I feel about Opinels the same way I feel about Moras: they're a fine gateway and a neat piece, but anyone who says they perform better than a good quality knife by a reputable maker using modern steels and materials is lying to themselves. Like a Mora it's a great value, maybe even the best value... but best quality? Really?
IMO, discussions of quality are always second place to discussions of design. I don't care how high quality a sports car is when I need to drive on a logging road.
There are 3 aspects of the Opinel's design that have real merit: the blade geometry, the blade steel and the joint/handle design.
IMO, the geometry of the Opinel makes it among the most versatile that I've used. It's thin enough to slice well and the slight convex grind allows it work wood better than any full flat grind knife that I've used. Someday, some manufacturer of more expensive modern knives is going to knock off the Opinel grind (and tout it as an R&D success - where R&D means rip-off and duplicate) but until that day, if you want this great blade geometry, you need to buy an Opinel.
With respect to blade steels... there is a never ending and insoluble argument here between fans of fine carbide steels and fans of modern carbide rich steels. I won't try to win that argument or change any minds on that topic. Suffice it to say that there are a large number of knife manufacturers committed to fine carbide steels and huge numbers of people who prefer blades with fine grained steels over those with carbides. Toughness and ease of sharpening, or at least perceptions of these, are often quoted as reasons. Again, I'm not arguing this one way or the other. While some may argue that all knife users should prefer more expensive carbide rich steels, the reality is that many people, including people who have money to spend and knowledge and experience with steels prefer fine carbide steels. This is a design preference and it trumps "quality" comparisons to other types of carbide rich steels. The point here is that when you compare Opinel's Sandvik 12C27 other other fine grained steels, it's very, very hard to find a better fine carbide steel.
With respect to the lock, joint and handle design and noting that hte lock is NOT designed to prevent the blade from closing, the simple joint is incredibly durable with respect to hard cutting and hard lateral forces. It's rare to find an Opinel that's been damaged to the point of having meaningful blade play or wobble, much less to break the joint. The joint also stands up better than most designs to being fouled with dirt and sand. And the handle's design has stood the test of time and generally gives many hands a good grip with a minimum of hot spots (and what hot spots exist for an individual can be easily sanded off). Lastly, the design is very light weight. Combined, the design (not the build quality and not hte material quality) make it a very durable and comfortable hard use working knife that weighs very, very little.
Taken together, just on the basis of design (not quality), the Opinel is a hard knife to beat.
Can you suggest a modern alternative that
- has the same or similar geometry
- is as durable and robust at the joint
- is as comfortable in hand
- is as light
