We all know the shame of struggling with that one stubborn bottle cap when you're swamped and opening three long necks, so feck that.

So I've bought a few off barblades.com (an english company) and they seem to lack "bite" if that makes sense? The best one is one that a guy I did a trial with gave me randomly, with two little sharp half ovals on the end of the "opening end" that really just tear off the caps. Reps in Ireland seem to lack in barblades, especially the ones who frequent my bar (it not really being a trendy place) so cant really get one from them

The majority of the ones I find online seem to either be just a rectangular opening or a very vague curve that can IMO leave you with a bent cap still on the bottle sometimes.

Any suggestions?

(bear in mind I am in Ireland but wouldnt be adverse to buying a decent few from an american site if it means paying a bit more. Cheers
