I can. I give you the HP 12C financial calculator. First made is 1981 and still in production and in demand.
Financial guys still use these all the time. And I am useless w/o mine. http://sliderule.mraiow.com/wiki/Hewlett_Packard_HP-12C The HP-12C financial calculator was introduced in 1981, and is the only one of the popular Voyager series of calculators to stand the test of time. Currently there are three major variations of this calculator, including the HP-12C Platinum and the HP-12C Platinum 25th Anniversary Edition. The 12C is the only purely RPN calculator still sold by HP; the other calculators that support RPN also support semialgebraic entry as an optional setting. Financial stuff baffles me. How can someone take the wonderful set of mathematical knowledge we humans derived over the last 4000 years and make these weird compound interest and sinking fund thingies is beyond me. I'm sure no good will come of it. Money is the root of all evil, after all. Anyway, for the times I get confused, there is a nice little cheat-sheet on the reverse side. Low-power design permits the calculator to go 6-12 months between changes of standard, store-bought, button batteries. No more worrying about replacing that darned custom battery pack! |

A billy club––you can't beat a good piece of hickory. Simple, yet remarkably elegant.

The wheel still seems pretty popular.
The .30-06 Springfield is also able to get the job done, despite new-fangled whiz-bangery. |
|
The wristwatch?
Everything from manual watches to the Casio G-shock. They've stood the test of time so well, that many many of them are re-issued or cloned or recreated in some fashion. I can't really think of anything more significant than timepieces. |

1. M-2 .50 cal.
2. Also, despite numerous prophesies on the contrary, the internal combustion engine. 3. The wheel. |

Revolving cylinder handgun. In production since the mid 1830's and still in demand.

The bucks computer!!! I joined the Army back in 1989 as a field artillery surveyor and that little calculator right there was standard issue, LOL!
ETA: the pimp hand has stood the test of time. |

Quoted:
... LOVE OF Money is the root of all evil, after all. .. At least get the quote right. Tech that is still in use? Light bulbs.. Steel. Bows ares still used for hunting 1000's of years after their invention. |

light bulb. 150 years and not much difference in an incandescent light.

Lockheed C-130 Hercules

Quoted:

HP 12C financial calculator?? Can't you use a pencil and paper to do the same thing? I was gonna say, the wheel. Also, the slide rule was used to create the SR-71 Blackbird. |
|
The shovel and hammer. There are faster and easier things to dig holes and drive nails with but those two will be around forever.
|
|
Technology? The pencil.
Think about it. Invention? The light bulb. Imagine the world without artificial light. |

Solving for i is a bitch w/ a pencil and paper. And I should have been more clear. Originally, I was going to say electronics instead of technology, but I didn't want to the thread to go straight to sex toys. Still, good examples. |

hammer, shovel, knife
the whacker, the digger, the cutter.... all other tools (including the plow) come from these, and they're still in use today |

Quoted: The nail. Posted Via AR15.Com Mobile The hammer is older. You needed a hammer to make a nail. |
