As CRR said...Everything!
But in no particular order here are some of the many things I love about them:
1) Best people in the business.
2) Best community anywhere on the net.
3) Fantastic carefully thought out designs that provide real-world solutions for real-world problems.
4) 1095 High Carbon steel holds a great edge, is tough as hell, and is easy to sharpen and customize.
5) Full flat grinds make me really happy.

6) Guarantee allows me to really use my knife hard without getting nervous about destroying my investment (which is important since I'm not exactly rich)
7) The sheaths are just as amazing as the knives! What won me over to RAT in the first place was the injection-molded sheaths. So many great fixed blades exist out there that come with crap for a sheath. If a company isn't going to do it right and force me to have a sheath custom made they can at least just not include one at all so I'm not paying for a piece of crap.

The RAT sheaths do it right: Tight fit, smooth withdrawal, versatile carry options. What's not to love?
