It is an EDC, though it doesn't get a lot of use in an office environment. The warranty does state that improper sharpening voids the warranty, so I don't recommend taking a rasp or bench grinder to it. I was using a lansky diamond sharpening system to do mine, but have since switched to a basic V steel and ceramic sharpener. A double bevel edge is more durable, but I don't have the patience nor the time to do that on the lansky any more. I did have to send my Scarab in for warranty work, and they fixed it without question, even with my own sharpening.
