OPERATION: With the BOJ wall-mounted corkscrew is very easy to open wine bottles with efficiency. The leverage arm of this opener measures 12 inches to maximize extracting power, with an overall height of 22 inches. Place the bottle in the holder: it is not necessary to hold the bottle. The wall–mounted corkscrew is very sturdy and the mechanism works smoothly. USAGE: Primarily designed for places with a high volume of openings like restaurants, wineries, bars, wine-tasting rooms, or catering. However, customers tend to purchase it to give a professional touch to home bars or enhance beautiful kitchens. Unique as a personal or corporate gift. MATERIALS: Both the handle and backing are made of sapele, a large tree native to tropical Africa, also known as aboudikro. Some luxury car manufacturers use the same wood for their high-end vehicles. The body is mostly made of zamak, a resistant material with a base metal of zinc and alloying elements. The worm is a strong-milled spiral made of steel. All necessary mounting screws are included. WORLDWIDE PATENT: The wall mount corkscrew was originally designed 75 years ago by Santiago Olaneta, son of the founder, and his design team. Improved with the feedback of thousands of thousands of hours of operation from customers. MADE IN HOUSE: In Spain for decades. BOJ, a third-generation family-owned company in the north of Spain, has designed and manufactured unique wine tools in the same workshop since 1905.
