I WOULD call Opinel knives cheap! They are cheap to buy and they are cheaply made. The only thing is that as cheaply made they are - they are still well made and they work well. The person that designed them was freakin' brilliant IMO. To design something so simple and cheap to make, but would last well with normal use and easily sharpen to an incredible scary sharpness - that is genius!
The Opinel knives are not made with CPM S30V steel or carbon fibre anything or titanium anything or any type of resin or glass. They are cheap simple knives made from cheap simple materials, they cost little to make and they can be sold in huge numbers at a low price. They are the ultimate affordable folding knife that anyone can own! The locking mechanism is the cheapest I've seen, but it works!
I have a #4, #6 & #9 all in beech wood and carbon steel. All feel cheap and yet they are all VERY capable knives. They are light and cheap and simple, but boy will they slice a tomato easily! I like the design so much that I have ordered a luxury model - a #8 with a walnut handle and a stainless steel blade, yet still under twelve bucks!
There is a hell of a difference between a cheaply made and cheaply priced product VS a crapily made piece of junk that is cheaply priced. Anyone can cut corners and produce junk, but Opinel has just kept the design cheap and simple - NOT junk!
