I second RN! The RAT 1 folder is the best I have ever held in this price range - even with a lot more expensive knives ( I do own 3 Heckler and Koch knives 1 of their original series some 10-15 years ago and 2 of the benchmade ones) you need to spent A LOT more money to get close to feeling, handling, quality and EDC potential with other manufacturers. I hate Ontario for still producing the RAT fixed ones from Randall - but boy did they a great job with the folder. Since I used it as a EDC knife, to of my friends also got themself the RAT 1 folder as soon as they could try mine.

From top to bottom
CS Rajah II (not very useable as EDC... )
CS Spartan (cool grip!)
Ontario RAT 1 folder
H&K X-15 TN (pre benchmade with the blade made from x-15 steel 150$+ range)
Gerber Bear Grylls Scout folder (I hate this knife! Probably the cheapest rip off I´ve ever held in hand! Just too lazy to get rid of it via ebay...)
