This is the pocket knife I carry on a daily basis, it's also perfect for harvesting mushrooms.
EDIT: Sorry I didn't see your budget. For under $100 I'd recommend something like the Kershaw Leek. Some Spyderco knives are around your price point too.
Also, if you're willing to get something fixed-blade (non-folding), there are a lot of options there too. Mora knives are hard to beat for the price.
A decent knife. I have one of these.
Edit: for the record, I posted this before the lasybugs thing took off
You're not going to make any great progress on a PC build for that price. Besides, PC tech is changing so quickly, you shouldn't buy any one piece of it until you can buy all of it.
If you're looking for X1 games, I'm a huge fan of Destiny, but it's not for everyone. If you're looking for more of a sure hit, check out Shadows of Mordor or Dragon Age: Inquisition.
If you want to change things up a little, here are some of my favorite purchases (I'm a minor Amazon addict):
A super high quality door-hung b-ball hoop (you'll want to buy a nerf ball with it, the one it comes with is dangerous to valuables in the room)
A classy and useful EDC knife (there are lots of options on this front, /r/knifeclub has great recommendations)
Check out my sub /r/everymanshouldhave for more recommendations like this. It's not super active of late, but it has some great suggestions if you look at the history
I actually got the firefighter version of this knife off of ebay, but nearly the same price and almost EXACTLY the same. Do not buy this knife.
The screws will eventually get worked out of their holes, the knife is not as sharp as it should be no matter how much you sharpen it, the seatbelt is rumored not to work so I've heard, haven't tried it myself and I've heard some even say that the window breaker will become dented on the window.
If you want a better EMS knife-
This is one of the best knives for just a basic non-serrated blade: The Kershaw Leek
For a serrated blade that is nice and tough: The SOG FLASH II
For a great rescue-specialty knife: The Gerber Hinderer
EDIT: For another simple go-to blade: The Kershaw Skyline If you are a NutnFancy fan, here is his video on it. Kershaw Skyline: "EDC Hall of Famer" by Nutnfancy
