Heck yes! Why not!?
The way I view knives is simple, there is a different knife that is a perfect knife for many different tasks however no 1 knife perfect for every task...
That's what's great about the great "perfect knife" hunt / journey we all find ourselves on....
Personally I've found my small sebenza 21 insingo to be the knife I've owned for many many years and still carry it today for EDC, I think out of all knives this has been my favorite and remains my favorite for EDC... for me it strikes the balance between ruggedness, ergonomics, and utility all in 1 package that can handle just about any EDC task it faces.
The only other blade that I've had as long but havnt carried as much is the strider pt.
They are both comparable in size, yet the sebenza has a much larger cutting edge, which is nice along with IMO a high quality of fit and finish all around.
Still love the pt though.
If I'm at work however, I like something larger and more rugged/tank of a knife, preferably with a glass breaker (as I've needed to use it in the past, and it came in clutch multiple times). That's when I carry something like a microtech socom elite, or Umnumzaan.
Just my thought on the matter =]
