I found an old Marples morise chisel last night that looks very rusty

of that rust-remover liquid and a wire brush, from H.F., and a stack of
silicon carbide wet/dry. I'll take a before and after pic for fun, if it
works out.

For heavy rust, I always used Navel gel. Works a treat. When finished
wipe off with water, then lacquer thinner, then coat with Top-Coat type
product.

The problem is that once you clean up a badly rusted
cutting tool, you're often left with pitting near the
cutting edge which, unless lapped completely out,
will make it nigh impossible to sharpen the tool to a
good edge.


How deep could any pitting be? Give me a grinder and 30 seconds and the
pitting is gone. Then another couple minutes to "scary sharp."

Most chisels that actually get used a lot end up an inch or so shorter
than they started from sharpening over and over and over again over
their many years of use.

Decades ago, before you could stop at the local big box and buy new set
of disposable chisels for 30 bucks, cabinet shops had to use theirs down
to the nubs. It was very common to see chisels ranging from a foot long
down to a couple inches. They sharpened and sharpened for years and
years and used just about every inch.
