The Torpedo Bottle Opener.
A great addition to your key chain that will open thousands of bottles and still look like it did the day you purchased it. The overall length is right at 2.4" (60mm), and the width is just under 1/2" (10mm). These weigh in at 1 ounce (27.9 grams). The material is 316L Stainless Steel with a high gloss finish. As with all my products these are made to last a lifetime if not many lifetimes.
