Short of cutting food,I haven't found anything else that serrated blades cut cleanly enough, to warrant actually liking them!They have their place,such as mentioned before ie., Ferro/Mischmetal rods,Seatbelts, feathering tinder,Ice,etc.

Pretty much ideal. I also quite like the serrated SAK with the serration at the front.

Or my Byrd Wings - decent plain edge, serrated there as back up if needed

I find a serrated blade a very useful work tool, for opening cartons, cutting foam pipe insulation, cutting packaging materials, and sometimes cutting rope.
Fine as a work tool, but perhaps less useful as a survival tool, for which a good plain blade is arguably a better choice.

I use a fully serrated blade for gardening, as it cuts through roots better than a plain edge. It also stays sharper for a little longer when digging in dirt. My EDC Leatherman Wave has a serrated blade which I use for cutting up cardboard boxes for targets or recycling, and for rope and light wire. For the last two years, I have been using a Bear MGC partially serrated knife for deer hunting. I'm trying to avoid having to carry a bone saw. It works OK, but I wish the serrations were on the back about an inch from the handle. I have been thinking about re-profiling the tip of the knife to remove the point for field-dressing work.

I use a serrated blade for cutting rope, vine, small branches, etc. it's not something I use every day but I like to have the option. I've adopted hubby's old Ruko fixed blade, because it's got the serrated part on the spine so it doesn't interfer with the regular blade.

I have a few SAK's that have a partial serration and they are ok as a pocket knife. The blades cut meat really well and other things, like paracord. I much rather have no serrations though.

For a fixed blade, I do not own, nor will I own a blade with serrations. Not for an outdoors knife in my opinion. I don't need to cut any ropes. Serrations are ok on some kitchen knives, as long as they stay in the kitchen.

My EDC $1 folder has a half-serrated blade. It is primarily a work knife for me and the serrations perform well on cardboard, duct tape, etc. I sharpen it daily (its a $1 knife after all) and it does yeoman's work for me.

My EDC SAK has no serrations and cuts electrical cords like butter.

The serrated part will start cut on smooth and tough things like plastic and bark much easier than plain edge, especially on knives with softer steels.

That looks like a very useful blade
