The bottle I reach for when a new knife shows up with a little friction in the pivot. Kershaw recommends it for its own knives, Knife Informer named it the best budget knife oil, and one drop makes a mid-range folder feel buttery smooth again. I would still buy KPL first. The reason is mostly the bottle, not the oil.

The verdict
Direct answer: it works. I clean a knife down, put a drop in the pivot, and it feels buttery smooth again. Kershaw recommends this oil for its own folders, and Knife Informer named it the best budget knife oil. The catches: the plastic nose is too wide for a lot of pivots (KPL has a real needle), a white wax-like buildup has shown up in my bottle, and it is not food-safe despite the non-toxic label. Based on what I hear from other enthusiasts, I would still recommend KPL over it. The knives it goes on live at the pocket knives hub.

Kershaw Knife Oil
For: a mid-range folder with a little friction out of the box, and anyone who wants the one bottle Kershaw itself recommends for its knives.
Skip if: your knife touches food (food-grade mineral oil is the BladeForums answer), or you want a needle tip for a bearing pivot (KPL's bottle has one).
When I use it. I use this often for most new knives. Once I've flicked them out a couple of times, I can feel if there's any friction, and usually there is, no matter where the knife is from. The higher-end knives usually come even smoother, so it isn't necessary, but mid-range knives have a little bit of friction out of the box and can use a little drop of oil.
Does it work? I'm curious to see how this oil will compare to the KPL oil, since that's the gold standard, but as of now this does the trick. I can clean down a knife, put a little oil in it, and it feels buttery smooth again.
The bottle. There is some buildup of some white, wax-like substance in the bottle, and I'm not sure where that's from. Also, the needle is not as good as the KPL, since the KPL is actually a long metal needle that can fit into almost every groove. The plastic nose on the bottle is kind of wide for many applications, so you've got to get creative.
KPL or this? It does the trick for most cases, but I would recommend KPL over this, based on what I've been hearing and seeing online from other enthusiasts.

What testers and the forums found
Knife Informer, Best Knife Oils roundup: named it Best Budget Knife Oil, 'very cost-effective' with great results. Its one con is the missing needle-nose tip. It ranks below Sentry Tuf-Glide (best overall) and KPL Knife Pivot Lube (best premium), and questions whether the premium upcharge matters for most people.
Kershaw official product page: the maker's spec source. 20 mL bottle, SMT sub-micron formula, non-toxic and non-migrating claims, and the seven-step application procedure.
Kershaw product-care guide: says most household oils, WD-40, 3-in-1 or gun oil will keep its knives running, then recommends its own Knife Oil. That is an honest guide to how interchangeable this category is. I bought the bottle anyway.
BladeForums, food-safe SpeedSafe lubrication thread: for real food contact, the thread's answer is food-grade mineral oil or a Lubriplate FMO-class lubricant, not a branded knife oil. That is the kitchen-knife answer Kershaw's marketing leaves fuzzy.
KnifeCenter product page (KEROIL): lists the classic KEROIL SKU as a 12 mL bottle, which is where the size mismatch with Kershaw's current 20 mL description comes from.
Pros and cons
What works
One drop in the pivot and a mid-range knife that had a little friction out of the box feels buttery smooth again. That is what it does for me on most new knives that come through.
Knife Informer named it the Best Budget knife oil in its roundup: very cost-effective, great results.
It is the oil Kershaw officially recommends for its own knives in its product-care guide, SpeedSafe assisted-opening models included.
The drop-dispenser cap puts one drop on a pivot without taking the knife apart, and at 0.8 oz the bottle fits in any kit.
What doesn't
No needle tip. The plastic nose is wide for a lot of pivots, so you have to get creative. KPL's long metal needle fits almost every groove. Knife Informer's one listed con is the same one.
A white, wax-like buildup has shown up inside my bottle, and I do not know where it came from.
Not food-safe, whatever the non-toxic label says. The listing carries a California Prop 65 warning, and BladeForums points kitchen blades to food-grade mineral oil instead.
Like most wet oils it collects lint and pocket debris, which is why Kershaw's own directions end with "wipe the excess".
No. Kershaw markets it as non-toxic and non-migrating, but the listing carries a California Prop 65 warning. For knives that touch food, the BladeForums answer is food-grade mineral oil or a food-grade (NSF-rated) lubricant.
How do you apply Kershaw Knife Oil to a folding knife?
Kershaw's own procedure. Clean off debris and dry the knife. Shake the bottle well. Put one drop on the pivot and detent. Open and close the blade a few times to work it in. Wipe away the excess. Add a light coat to the blade before storage.
What size is the bottle, 12 mL or 20 mL?
Both exist. The Amazon title says 0.4 fl oz, about 12 mL, which matches the classic KEROIL SKU that KnifeCenter lists. Kershaw's own copy on the same listing, and its official site, say 20 mL and 0.8 oz. Either way it is the same small drop-dispenser bottle.
