Introduction: $6 Slapjack/sap
I have always liked Black Jacks, Saps and any other impact devices. They make me thing of Boston Blackie, the untouchables and all those old mob movies! But they aren't only fun to watch on TV they also are a viable option for self defense today. Although I am not suggesting to use this for self defense. And it's a good idea to look up your state and local laws before making or carrying one of these. That being said in this instructable I am going to go step by step on how to make a slap Jack for $6 or less!
11 feet of 3/8" rope (or what ever size you like)
Two Tire weights (or other heavy objects)
Pair of pliers or vise grips
Neetle nosed pliers
Step 1: Measuring and Cutting Rope
To make the black jack first I cut 11 feet of our rope then melt the ends so they don't unravel.
Step 2: Weights
Next I take two long tire weights and pull the steel clips out of them so they will lay flat. (You can use any thing you want to for a weight I just had tire weights laying around and they worked very well.) Because my tire weights are old and probably made from lead i wrapped them in electric tap to seal them off.
Step 3: Making the Body
Next I take the the 11 feet of rope and fold it in half then go up from the loop end 15 inches. Next I use the cobra knot and start to braid two rows towards the loop end. ( if you don't know how to do the cobra knot there are some great tutorials on instructables and YouTube also the picture above give a idea how to tie the cobra knot. Step 1 make a loop by laying end across the body Step 2 take opposite end and go over the first end Step 3 go under body and up thru loop pull tight and alternate instructions each time.)
Step 4: Adding Weights
Then I take the lead weights and stick the end under the two layers of braid one on top one on the bottom then I use electric tape to keep them from moving.
Step 5: Finishing Up
Then I simply braid over the weights and continue wrapping the body until I can just manage to comfortably slip my hand in the loop for a lanyard. To finish up I cut off and melt the ends. My Black Jack ended up to be 9" not including loop. And there you have it a DIY black jack for less than $6 that will last a long time!
