The link shows non-locking Opinels no 2-5.No2 to No5 ???
No 6 is made for children.
No 7 exists for children with a round tip.
Your link shows jokes, no tools.
I wouldn’t use an Opinel for bushcraft but why would you take off the locking ring? It’s fine because it’s being used with good reason. Removing the lock doesn’t make it legal for EDC here, but it does make it a lot more dangerous.The knife I recommend to adult Germans for Bushcraft is the Opinel No8. The handle has the weil fitting Size.
The Opinel No7 Carbone is OK for hiking and bushcraft too. It costs 9,20€.
It has a 8cm blade. If you shorten it 3,8 mm you make it UK legal.
That is possible with a normal file and a simple sharpening stone.
The Opinel No6 has the right handle size for 6 years old children. It is made for CHILDREN.
The No 7 is made for young people and women, but a lot of men prefere it too, because it fits a bit better in the pocket.
As I wrote, the sizes smaller than No6 are jokes, no tools.
But buy what you like, no problem!
The pointy tip is useful when using it to pierce the lid of tin cans, you can then open them.One thing I do not like with the Opinel is the very pointy tip.
It is a weak point. Although I never, ever baton, I have broken many tips off Carbon knives.
It will not lessen the usefulness much, but it is irritating.
I think it is a combination of things:I have allways hard to understand why scouts of today is so focused on the less safe folding knives insteed of using a fixed knife. A small victorinox or multitool i can understand but with anything for carving, ropework, food prep etc my first pick is a fixed blade knife. For those with smaller hand a Mora carving knife junior is perfect as a starter knife. For somewhat older kids they can learn to oil a handle and/or stain it as part of the knife training.
