I got around to visiting my favorite local commercial fishing supply house in Seattle today. It has been a good source of Mora knives and Victorinox paring knives. I found another knife that would be good for hiking and would be great for repairs, food prep and cleaning fish. It is made by Dexter Russell, model 105SC and comes with a Kydex sheath, model BS-3. The blade is serrated stainless steel, 3-1/4" long. The handle is molded plastic and bright orange.
It is much like the Victorinox paring knife that is a favorite of mine. The blade on the Dexter model is just a bit longer and thicker than the Victorinox and the handle is a little bigger too. The Dexter knife weights 0.9oz and the sheath is 1.4oz, for a total of 2.3oz/60g. For reference, the Victorinox tips the scale at 0.7oz. I paid $12.92 for the knife with sheath.
You could remove the webbing belt loop, or cut the back side of the sheath off even with the front to save tiny bit of weight, and then lash the sheath to your pack with cord, or just carry it with your cook kit. Any of these light paring knives can be covered with a plastic edge guard that can be found in just about any cooking store if you want a safe carry and keep bulk and weight to a minimum. I've made impromptu sheaths from duct tape too. With the sheath trimmed, this could be carried as a "neck knife" too and I am very tempted to do that.

If this sort of knife appeals to you and you want one with a wood handle, AG Russell makes the Woodswalker knife, which is for all practical intents, a paring knife. They make an interesting leather sheath that is like a wallet, to ride in your back pocket. They also offer a Kydex plastic neck sheath. They run more like $28 with a Kydex sheath option. The knife has a 2-3/8" blade and is 1.2oz. No weight was given for the sheath.
