That is a good review of that model. He forgot only one thing I care about....... it fits nicely into the chest pocket of my bib overalls. Just perfect in fact.
I used one to do chores at the farm over the last year or so. Cutting baling twine when feeding big round bales to the cattle, cutting the tails off of Raccoons we harvested, as a scraper now and then, and an all around lightweight knife. I need to spend more time with it in starting fires, making feather sticks, and so forth.
A friend gave me my No. 8 and I am indebted to him for acquainting me with the brand. I also have a No. 10 found at a gunshow for $4 if I remember correctly. The 5 remains my favorite Opinel though.
