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

Step 1: cut wood + bend nail

For the bottle opener handle I used some scrap 1-1/16" x 1-1/16"  (roughly 27mm x 27mm) SPF rail cut into about a 3" (7.5cm) length.
On one end of the handle draw diagonal lines from each corner, where the lines intersect will be the centre of the cross section. This is where the nail will be placed.

My nail was about 4mm thick so I used a 5/32" bit (4mm) and drilled into the line intersection on the handle end, boring about 1.5" (40mm) deep.

Using a capped bottle as a guide the nail was positioned where the flanged nail end met with the edge of the cap lip, a mark was made where the nail met the drilled opening in the wood handle.

With two vise pliers, the nail was bent in a 90° angle at the mark. Any scuff marks made during bending will be covered in paint later.
<p>I decided to leave the nail bare on mine because I liked the look of the rust. </p>
<p>Looks great. The rusty ail goes really well with the dark stain. Thanks for sharing, M3G!</p>
<p>Thanks for posting this Mikeasaurus! I loved doing this project myself and will do a few more now that people have seen it and want one for their own. Below is my first attempt I did for my dad for a Father's Day gift. I ended up making mine a bit more bulky with a total length of 5'' instead of 3''. The stain is in the color &quot;kona&quot;, two coats and sanding afterward. I applied a pretty heavy Cabot varnish to add some durability too. </p>
<p>Whoa, looks great!</p><p>Thanks for sharing, enjoy the patch and 3-month Pro</p>
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.<br> <br> 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.<br> <br> To seal it, I used BEHR Polyurethane Satin Finish spray - 4 coats.
Wow, looks great Omer! I really like the grain of your wood. <br />Bummer about the magnet, but I think if you sunk another one in there that might do it. <br /> <br />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!
This is not a new idea, nor was it invented by Brendan Ravenhill. <br>If you actually look around, you will see this design has been around a few decades, probably more. Even cursory research (maybe 15 seconds of my time) reveals a very common Pop Mechanics version from 1966
Well done!... <br>
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...)
Simple and amazing!!! Thanks for sharing!
