I actually don’t mind a combo blade for certain things. Ever cut automotive heater hose with a pocket knife? The straight edge starts the cut through the outer rubber, and the serrations dig into the woven core. Same goes for rubber break lines. Works well if you have to cut seatbelt or other webbing material, as well as natural rope, etc.
One of my favorite EDC’s was a Kershaw Blackout with a combo edge. Was very versatile in the garage, out in the woods on a dirt bike, or down at the dock on the boat. Never knew what I was gonna need the knife for, and even when the edge got dull, the serrations would still cut.
Now, I prefer a straight edge these days for EDC, I’ll still throw a combo in my pocket on certain days, if I know I might need it. For that Nakamora, I’d probably see if I could return it for what you want, as it’s a good chunk of change, but that doesn’t make it a bad blade.
