Etsy seller Boonerings has taken the same idea as the tradtional Swiss knives, and has implemented it in a simple titanium ring. Available in a range of different sizes, this small but fully functional offers five different essential instruments: a bottle opener, a comb, a slate blade, a saw, and a serrated blade. Brass rivets hold the plates together.
Apart from this convenient tool, this ring is very comfortable and adds a classy look to its owner, with the option of engraving it if desired.
Although the concept of this ring may be off-putting or considered a gimmick because of its small size yet large utility, this ring is a fine, carefully engineered and artisanal product. It is not solemnly a piece of jewelry that intends to look classic and professional, but it is a completely functional and helpful piece for daily tasks and activities.
