What the hell is a knife like that going to do to something that can't feel pain? All it's going to do is make him bleed all over the place, increasing your chance of getting infected.
A trench knife, on the other hand, could pierce right through the skull. It's got better grip, and a spear-point style blade that aids in penetration. In WWI, they reported that it could even stab through enemy helmets. (Though I have not confirmed this yet.)

It can cut muscles beyond a usable degree. If you happen to be in a tight spot, you can use it to disable limbs. The handle is just fine as well, you don't need fingerholes to have good grip.
Not that a trench knife doesn't have it's uses.
If you have one, by all means use it. I'm not sure if you can find them serrated, but I would recommend having a serrated knife of some kind. Straight edged knives can't cut for crap.
*facepalm* Those aren't fingerholes for better grip, that's a goddamn knuckle duster for breaking jaws and s**t. And straight edges can cut, just not as roughly as a serrated edge, and they need to be sharpened more.
He said "better grip", not "brass knuckles".
As for straight edges, good luck cutting through clothing with that. It MIGHT happen, but I would rather have a knife that could slice straight through denim without trouble.
You just need to nick cloth, then it tears, with a few exceptions. But silk ain't practical, so that's not a worry here.
But I'll admit, I like a knife with the serrations at the base.
EDIT: slightly unrelated: You have thirty days. Why not build a Killdozer, as well as stockpiling gear? Perfect escape vehicle, even if it is kinda slow.
Generally, any vehicle that can go faster than a zombie is good enough.
An unecessarily gigantic (until NOW) redneck truck would be fantastic. Even if you slam into them head on, you don't suffer any kind of loss of function.
Even at that, you can mount a turret on the back of it.
Two things: First, the Killdozer.

Dude built this thing in a couple days in a simple machine shop. They only stopped him because of a mechanical failure in the engine followed by his suicide. It still took several hours to dig his body out of the ******** thing. Absolutely wrecked house with it before it failed. Imagine a month's work.
Second: There's a British car show called Top Gear. They do some crazy s**t, including trying to break a Toyota Tundra. The deal was, if they could fix it without replacing any parts, it wasn't destroyed. They drove it into the ocean, they even had it lifted onto the roof of a very tall building just before it was imploded. They still got it running again in less than three hours. So yeah, redneck truck FTW.
