I have a little Primus block plane that I bought close to 20 years ago. I'm
pretty sure that I got it at woodcraft on Woburn, MA

Every couple of years I wonder why I never use it, assume that I must not
have ever gotten it really sharp.

Try as I may, it just digs in and chatters. Most of my planes are of so-so
quality but tuned to a reasonably functional state. But this one has just
new worked well.

If it digs in, it is possibly skittering instead of chattering, though both
could happen of course!

For the difference, try my web site - Planing Notes - Skitter & Chatter.

With such a small plane that looks difficult to adequately hold, I'd guess
that skitter is more likely.
