Really depends on the type of knife. For a beefy bruiser of a a knife full liners are the way to go; you can stamp jimping in them for extra grip. If you're trying to keep the knife slim and low profile, nested liners are better because you can make the handles thinner while still rounding off the corners enough to be comfortable.
