Presumably this is possible only with a QCTP without removing the toolbit
from the holder? If you took it out of a lantern or a rocker you will never
be able to re-insert it in exactly the same way. Or am I missing something?


If you hone it, you will need to re-set it anyway. The honing
will change the dimensions at least somewhat. This is where carbide
inserts are nice -- if you can find a sharp enough one to start with,
which is a problem. You take the tool holder (with a QCTP) out, loosen
the screw securing the insert, rotate it to a fresh sharp corner,
reclamp and replace. This makes the change without changing the
dimensions.

Good Luck,
DoN.
