Is this the same as a full-size bar blade?

No. It is a shortened paddle in the same speed-opener style. It opens caps the same way but has less length to lever with and takes up less space in a pocket or apron.

Will the vinyl grip hold up when wet?

That is the point of the coating. It gives traction on wet bottles and wet hands, which is why bartenders favor coated openers. Expect the coating to wear at the edges with heavy use.

Can it open crown caps on glass bottles?

Yes. The paddle lip hooks under a standard crown cap and lifts it. It is not made for corks, foil or can tabs.

How does 14 gauge steel compare with other openers?

14 gauge is thick stock for a handheld opener, so it resists bending when you lever a tight cap. Stamped sheet-metal openers are thinner and can flex.

Is it dishwasher safe?

Vinyl-coated openers are generally best hand washed. Heat and detergent can loosen or crack the coating, and moisture can get under it at the edges.

Bartenders and home hosts who open many bottles and want a durable, grippy opener that carries easily. Casual users who open a few bottles a month may prefer a smaller keychain opener.
