The venerable F1
I've owned this knife for years now and keep coming back to it. The VG10 keeps astonishing me. Very easy to sharpen and keeps a good edge longer than you think. Whilst the leather sheath looks the part, the no nonsense plastic sheath is my preference. It's easy the clean and if necessary disinfect and comes up like new. The longer I own it, the more I see it's a great knife for any task, in any condition.
