opens bottles!
Size: One Size, Style: Bottle Opener
This bottle opener is very cool. It’s like a screwdriver, but it’s really a bottle opener! It has a grip to prevent your hand from flying off while opening a bottle. I also carry a bottle opener on my keychain and am always especially proud when someone needs a bottle opener and I have on right there on my keychain.

Great bottle opener
Size: One Size, Style: Bottle Opener
Love this bottle opener. Looks and feels just like the screwdriver. Easy to grip just like the hand tools. Good gift idea for the electrician or a diy person that appreciates quality tools.

Great bottle opener and looks cool too
Size: One Size, Style: Bottle Opener
Love this opener. Matches with all the other screwdrivers in my tool box and have it ready to whip open a beer whenever needed. Slips into the pocket to carry with you as well. Solid tool and I gave a couple buddies one as a gift. These will see many years of beer opening super fast.

Funny yet good bottle opener
Size: One Size, Style: Bottle Opener
Nice rubber grip. It would be better if the metal part was one inch longer, but still very functional.

The right tool for the job.
Size: One Size, Style: Bottle Opener, Size: One Size, Style: Bottle Opener
This is the tool you want. It is exceptionally functional, well made (made in the USA, if that matters to you), and beautiful in the way that quality tools are. The thing that really sets this tool apart is that it correctly balances form vs. function: a heavy duty build (as is the point when buying a bottle opener built by a tool company) without its use as a bottle opener (as is the point when buying ANY bottle opener) being negatively impacted by said build. I also bought the Craftsman bottle cap wrench, which, in my opinion, is hugely successful as feeling like a heavy duty tool and something of a failure as a bottle opener. It's so large and heavy, it has equal mass to the bottle you're opening. Imagine your buddy who has had one too many wielding a 12 oz. steel wrench over your tile floor, countertop, toes, etc. and you'll get the idea.
Lastly, the engraving and materials on this Klein tool are so attractive I had to build it a custom wall mount instead of hiding it away in a drawer or tool chest. I will be buying a second for the office.
