I’m glad they made these.
Size: One Size
Bought these because I work with Klein tools and for the typical “where did you get those?” Or basically an excuse to talk about how cool I am for owning these. Highly recommend.

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.
