This is a Bento icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,300 icons, all in the same style and quality.
Icon "Bento" appears to kind of appear like an outline of a handgun or a boomerang. Two vertical lines that appear to look like chopstick are touching the edge of the gun. The attention of the object is drawn towards the top left corner. The design is very simplistic, and is not a very pleasing aesthetic. It looks like a draft for a better, full, and more attention grabbing logo. It is impossible to say what organization/idea/letter/alphabet the icon represents.
