Doug's knife really looks good based on the specs alone not to mention that I haven't heard a single bad word about it from anyone that owns one. I especially like the locking system. I think that's the safest folder locking system I have ever seen. Although even Doug would probably tell you that a sheath knife is probably preferable, there's no doubt that folders certainly are more socially acceptable for EDC. I have considered trading in my SOG multi-tool (my current EDC) for Doug's folder on many occasions. I may still eventually.... who knows.
