Picture of Swiss Army Fuse
This is a very simple Instructable based on my own experience of asking a tool to do more than it was designed to do.  MAKE SURE YOU READ THE LAST STEP THE WARNING!

Step 1: The Story

Picture of The Story
It was 1988.  I used to carry a single blade lock back hunting knife, but MacGyver was popular, so I had a mullet, wore acid washed jeans and started carrying a Swiss army knife.  (I was a teenager)  I had a 1983 Dodge Aries that was just reliable enough to get me to school and back.   One day I went to start my car and the only sound it made was a click and a pop.  I discovered that a fuse was blown, so I replaced it.  I tried to start the car and again,  just a click and a pop.  I kept putting in higher value fuses until I had blown every extra fuse I had.  I started looking around for something metal that I could use in place of a fuse.  I was looking for a paper clip, but all I could find was coins and old french fries.  I then thought of my Swiss army knife.  I opened up the scissors and compared them to the blades of the fuse. It was like it was designed not only for cutting paper, string, and hangnails, but also to be an emergency blade fuse!

I had a Victorinox.  I am not sure if Wenger or other brands would work.

better to take a fuse you do not need at that time, like internal lighting, seat or mirror warmers, enough choice out of the >50 in modern cars

Ok, I'll try to "be nice". This was very clever if you look at it from a purely mechanical standpoint: let's see, what do I have in my pocket that could bridge that gap in the fuse panel? A penny? A comb? Pocket lint? Wait! The scissors in my SAK! Damn, I'm clever.

This is the point to draw a distinction between clever and smart. Along the spectrum of unpredictable consequences from this kluge are some really expensive and/or dangerous ones. Because the author was lucky in this particular instance does not make it smart.

To be fair, we don't know the circumstances. If he was in the wrong part of town, or about to be swept away by a tsunami, or facing an overnight sleeping in the car in zero degree weather, ok, maybe. I'm glad it turned out ok for the author.

Thanks for being nice.

Good to know. I certainly hope I never find myself stranded and fuse-less with only Swiss Army scissors to save me, but I will be THRILLED to remember your project should that occasion arise.

Not a penny among those coins?
CHARLESCRANFORD (author)  chokapi2 years ago
Didn't think of that, at the time.
This is dangerous. You're lucky you didn't start a fire or cause the battery to explode and spray acid everywhere. Fuses pop for a reason - you should have found the shorted out battery terminal first rather than jamming scissors into a fusebox.
The battery would never have blown up.
A fire is unlikely, but smoke from burning wires was a possibility.
Anyway, you do what you have to to get home.

Could not have said it better VadimS. I got home.
Shorting lead-acid batteries does not make them explode, but it can burn/melt what you short hem with, which, if you don't know what is going on, can be confused with an explosion.

The author acknowledges the hazards, all you have to do is read what he writes before having an over-reaction.
