Flat grind
From Spydiewiki
Flat ground knives usually have a blade that is flat and tapers from 0 to bladewith completely flat making a V- shape. These blades slice very well. The Flat grind blade differs from a Full Flat grind in that the grind does not go all the way up to the spine, but rather just below the spine, leaving more material in the blade for added strength.
And example of a Flat ground blade is the FB53 Skoli
