The Spyderco Endura would be a great choice. Good solid dependable knife and easy to keep sharp. There is also a Drone available for training. The Military is also a good choice. The CS American lawman with there new Tri-ad lock is worth having a look at. I have not handled one but the Lock is impressive.

JYD#14 Do you need one, of course you do it's a knife and you like knives.....
