Nov 06, 2013 Opinel Knives Simplicity is bliss. I've always been a firm believer in this statement and try to apply it to every aspect of my life. Shoes, boots, bicycles, the leather goods I build, and the tools I use all seem to work better, last longer, and generally age with grace the more simply they've been built. Opinel knives are no exception. For more than 120 years Opinel has been hand building knives in France using high quality carbon steels and a simple wooden handle. Incredibly well made and built for a lifetime of use.
