The KT4 Grind: The KT4 grind (above;
screen at right) is essentially a CHV that is
only applied to the middle half of the ski. It
works best for tech skis in cool, middle, and
warmer snow temps and low, mid, and upper
humidity. The smooth base adjacent to the
edge allows for less friction during re-direct
and stivoting moves. (This ski has inerts which
are visible, too, directly next to the edge)
The KT4 again: The grind (at right) is only
across the middle half of the ski, allowing skis
to be re-directed or stivoted more easily.
Screens, from the top: ML3, ML3d, RTK and CHV.

The CHV Grind (above right): The CHV is a newer, yet very proven grind. It’s found on many World Cup skis today, and varying the
depth creates a ski that works well in very cold and dry (shallow depth)
or warmer and more humid (deeper depth). This is a great choice for
speed skis.
