I think you will need to think about your trips and where you would like to of had a knife.  I like a knife on my belt and I have used a fillet knife but they do not have a snap on the case so they fall out when I set down.  What I carry now is a small hunting knife on my belt with a snap on the sheath.  I also have a fillet knife in the bottom of my tackle box. You may want to look for something you would use while not on a canoe trip. When not on trips I carry a small 3 blade pocket knife.  Maybe a kitchen tool.

Bench-made is famous for their knifes, especially for their combat folders.
I'm not suggesting camping/canoeing or any outdoors activity is on the same level as " combat", but knifes made for combat are the best they can be and will take whatever punishment you can dish out.

You already have a fixed blade knife, a very good one in the Russels # 1.
It has served you well for the things you've used it for, and would even do more, IF it came down to it. You could use it to split small kindling by using a small log/rock to drive it like a wedge. Not good for appearance, but the knife would take the abuse. You could lash it to a limb for a make shift spear for food/self defense.

My point is that I would get a combat folder type knife to augment the straight blade you already have. Something that can be opened with either hand, has a belt/pocket clip that you can adjust for tip up/down carry, and a combo serrated/fixed blade.

I know you probably don't carry a knife for self defense, but unlike a firearm that needs to be regulated/licensed, a combat folder with some exemptions is legal to carry in almost every jurisdiction.

A lightweight combat folder could and has proved valuable in situation from self rescue to self defense.

Just something to consider. My Dad was a farm boy. He never left home without some type of pocket knife on him. From cleaning his finger nails to cutting whatever, he saw them as a tool ANY man would find valuable sooner or later.

Excellent choice
I didn't see it offered in a combo edge, but that's just a minor thing.
I think you'll be more than satisfied.

Combo edge = best of both worlds.  Plain edge when you want it, serrated edge when you need it.  Serrated edge will slice through rope, seatbelt, packstrap fast if you need to, i.e. you swamp your canoe and are entangled in something and likely to drown.  Won't leave a nice clean cut, but will get work done in a hurry.  Also tends to stay sharper longer.

Pointers anyone...on sharpening those serrated blades?
