I've been using thier knives fr about 20 years now, and I love all the Opinels. A number 7 or 8 is usually my edc, with a filley knife in my pack for use as a food knife or fishing knife. I have the 5 inch fillet knife, and its never let me down. To keep the wood from swelling and making them hard to open, I use mineral oil in the joints, or sometimes I'll even take a paper match torn frm a book and smeer vasoline in the pivot area, and wipe out the exsess. A friend of mine who is from France told me to do that, and it works. You can even wash them out in a creek after that, and thier fine.
Opinels are one of the best knives around.
