I got my first O[pinel in 1982, and I've had what I admit to having a love/hate relationship with these knives ever since. I love how they slice and dice, and love how light they are for their size. I admit to being somewhat annoyed at times at how they are a needy knife with a fair amount of finagling and tinkering needed. I've had a dozen of them in various sizes, and gifted them off to people who needed a good knife, as I have gifted off dozens of Victorinox classics. I always keep an Opinel in the kitchen drawer for when I need a really really sharp knife, as well as one in the workshop out back. But…and I mean BUT in caps, I think I may be over them. It looks like they have changed/tweeked the design that didn't need any tweaking, and not for the better. They added a divot to the locking ring that lines up to a stamped/milled groove in the inner bolster that severely limits the travel of the outer locking ring. This means that the old trick of filing the top edge of the locking ring so it turns further around for a more secure lock, is negated. Done. Now impossible unless you now file down the protruding nub on the locking ring. What Opinel has done is actually sabotaging the lock, making slippage of the locking ring a real problem. I can only wonder why in Hades Opinel would weaken the design of the locking ring with this nub in a groove that limits how far the locking ring can be turned. Of course, some work with a half round file can eliminate it, but WHY?
