Secret Boot Heel Grappling Hook

1.  8" of 1/8" steel tubing
2.  10' of 1/16m or 3/32 steel cable
3.  1/16 or 3/32 wire clamps
4.  Old pair of shoes

1.  Drill
2.  Dremmel
3.  Welder (MIG, ARC, TIG)
4.  Wire cutters

Other helpful tools
1.  Torch
2.  Vise

Step 1: Cutting

Mark and cut the 1/8" steel tubing into two four-inch pieces.

Step 2: Bending

I found that the easiest way to bend the tubing was to put the metal in a vise and heat it up as hot as I could.  Then, I was able to bend it into a hook shape.  Do that with both pieces.  

Using my MIG welder, I welded the two hooks together.

Step 3: Cutting

Taking the hook and one of the old shoes, I traced out the hook pattern on to the heel of the shoe.  After doing that, I put the shoe in my vice and drilled a 1/4" hole 3/4 of the way through the sole of the shoe.  This is the point where you begin to dremmel.  I dremmeled out a pattern in the shape of the hook into the heel of the shoe.  I then drilled a hole through the heel and into the inside of the shoe.  It is through this that the cable will go.  Once I had the hook well-embedded into the heel of the shoe, I had to glue a small magnet into the heel to secure it.

Step 4:

To store the cable, I decided to use an old sock and a piece of velcro.  I sewed a band of velcro on to the sock so that it formed a little velcro latch that holds the cable.
