Magnetic bottle opener

Picture of magnetic bottle opener
I happened upon a neat vintage-looking magnetic bottle opener in a high end store the other day and was amused on how simple the concept was and the price they were charging for it. I can't remember the brand of the exact opener I saw, but doing some research I found ones online for sale with prices ranging from $14 - $22. A little research reveals that the original design is by Brendan Ravenhill.

This magnetic bottle opener uses a bent nail to pry of the cap from your bottled beverage, and the magnet keeps the cap from flying away after opening. Another magnet on the side allows you to stick your opener on the fridge for easy access.

I'll show you how to make your own for less than $5 (possibly free if you have the materials on hand!). Not convinced you need one? You might think differently when you see how neat this opener is.

Here's what's I used to make mine:
  • saw
  • rotary tool (optional)
  • drill + bits
  • sandpaper (80 / 120 / 160 grit)    
  • indelible ink marker  
  • pencil
  • 2-part epoxy
  • scrap wood
  • 2-4 neodymium magnets
  • 2" nail with a large flanged head
  • stain:
    • tea
    • vinegar
    • steel wool
  • black spray paint
  • polyurethane spray sealant

Mikeasaurus, you pass the awesome test. I love the vintage look and the simplicity of this design, and I also appreciate the fact that you painstakingly list every step so noobs like me don't get lost. I will definitely be making this soon, and thank you for sharing.

Thanks for the cool idea, I attached 2 pictures showing how it turned out for me.

I used regular 18 mm magnets. Unfortunately the top magnet isn't strong enough to stick the bottle opener to the fridge. Maybe next time I should put 2 magnets over there.

To seal it, I used BEHR Polyurethane Satin Finish spray - 4 coats.

Wow, looks great Omer! I really like the grain of your wood.
Bummer about the magnet, but I think if you sunk another one in there that might do it.

Thanks for sharing, I've awarded you a 3-month Pro Membership and a digital patch for showing me your version.

Clever design, and thanks for sharing. I intend to use my scrollsaw to shape these. ;-)

I wondered what you were doing with that wood stain, very cool!

Well done!...
If you have a drimmel with a router attachment, you can create a much cleaner and tighter opening for your magnets. It would also allow you to control your depth much better.

I found the opposite. The drill bit I used is 9.8mm in diameter, allowing the 10mm magnets to snugly fir inside. By contrast, my rotary tool router bot is much smaller and the openings routed aren't as symmetrical. However, I don't have the steadiest hand :)

Why was I not updated about this- this is awesome! If only you had a way to instant freeze beer bottles, it would be every college freshman's dream party!

I heard another description of the look of this finish. . . "Early Pier One" 8^)

This bring me a lot of memories when I oppened a bar in my Garage. Oppened the beers bottles with one of these.

Pretty smart! A bit on the big side, but that can be an advantage as well (I keep losing bottle openeners...)
