Great Knuckleduster From a Wind Up Key.

Or a giant wing nut.

Ok so this i'ble is on a handmade knuckleduster that
doesn't look like one when the coppas get you.

Now i find this more comfortable and effective than
regular "knucks" and a whole lot more comfortable too.

What you need

Giant wing nut and bolt or big windd up key
(size shown in pic)

Gorilla glue

Fake (or real) leather scrap.

Put the scrap lengthwise and fold over top. (first pic)

Fold The bottom up (second pic)

Once you have done that to try out get the gorilla glue and wipe
it over it than fold as in first parts of this step.

Once the glue is on get some nylon or other string and wrap
around the wing nut (or wind up key) at all the curves)

After a while it will stop being sticky and you can test
it out.

Use for whatever you want within the perimeters of the law
or just keep in your pocket to feel safe.

You can varnish or buff it if you want but anyway ENJOY!
