Lasercut bottle openers


.


I am a fan of having a bottle opener on my bunch of keys, but am not a fan of large heavy bottle openers which weigh down my keys unnecessarily. I designed a bottle opener utilising CAD software and had it lasercut out of 2.5mm stainless steel. However, it was not as ergonomic as I had hoped. I have therefore designed several more ergonomic, interesting, and appealing beer openers. They too have been lasercut from 2.5mm stainless steel, and finished as follows. Deburred using a micro air grinder, and large grinding wheel. Thereafter, they have been polished on a polishing wheel to remove small shards of metal and create a slight edge round. Several have been intentionally left roughly ground, and several flamed. The flaming was done with a oxy-acetylene torch, heating the steel up to red-hot. Once the steel cools, it is left with different hues on the surface of the metal.

 I received the lasercut bottle openers from the factory and as you can see in the bottom right of the photo, there are four different types. They are as follows, from left to right... 'Long Thin One' ... 'Mark II' ... 'Fly Bird Fly' ... 'Sawblade'.

Deburring

Fettling / duburring of the profiles. Once this was completed the profiles were ground where needed on a large grinding wheel.

Process

The profile on the left is an unfinished profile. You can see the sharp edge. The second profile has been deburred with the micro die grinder, roughed up on the large grinding wheel, and polished on a polishing wheel to remove small shards of metal. The third and fourth profile have been flamed using an oxy-acetylene torch. This heats the metal up to red-hot, and as it cools, the surface of the steel becomes discoloured in hues from yellow, through to purple, then to blue. All the openers are stainless steel so will therefore not rust.

'Mark II'. This is the development from the first bottle opener I designed (Mark I) (2008)

Long Thin One

'Long Thin One'... with or without a twine grip. The grip can extend to just before the logo, or partly cover the logo.
