KPL Knife Pivot Lube vs Mineral Oil & Blue Lube Measured Test (Best Knife Oil Series) 

Awesome, thank you for doing this! Makes me feel more confident that I am not losing out by only using mineral oil. Food safe and lubes well. Win-win. I am thinking it's fair to leave out the 129. It seems like it's way too far off to have not been a fluke. Those bottles you bought look perfect. I'm going to grab some for myself. It's pretty cool that nano lube found your tests and contacted you about trying their products.

I've only used mineral oil on my 60plus collection because it's cheap, readily available and food safe but I've always wondered how it compared to more hyped methods. glad to see it's performs reasonably well. I use a hypodermic needle to apply the oil ...works great.

I've used KPL, nano oil, Diawa reel oil, EDC spray, REM Oil. The mineral oil is just as good and costs $2 for a lifetime supply. I would love to see a link to the bottle from Amazon. Thanks again for the video 😎👍

I would like to also see a comparison to 3-in-One oil. Thanks for doing this, it is nice to see an actual comparison vs advertising hype.

And the plot thickens.... sorry couldnt resist 🙃. Keep up the good work 👊

I'd leave out the 129 as it deviates too much from the rest. Great test method, I love this stuff. Thanks! 🤘🤘🤘

From an engineer, 129 would be considered anomalous and requiring a total retest. You can verify it by recleaning it, re-lubing and retesting. Great job man. Keep up the good work. You ROCK!

Hum, happy I came across your channel, subbed. Was about to buy KPL and ship it in (i'm from the Caribbean), I may just go to the drug store and get some mineral oil instead.

Awesome testing like my KPL

Good video. For pure results do 5 pulls, discount the highest and lowest numbers, then average the remaining 3 values. Also, mineral oil is food safe. Something to consider if you use your knives for food prep or eating.

Very nice breakdown of the mineral oil! Obvious improvement from the 129, but wonder what the retest would show? Maybe just needs more time to lube the internal parts? Like the testing! Keep it rolling!

Love these videos very interesting results and the consistency using the hot glue placement is genius. Ignore the 129 I say that mineral oil is very impressive. Also check out hops 9 and daiwa reel oil (I have both if needed) sigh I need one of those applicators but not 12.

When I was in service we had solvent, linseed oil for wood, and mineral oil for metal. it all came in big squared off metal containers.

Appreciate your work here. Do you have a video on adding the thumb stud to the Statera? I also can't seem to locate those particular refillable oilers on amazon as most are plastic bottles? Subscribed.

Keep the practical test coming. It would be interesting to see the lubricants abilities over time. We use the knives for extended periods before we re-lubricate. Just a thot. Thx for your time and efforts, Furbs

Would be interesting to do a long term test, lube it up, let it stand a week and then test. Lube that doesn’t stay put is less helpful then something less likely to run. Why lube has weights I believe. Great test, I also agree with other comment do 5 and throw out the high and low.

Have you thought about also trying to test how well these work after a longer period of time? Would be interesting to see how they hold up, but it seems that might be a lot more work and/or have a lot more variables to try to control for though.

I wonder what the results would be to lube the detent ball as well. Of course that needs to be cleaned between the products. I usually put a drop on the ball if the knife has been sitting long term. The liner lock is always putting pressure on the blade stock Lol what if kpl was repackaged mineral oil haha

The 129 seems to be a fluke. Very interesting test....thanks for sharing!

Results, in case you want them quickly: Shown on screen: KPL: 97.7 g Blue Lube: 105.7 g ---------- What I calculate based on numbers you gave in video: No lube (control): 107, 116, 103 = 108.7 g Mineral Oil (leaving out the 129): 96.3 g

Thank you for doing this! Given that the video is from ~3 years ago, Amazon no longer sells the 15ml hard plastic bottles with steel needles. Any idea where they can now be sourced?

I’d be curious to see how it lasts ... run the pull test after a week of carry and see which ones have the staying power

Interesting results. I'd be curious to see several identical knives with the different lubes over an extended period of time. Does one lube degrade or get "gummy" vs continual lubrication... just a thought...

I currently use mineral oil, but thinking of using blue lube. However, would adding blue lube over the pivots with mineral oil affect smoothness? Or would it counteract and make it more gunky?

I just almost got pharmaceutical mineral oil to use on my knife Pivot Point but then I came across this. Food-grade mineral oil lubricants for food machinery contain corrosion inhibitors, foam suppressants and anti-wear agents, even though they are authorized for contact with food. Pharmaceutical-grade mineral oil has to be free of all impurities under USP standards. I guess pharmaceutical mineral is a no-go for a folding knife.

Great video! Can you link the bottles you stored the oils in?

I would like you to compare the KPL to Hops gun oil. Excellent review.

I'd like to see CLP

🤘🏼

Hey brother, not sure if it's been mentioned but I think your test would be improved by using a little block or table to lay the Lyman level on as you pull it, and also a block, vise or stopper that's fastened onto the table that you but the body of the knife against so that as it gets pulled it's not your wrist or fingers producing any sort of resistance or counterforce

I use mineral oil for all my knives when needed. It works fine for me and it is food safe. Does anyone know if KPL / Rem oil / blue lube or any others are food safe? Also how about viscosity ratings? Do you ever measure that difference in each product?

How about doing this on butterfly knives?

I'd be curious to see how a full synthetic oil like Mobil One compares.

Since KPL says their weight is 17, if you had to guess, what would you say the Bluelube and Mineral Oil would be rated at? Thanks!

Cool! Would 3 in one all purpose lube work?

That mineral oil with the funnel is actually meant for bike brakes that use mineral oil.

Yeah I say in the future do 5 or so and then kick the outlier number

Deam,, you men, meeeen!

I just use gun oil, easier to find locally than an oil marketed for knives ,which is something i would have to oreder online. I maybe wrong but if it's good enough for guns which is the last thing you want to fail do to rust or not lubricated well even ,it's got to be more than good enough for a knife .

Perhaps start doing 5 pulls, disregarding the best and worst. Some other ideas: Frog Lube, 3-in-1, Tuf-glide, 10w30... just to give reference etc.

So mineral oil wins? great review and tests!

I use Hoppe’s No. 9! If you want to check it out here’s a link for when I bought mine in a needle applicator bottle www.amazon.com/dp/B0013R67A6/?coliid=I32XD0XKUSON2G&colid=30N40U84UPP2B&psc=0&ref_=lv_ov_lig_dp_it

I think you have to throw out that high reading.

You ought to repeat the test say 100times. That would throw out a few outliers, sufficient to produce some proper significant stats. I’m not sure how good a video that would make, but the results would.

The testing does not include other things like corrosion resistance (which adds abrasives and friction); evaporativeness; how well it stays in place; or how temperature affects it's performance and how each lube creates optimal action. Also, if the washers rotate with the blade or stay stuck to the liner, then you get a differnt friction effect, lube aside. By-the-way, 3-in-1 oil has some pressure/friction reducing additives that go way beyond mineral oil. It would sell quite well if it were labeled with amphibians, reptiles or showed mystical colors. But doesn't that make it work better too? Opinion can make an oil even slicker!

Knife oil is kinda half snake oil. It actually works, but almost no knife actually NEEDS it lol. No knife is going to be faster than when it's clean and dry and properly adjusted, bearings and washers ARE the "pivot lube." Same with bearings, they're never faster than when clean and dry, lube is literally used to slow bearings down, not the other way around. So if you want your ZT to flip as quickly as possible, degrease the bearing, don't oil it. That said, a little lube will preserve parts longest, maybe keep your action consistent a little longer, but in the grand scheme of knife purchasers on Earth, the vast majority never oils their stuff, and regularly used, un-oiled knives don't one day just disintegrate or rust shut. Cleaning and degreasing is a more fruitful maintenance chore than oiling, and taking apart is almost never really necessary. Alcohol, Ronsonol, and indeed, overpriced 20ml bottles of purpose made knife degreaser, all work well, water and compressed air work great too. Spraying in some alcohol and working the pivot a little cleans things up as effectively as any Nick Shabazz treatment, 100% guaranteed, unless you like fussing with tiny screws and lock springs, knock yourself out lol. I do use tuff glide on my knives I carry with me on the saltwater, but my 20 year old never-oiled, occasionally cleaned Ken Onion Shallot still opens every time.

Drop the 129. It appears it was a fluke cuz you consistently got mid 90’s.

Like the results. KPL is over priced and over rated, just like Chris Reeves knives.
