I got this idea when I was fumbling around with exacto blades, screwdrivers, scissors etc...
Things you need,
Strong magnet(s) possibly from a hard-drive
Large heavy meatal object, I used a random steel bar
Some other tape
Step 1: Woo!
I decided to place a ring of hockey tape on the bottom of my steel bar, for stability, good looks and easy access.
This tape fits perfect.
Step 2: Magnets!
Put tape aroud your magnet(s) so it doesn't dull your blades or shatter.
Then place the magnet on top.
There is no need to tape it down at the moment, that is if the magnet is strong enough.
Step 3: Add Tools!
Just take you tools and make an arrangement that fits them so that you have easy access.
Here are my ideas.
Next, learn how to add even more tools.
Step 4: MORE TOOLS!
Try adding more metal to the organizer using the magnet, I added the braket from the hard-drive which holds the magnet, it has some holes for screwdrivers, and more surface area. You can try various other metal objects, I also used a wire egg holder which can hold tonnes of stuff.
Once you have a good accessory, tape everything down becuase the magnetic hold may become weak.
Then add more tools.
Now just pull a tool of to us it!
