About
MKM Professional Series Rigid Steel Ribs
MKM
Professional Series ribs consists of 22 differently shaped
ribs made of a 1mm thick rigid stainless steel (1.5 mm thick
for the larger ribs). The ribs have a variety of curves,
sizes, and shapes to fit a wide variety of needs -- small
rounded ribs for inside jars and bottles, plate ribs of several
dimensions, finishing ribs, cylinder ribs, bowl ribs of every
size and curve, ribs for flanged plates, etc. The smooth
and narrow edges of the ribs allow for excellent control of
the clay surface, very low drag against the clay wall,
and an unprecedented ease of use. In short, these ribs
are designed to work with you and for you in ways that have
so far been unavailable to the potter

Tips for using rigid steel
ribs:
1) To avoid grog
trails, do not hold the rib perpendicular to the clay, but
rather at a sharper angle.
2) To avoid
chatter with wood or steel ribs, re-wet the clay surface.
3) Feel free
to attach these ribs to your MKM Ultimate Throwing Sticks.
They work great.
