Ninja Climbing Claws, Shuko

In this instructable you will learn how to make your own set of shuko, or ninja climbing claws. these can be dangerous because they have nails in them, so please use them only for climbing. it took me a while to think up this design even though I've been thinking about making it for a while.

the materials you will need will be:

1. velcro
2. webbing with a buckle on it (see picture 2 for type of buckle.)
3. wood (I used 3/4 inch plywood but thinner would work.)
4. large-ish nails (size depends on your preference, but don't go too small.)

tools you need will be

1. staple gun
2. jigsaw
3. hammer
4.pencil
5. pliers
6. scissors
7. matches

note: you do not have to use these exact tools, but this makes it faster and it is what I used. Example: you could use a normal hand saw instead of a jigsaw and you could use leather instead of webbing, but you would need to find a good working buckle.

pic 4 is the type of buckle you need.

Step 1:

In this step you will be marking and cutting the main body of the claw.

get your plywood and mark 1 5/8 in. by 2 5/8 in. with your pencil. for you it may be smaller or larger, but it must fit well it the upper palm of your hand right before the bottoms of your fingers on the ridge. (pic 1)

cut it out with your jigsaw. (pic 2)

mark five dots on the upper middle part of your cut out piece. this is where the nails will go. try to make to dots equally spaced even though it's not critical. (pic 3)

Step 2:

This step will be about putting in the nails.

Take your first nail and line it up on the first mark on the wood. before you hammer it in, place the marked piece on another piece of wood for the nail to go into. (see pic 2) Now hammer the nail in. don't put it in very far, just about as much as in pic 3.

put in all nails in the same way.

Step 3:

this step will teach you how to secure the nails in place on the main body and bend them down.

First, take your pliers and bend the part of the nail with the flat part down towards the back of the body. then hammer the nail into the body so the flat part bites into the bottom of the back of the body (see pic. 1, 2, and 3) this will lock the nails in place.

then, you have to bend the front of the nails down about 40 degrees. (pics. 4, 5, and 6)

repeat on all other nails.

Step 4:

In this step, you will learn how to put the bottom part of the webbing onto the main body.

the longer piece of webbing is 16 1/2 in. the smaller on is 3 1/2 in. not including the buckle which is on the shorter half. remember to burn the cut end of webbing with your matches.

if this is for you right hand, put the long strap on the left side, and if it is your left hand, the longer one goes on the right.

look at pictures for placing of straps and where to staple the straps on. do not staple on the nails. make sure that the buckle is upside down so when you turn over the body the buckle is rightside up. cut off the label which should be facing you.

Step 5:

this step is about attaching the top webbing.

cut a 9 1/2 inch piece of webbing. remember to burn the ends.

about a half inch from the bottom of the webbing stick the far right nails through it (pic 1) and staple it as close to the nails as possible on both sides of the nails.

put a piece of velcro on the underside of the end of the strap. (pic 3) and then put a piece of velcro on the bottom of the body overlapping the webbing. (pic 2)

pic 4 is for overall reference.

put the webbing on the right for a right handed claw.

Step 6:

this will be an easy step just about attaching velcro. 

put the first strip of velcro 4 1/2 to 6 inches from the edge of the body on the bottom right strap. 

put the other one on the end of the strap.

your done! now to put it on.

Step 7:

here is how to put it on.

Step 8:

thank you for making my claws and I hope you vote for them in the contests. 
I really want a 3d printer so if you vote for me in that contest 
I will make another instructable on ashuko, foot claws and a secret weapon I designed myself. 
goddbye.
