Lubricants and corossion-protection: my overview

Hi there,

I have read some interesting threads here regarding knife care. Lubeing and applying a protective coating to be precise.

I will try to give an overview of what I, personally, have found out.

Let me tell you, my own practical experience is very limited. I use spray oil for bicycle chains, it does NOT run and if it gathers to much dirt, after 5 minutes you have fresh layer. The oil sprays on, some solvents seem to evaporate and the oil is thick, clingy. No colouration or nasty odour. This is use only for the parts that do NOT move... to prevent rust.

For parts that to move and are thus subject to friction and wear 'n tear I use a high-grade synthetic quickdrying spray for locks ("Abus"). The pivot area and the lock of my folders are treated that way. That DOES stink and costs a lot.

I regulary rinse them down with hot, fresh water and clean them with gentle "old-school brown soap". When needed I use alcohol. Set them halve open in a ventilated room and let them dry. Then the whole oil story again.

As fixed blades have no moving parts, they are much easier to maintain and less susceptible to corossion. No nooks and crannies, no locks or pivot area that wear out.

WD-40 is a No-no or so it seems, only to be used to expel water and to clean.

The big issue than lubricating is not the same as repelling rust. Oil happens to have, more or less, these two properties. There's no reason why manmade alternatives should carry both. A rust-repellant should seal the knifemetal of from surrounding air. A lube most reduce friction.

!!!!It seems rather likely that the steels, finishes, treatments "desire" their own personal agents. That could explain (along with frequency and mode of application, use and environment) the mixed results: some rave about one product, others are indifferent. The findings of individual users are to limited to be generalized.

Best corrosion product seems "Sentry line"I mysel will order the bigger bottles of Smooth-Kote along with Tuf-Glide, no need for a silly expensive rag). Best lubricant seems "Militec".

Bottomline seems: WASHING with lots of hot water and soap, carefully allow to DRY. Use ALCOHOL for any leftovers. WARM up the knife but not in a way that it would burn you, apply the SENTRY stuff, let dry, reheat, then the MILITEC.


Bye, take care.
 
I use Break Free CLP on all of my knives (and guns), and it seems to do a very good job of Cleaning, Lubrication, and Protection (from rusting).
 
Well, that one pught to be nice too... but I heard it could attacks some finishes/materials... That it can be too agressive. I do not really know actually.

Take care
