I have two of them, the ringed version and the stubby. In fact, I liked the stubby one so much I went ahead and got the Graham Knives custom version. The ringed razel is a little bigger, and has a lot more handle sticking out of your pocket. For me, it was too big for EDC so it stays in my car. The stubby is very useful. Having that chisel tip has come in handy many times for prying and scraping. This little knife is built like a tank.
The cons: really cheaply made sheath. Also, the sharpening choil tends to get snagged on fibrous materials.
