i always think about getting one, but the earlier models used a proprietary tool that i didnt want, and the newer ones i like are a bit too pricey imo. i like the idea of having a bottle opener and a decent blade in one spot, but ultimately i dont have much use for a 2.25" blade and i can use just about anything to open a beer when i have to (including an actual bottle opener), so i always talk myself out of it.
i guess id still consider trading for one or picking up a lightly used one- but i just cant justify it at retail price. that said, if your state laws limit your carry size or you happen to drink bottled beer away from home often enough, it seems totally worth a purchase
