I'm sorry if this question is too noobish, but is it ok to use 10W40 to lubricate the pivot of my folding knives?
 
Motor oil is good but there are better options.

Use EEZOX, Breakfree CLP, or FP-10 and you'll get both lube and rust protection. 3-in-1 Oil is a good lube but not so good at rust inhibition.

Yes, you can use motor oil to lube your knives. It won't hurt anything. However, if you use 'em for any food prep it'll leave a nasty taste.

Duh...of course you can use 10w40...my bad. I think I had a senior moment there. 10w40 is just fine as are all motor oils. Gun guys seem to prefer synthetic and seem to prefer 5w30 but...

Man...I saw W and 40 in the same sentence and...well it was a brain fade.

Thanks for the replies.

I'm probably going to order the BlueLube from Benchmade (funny thing but I like the way my two BM folders smell) but I recently bought a SOG knife that needed some lubrication badly and I couldn't resist to use some readily available 10W40.
 
Most "fancy" gun oil or honing oil is really not very fancy chemically speaking. A point is well taken about motor oil...a lot of attention is lavished on the chemistry of motor oil to maximize its lubricity...so as a lube, I doubt that you could ever find a better product. They do not, however intend it to inhibit rust so there are other options there but as an oil, it will inhibit rust up to one degree or another. Plus they do not intend it to come into contact with clothes so it is messier than a fine, thin gun oil like Rem-Oil or something like that.

You of course are asking about lube so 10w40 away with a clear conscience. I have used 5w30 as a honing oil in a pinch and, while a terrible slippery mess, it sure did suspend the metal shavings...something else it is supposed to do.
 
I've been using 10w40 on the pivot of my folders for several years. It works pretty well, doesn't seem to suck up lint and dust as much as straight mineral oil or 3-in-1 and cleans up easy enough if you decide to remove it. I've also noticed that it doesn't tend to flow and leak out the knife like some thinner lubes. So I guess I like it quite a bit. :thumbup:
 
Motor oil, 3in1 oil or any heavy oil makes the action sticky. BM blue lube is very good and will work many times better.
 
Living in a rust-prone coastal area, I use 30W motor oil as a rust-preventative for many steel and iron tools, and find it works as well or better than more expensive products. For carbon steel blades, I just wipe them with an oily rag I keep in a baggie on my bench. It does taste bad, like TR mentioned, so I don't use it on food knives.

You can use any motor oil on your knife.
You can also use WD 40.
 
When he came over for a visit, he saw me choking and spitting and was smart enough not to eat any of the sliced food I offered him.

D*mmit.

I like to use bicycle chain lube. Specifically TriFlow. It lasts a really long time and you can get it at any bike shop for around $6.00. It also smells nice and doesn't thicken in the cold. Triflow and White Lightening also have dry lubes that don't attract dust and lint. They're wax based and work well too. You can use just about anything though but I'm a bike mechanic so that's what I have at home.
 
Wd 40 is NOT a lubricant. Water displacement # 40. It has been banned in most aircracft maintenace facilities. Best bets are Rem oil and Bluelube from Benchmade.
