attachment to modify the hooks as seen in the picture below. The angle is and estimate, your trying to add a point to the end of your hooks. Shorten the end of the hook by completely cutting of the screw portion of the hook.


 * Use the picture as a guide, cut where the red lines intersect the Screw hook. The above image is the finished hook spike.

Step 4: J-B Weld Hooks to Metal Plate

Use a ruler and pencil to make the markings as shown. They are 2 inches apart. 

Next mix equal portions of the J-B weld and apply it to the hook as shown in the 2nd picture.

Place the modified hooks on the lines as shown and secure them using duct tape. Try to keep the hooks as straight as possible. Let the J-B Weld dry over night, also be sure to periodically check the hooks within the first few hours to be sure that they don't shift. Once the J-B Weld has hardened its almost impossible to correct any mistakes so be careful

Step 5: Duct Taping Process

Basically Duct tape is very self explanatory. 

1 ) Start off with just a thin band of tape going around your palm and the dried Hooks and Metal Plat ( The Rig )

2) Then take more thin bands and wrap around The Rig vertically. Be sure to reinforce this very well, it ill be one of the most important parts.

3). Estimate the distance from the 2 middle gaps to your wrist, Cut 2 thin strips of tape double that length and add 1 inch to that length. The extra inch will be used to secure the Paracord. Reinforce with multiple layers of tape.

4) Reinforce those 2 strand  with normal width pieces to fill in the gap.

5) Next refer to the pictures to see how to attach the paracord, fairly simple, like rolling a tube of toothpaste :D

6) Apply 1 last final full width strip to the entire length (from wrist to the top of The Rig)

Step 6: Finished Product

Finished product, if you have any questions feel free to ask. Critics, feel free as well.


Leave a comment and tell me what you think. If you liked the idea but did something different please let me know, I like to learn :)


If you enjoy this instructable and other gadgets, I'd really appreciate if you'd visit my

All feedback is greatly appreciated. Leave a "thumbs down" if that's what you think. I enjoy constructive criticism but please leave a comment explaining why so I can learn from building flaws.

I wish good luck to everybody else entering the contest, and thank you for your consideration. I put a lot of thought into the materials list to make this as solid as possible, so I'd greatly appreciate your vote.


VOTE FOR ME IF YOU THINK NINJAS ARE AWESOME :P


it looks like the string will snap your wrist off
<p>Ninjas use these with their hands. Back then they had to climb palace walls. These grip on to tiny cracks and such.</p>
What have you climbed with these
<p>Wow you are on instructables as well</p>
<p>Ninjas got my vote</p>
This is just a prop right? u don't expect it to really hold u right?
U will fall
im currently building a pair out of weight lifting gloves (leather, fingerless). question, have you strenght tested the jb weld?<br>if so please re comment with results
Awesome.<br>I've been looking for a way to make those for quite a long time, I think I'm going to base my project on yours.<br><br>Thanks, Mike.
going to make one of thise!! will be fun climbing trees:P
How does it not slip up and off your fingers? I mean... does that string actually hold it on well even though you put your whole body weight on it?
I'm not gonna lie its not the most comfortable thing to wear, but that string is 550 Paracord. Its the stuff people use to suspend themselves from their parachute and it's suppose to withstand 550 lbs of weight. I weigh around 180 lbs and this worked for me. Also, you wouldn't be putting your whole body weight just on the gloves. Unless you have amazing upper body strength your still going to have to use your legs when climbing.<br> <br> Here's a link to some pictures of the real thing<br> <br> <a>. http://www.google.com/images?hl=en&amp;expIds=17259,27434,27743,27788,27797&amp;sugexp=leprodeca4&amp;xhr=t&amp;q=ninja+hand+claws&amp;cp=12&amp;um=1&amp;ie=UTF-8&amp;source=og&amp;sa=N&amp;tab=wi&amp;biw=1680&amp;bih=880</a><br>
Ah yes, I know what the real thing is. I didn't realize &quot;550&quot; meant 550 pounds.<br>I think I was more concerned about the string untying or something?
Yes, &quot;550&quot; should represent the minimum breaking strength of that type of paracord; however, I understand there to be a lot of cheap cordage out there.<br><br>Using webbing instead would make the claws even more comfortable. Cool idea, by the way!
Aside from being EXTREMELY painful to have a substantial amount of weight on such a small area of your body.
I'm going to make some of these for myself and some freinds, I was thinking of arc welding the hooks on and making some sort of fingerless glove to exert the pressure to different parts of the hand.
Hey instead of using J-B weld (i dont have any) could you use Krazy Glue or Gorilla Glue? *-*
I actually came up with this concept about a month ago. It's nice you beat me to it though. Great minds think alike i suppose. My idea would have more of a horizontal handle though, made from some kind of angled gardening tool with sharpened points and support straps maybe. I might make it and post it sometime. (I'll credit you for the idea if i do.) Otherwise, a quite clear and informative instructable, I must congradulate you on that. Good Day.
Seems like this won't help you climb, but just make it easy to hurt your hands.
do they work?
Yes they do, I'm planning on remaking them more sturdy with maybe old leather belts as the straps. I was going to enter it into one of the contest but missed the deadline. Oh well.
Very well documented, nice pictures too.
Have you tried them out yet?
Yea, they work pretty good. I was able to climb some trees in my back yard woods no problem. I'm an experienced climber but I could definably feel more grip and traction while wearing the hand claws.
Nice, I'll have to try making some. (Once the winter season is over...)
Hah, yea. Well if you do take a pic and post it here. I'd love to see how your comes out.
