Now that the Company has come out with the ClipiTool Standard, it is my EDCBO (Every Day Carry Bottle Opener). Before that, I had the original ClipiTool bottle opener. In the interim, I managed to collect a few keychain bottle openers. Is anyone else a collector?
The black bottle opener on the far left is made of some sort of polymer. Don't remember how I got it but the small slot in front is to lift pull tabs, the cogs in the round opening are for twist off caps and the large slot in the middle is to pry off caps.
The next one is aluminum and was given to me by Tecate at a beer tasting and has a tab lifting tool as well as the bottle opener.
The third one from the left is a CRKT Snailor, the tiniest bottle opener I've found so far. You have to sort of nibble off the caps.
The black Gerber Shard attempts to be a multi-tool. The thing it does best is stab your tender parts.
The last one is a Kershaw that was a bonus when I ordered a knife. It does not work very well either.
But in all fairness, everyone of them will get the cap off of a bottle of beer, and that is what really matters.
Finally, here is a bottle opener sent to me by the Beer of the Month Club. The round opening had me scratching my head until I ran into a beer with a muselet, the wire cage that holds a fat cork on a bottle of beer, wine or champagne. Remove the wire and it does a superb job of prying out the cork.
