A simple little folding knife by Opinel of France. What it might lack in bells and whistles it makes up in spirit and functionality. I've used a no.9 for some years having purchased it when I was living on an organic farm in Brittany. It was my main knife during my stay there and I really loved it. light weight and razor sharp ideal for simple wood carving, kitchen use and general cutting tasks. The stainless steel collar and nice wooden handle gives the knife an almost respectable, gentleman like appearance. Later, my wife bought the no.8 and loved it! To be honest I prefer the no.8 for it's smaller size. Most of my fixed blade knives are around nine inches in length which is an ideal size for a main knife however for a back up folding knife I prefer a smaller size. It's much more comfortable when using it in the kitchen and when using it for small tasks.
These little knives retail in around €10 to €15. If your in France you can get them a bit cheaper. The more specialised models can go for much higher prices and in general the higher up the numbers you go which means the bigger the size, the price follows too.
Carbon steel knives tend to be a bit cheaper than the stainless steel ones. Personally I prefer carbon steel as it holds its edge better and is easier to sharpen. Plus I just love how it develops its own natural rust protection (patina).
I really can't say anything bad about these knives. They're just so versatile in their design. All in all this is an excellent folding knife for the price. It really is a great knife for just about everything.
