My small collection of knives range in price from $10 to $200. I see no correlation between price and grip. My second least expensive knife, a black-washed CRKT Squid, is annoyingly slick. I like the little thing, so may get one with a G-10 scale some day. Another annoyingly slick knife is, price wise, in the middle of my collection, my Civivi Shard. The G-10 has almost no texture, and the carbon fiber overlays are almost frictionless. I must admit, however, that neither the Squid or the Shard feel insecure when gripped. Their slickness is a concern when handling them when not in use.
My two most expensive knives have great grips despite having handles of higher grade materials. My Bestech Engine, with a titanium frame and carbon fiber scale, has more than enough grip for its designed purpose, and is not slick while handling between use. While both materials seem slick at first glance, there is some degree of microtexture (a surface feel that I cannot visually detect) that works during handling. Also, each has a macrotexture (design morphology) that works very well during use. My Bark River Mini Fox River has canvas micarta scales, which have always provided adequate grip.
