that depends on how you use a knife, a opinel is a good knife, but not that world most strongest one. i personally use mine opinel as back-up folding knife, some wood cutting and the light but dirty jobs (opinels are cheap ).
a S&W would be more suitable i think, i bought mine a S&W cutting horse 4.6 inch tanto blade for €20. they are one hand openialbe, has a nice beltclip and a lanyard holl. great stuff for the price.
