Years ago I put 3 in 1 oil on them and then maybe not use the tool again
until next summer. Since I was chiseling construction wood. Oil didn't
really matter. Today, I haven't been putting anything on them. Have a
recommendation? I read about putting Topcoat or wax on planes, probably
should do the same with chisels I suppose. Is there anything you can do to
prevent further deterioration of black spots or are you doomed and its just
going to be the pits..
Once you have a rust spot, it will never re-fill. It will only get larger
unless you prevent further rusting - exposure to moisture.
Here in SoCal, its not a huge problem but when I want to protect a tool that
sees little use, I will spray it with a mixture of motor oil and kerosene (5
parts oil - 1 part kerosene). Then wipe the excess off and put it away.
This may not help in high humidity areas but it works like a champ here.
BTW, garden tools get shoved into a bucket of sand mixed with oil before
storage in the shed.
Yes, I'd agree with that.
My usual bench chisels are Japanese though, so this problem doesn't
arise. I could either lap a pit out of the back in a minute or two, or
leave it alone if it's in the hollow.
For chisels I use Japanese "camellia" oil, which is actually fish oil
with a scent added. Buy it from any quality toolstore, it's common
these days. It's persistent, non-oxidising (measurably), non-gummy and
lets you go straight into carving lime (basswood) without leaving
marks. I also keep a bamboo/cotton waste oil pot full of the stuff on
For swords I use camellia oil, made from camellias. I get this from a
Chinese herbalist, sold as a hair product.
