Close to a fixed blade
Scott W.
Definitely in my edc stars rotation. To be in that rotation a folder has to be smooth, easily deployable, and be capable of doing 85% of what a fixed blade can do. This means that a folder has to lock up tight and be trusted, has to be beefy enough to do serious work. This Ken Onion knife does all of that while looking and feeling beautiful in hand. Very beefy, think Praetorian or Tac Butcher beefy.

This blade takes a razor edge, great hunting knife, Ken Onion designs some of the finest carry knives ever made, I have carried an Onion Bump for over 10 years, it still works as new.
Tank of a knife
Luke K.
Yes, it's hefty but once you get used to the weight it's an amazing knife! As soon as you hold this knife, you immediately get the sense that this knife can take a beating and then some. Engaging the blade is quick and the lock up is crisp and tight with zero blade play. I use this knife regularly and by no means baby it. If you want a solidly built work horse of a knife, I don't think you can get much better than this.
