Opinel Carbon Steel No.4 Non-Locking

Opinel Carbon Steel No.4 Non-Locking



Opinel knife blades are made using steels with a high carbon content, which is what makes it possible to achieve the excellent hardness after heat treatment, guaranteeing the good strength of the cutting edge, resistance to wear and easy sharpening. The handles are made from durable French orange beech wood, and the Opinel Yatagan blades, with their curved points and round profiles, are effective, precise and elegant. These small non locking Opinel knives have blades under 3 inches and therefore legal to carry in the UK.

  1. Opinel No5 Carbon Review by
    This is my first Opinel and i was a little surprised just how light weight it is . Ok its only a number 5 but i have knives of a similar size that are much heavier . The blade is thin but very sharp out of the "Bag" ,(it doesn,t come in a box ) , ideal for opening mail etc but nothing to heavy . Glad to have an Opinel in my collection but not sure i will buy another .A bit of rustic France . (Posted on )
  2. Opinel No.2, 3.5cm.Review by
    Good little micro knife. Nice little backup for when you can't whip out a knife that people may deem "scary". No complaints. (Posted on )
  3. No worries. Review by
    "Sacrificial" is a fitting term for the Opinel No 4. That is, if a task seems likely to damage the blade, this little trooper steps bravely forward. Saving that posh expensive slipjoint in your other pocket from ruin and your personal catalogue of life lessons from chagrin.

    Whilst in a shop, the shipping carton for an item I had just purchased had an information panel I wanted to keep. The salesman was about to go in search of a box cutter, but I assured him I could sort it myself. The little No 4 went straight to work without raising an eyebrow. Seconds later the information panel was in hand, and the No 4 slipped back into my pocket.

    Now, hidden in the layers of thick cardboard was a large staple. It curled the blade's edge, so badly that my kitchen steel could not correct it. Some work on a coarse stone, then on a Sharpmaker, and finally stropping, restored things.

    This event shows why the No 4 is a good choice for an expendable pocket knife. True, many other little bits of cutlery would fit this role, but I would rate a No 4 as probably the top performer; the cheapest option.

    It is also handy for trimming jobs where you don't have much access, if a Stanley knife is too big to be used. Also, the belly on the tiny Opinel blade is sometimes more appropriate than the sharp point on a utility knife. With care you can go by feel to score or slice some materials, such as vinyl sheets, without leaving a mark on the furniture surface underneath.

    Opinels really excel when it comes to slicing. Despite its miniature proportions, the thin blade and the renowned convex grind lets it glide through materials that other blades would balk at. I had to halve a tough plastic bottle lengthwise. Including the hard thick threaded spout. My trusty Case, with its hollow ground blade, hung up in the spout. Substituting the No 4 finished the job in no time. A slight rocking motion helped it bite through the hard tough material.

    When using a No 4 on apples, although the blade is short, juice tends to not run into the joint if the knife is held above the fruit, tip down. A hollow ground blade, even one quite a bit longer, will often channel fruit juices right up and into the joint of the blade. In this instance, in my opinion, the thin convex blade gets the nod even over the respected SAK equivalent.

    And the diminutive No 4 is as sheeple friendly as can be. It looks, and is, disarmingly old fashioned. All at a negligible 10 grams. If lost or ruined, this little knife is easy to replace. Very simple to sharpen and maintain. Value for money? Off the scale. EDC with no worries.

    So, the tiny Opinel No 4. Maybe the ultimate small, expendable, "sacrificial," sheeple pleaser that will also serve you for many years to come. Simply ideal!

    Service from HH? Sublime.

  4. A fascinating advert for a bigger knife.Review by
    I bought the 5cm bladed Opinel from HH (Top service, great prices, fast delivery as always) out of my facintation with friction folder.

    It arrived today and my first impression? "Bl**dy h*ll it's small! And blunt!". A good look over it and I can see and feel the quality in this blade that belies its price. It is small but very well made.

    2 minutes on my blade-medic (bought through HH) and 2 more on my strop (again, HH) and the thin, carbon steel blade on this knife is now a scalpel. Really easy to sharpen.

    My new, jeans' watch pocket EDC!

  5. A toy knife thats sharp.Review by
    Its classic looking and cheap but there are too many problems as an edc. Its too small so you'll do yourself an injury trying to do anything but the lightest of tasks. It weighs almost nothing and the wood is slippery. The blade is thin. All are limitations of its usefulness as a tool. In your pocket its quite a lump because of its tube like profile. Theres no spring so make sure you close it properly. The tip is too wide and makes it hard to stab into packages to open them. Also I dremelled a recess in the wood to expose more blade so I can grab it to open more easily. Sorry but I think any cheap classic penknife woould probably be better. (Posted on )
  6. This classic folder every knife collector should have !Review by
    Great quality... razor sharp (Posted on )
  7. Staple of my edcReview by
    Regardless of where I go, or what the occasion I can guarantee that this little thing is tucked safely in my pocket. For the price it is a truly fantastic and well made knife and it's easy on the eye as well. Can't go wrong with it. (Posted on )
  8. Best budget backup Review by
    Initially bought a size 6 as a winter project to modify the handle. Once it came out of the packet though I was wonder where it would fit in my kit. Sharp enough to whittle and big enough (just) to be comfortable in the hand. Would buy another one maybe a 7 or 8 for regular usage. (Posted on )
  9. very smallReview by
    I bought the no 3 and it is very small . it has a thin blade that is very sharp. this makes it great for slicing. I bought this knife to bump up the total price to get free shipping and had i known it was this small i dont know whether i would bother now I know how small it is. I think I shall use it as a marking knife for carpentry or as another review said in a first aid kit (Posted on )
  10. wow this is smallReview by
    And sharp (Posted on )
  11. it is what it isReview by
    It's a tiny opinel. Yes it is thin and for that reason you can get this little thing to scary levels of sharpness. It's a folding scalpel.

    Can you snap it ? Yes of cause you can if you are that way inclined.

    It's a fun item that you can buy with pocket change but it won't chop trees down lol

  12. good little opie,Review by
    Ive a few opinels and love them all, this litte knife is ideal for small jobs and keep mine in with my first aid kit, must have for any opinel fan, (Posted on )
  13. Nope, it's a bad wee knife!Review by
    Upon closer examination I became enraged by it's fragility and so I snapped the blade in half like a cheap feeler-gauge. This knife compares to a Spyderco Bug in the way that the Wright Flyer compares to an A10. (Posted on )
  14. Blade too thinReview by
    Get a Spyderco Bug, Sog Micron, or Vic SD instead - this blade is so thin that you can snap it with your fingers easily. It's a toy. (Posted on )
  15. Good wee knifeReview by
    Small, sharp and cheap. Exactly what I wanted. (Posted on )
  16. Small and sharpReview by
    It is a miniature knife indeed. But it cuts over any expectations. The blade is thin indeed, it is to enhance you cutting even further. With some you do not use a miniature knife for heavy tasks or as a prybar so there is no chance for it to brake. It is perfect for the overly sensitive Metropolitan public, when you really need to cut something and though a classic knife in your pocket is fully legal, you still need to be cautious, not everybody knows the law and you may be getting some weird looks. That's when this little wonder saves the day. Use it wisely (Posted on )
  17. cool but miniReview by
    Very excellent cutter but the blade is very thin and fragile. It is microscopic please check the specs before you buy. (Posted on )

Mr Nick Fletton answered on 19 February 2019
In England and Wales under Section 139 of the Criminal Justice Act 1988 it may be an offence to have any sharply pointed or bladed instrument in your possession, in a public place unless you are able to show good reason or lawful authority for doing so. Good reason’ for carrying a knife may be shown by occupation as a farmer, joiner, estate manager, electrician, recreational stalker, plumber gameshooter, angler or anyone else who has reasonable grounds for expecting to need a knife whilst pursuing a lawful activity. E.g. someone wild camping and building a hide or fire. Carrying a knife in public must be in connection with the activity for which it is needed; leaving it in your car or going into a shop with a knife in your pocket if you are returning from or going to a place where you use it etc. would usually constitute good reason even though you do not have an immediate need to use the knife on the spot.
There is an exemption in law for folding pocket knives. These must have cutting edges of less than three inches and do not lock. Due to a court case it was ruled that a folding pocket knife “must be foldable at all times”. Due to this ruling, a folding safety locking blade is treated as if it is not folding , but is fixed. The blade length is therefore irrelevant.
Knives such as Opinel knives, which utilise a manual twist collar to hold the blade in the open position, are termed to be lock knives regardless of length of cutting edge. If you own an Opinel or similar knife that relies on a device to prevent the blade from closing whilst in use you will need a “good reason” to have one with you. It is reasonable to have one for ‘work’ purposes as described above and to say that you have chosen a knife with a safety mechanism to protect your fingers whilst using it.
