Yes, WD is for Water Displacing and the 40 represents the 40th formulation they tried. Displacing water is one way to prevent rust but I believe the problem is that this effect may not last long as the film is easily removed. However, I use it too, just not on my carving tools. If memory serves, the key ingredient in WD 40 is coconut oil.

I wonder how Top Saver would work? Anyone tried it?

Like Hi-Ho, rusting isn't a big problem here, but you never know.

WD-40 was developed by a Chula Vista, CA company, Rohr Industries if I remember correctly) during WW-II. They manufactured airplane parts and stored them outside. Chula Vista is located on San Diego Bay, so corrossion was a problem. They needed a solution and WD-40 is what they came up with. It's good for a lot of things, but there are better corrosion preventers available today. My personal favorite is a product called
Corrosion-X. It's used by the military as a corrosion preventive (there is an NSN for anybody interested). It is also good for many of the same things WD-40 would be used for. A can of it is more expensive, but you use a whole lot less. In the end, the cost is probably equal.

Well I use "Top Saver" and the other things in the kit and they work fine on my saws....

One way of protecting tools is not loaning them out!

I use WD-40 simply put as because I can get it anywhere, and it is water displacement I want after working with them. Small can on the bench spay and put up.

I agree there are indeed many other products which will give a better protection, but for day to day there are few products at the cost which will displace water and add some protection. If I was sealing them for a long time, I would

1) spray with wd- 40 ,
2) wipe dry
3) use plastic tool and dip the blade of each tool. (protection from air and bump damage)

Plastic tool will only stick to the tool if they have no oils on them.
There is a better product used in industry for covering tools but it is not as easy to get.

Kenny can I borrow your mirco tools ?
