You can' t go wrong with any Dozier fix blade. No matter the model you choose, it will serve you well. Backed by many decades of knifemaking experience, Bobs excellent heat treat in his D2 steel blades are made to be used. For an average range of $150 you will get a handmade blade backed with a lifetime warranty and one of the best and friendliest customer services in the industry. Wait time is usually no more than 2 months max in my experience. And a good supply of his catlaloged models are usually on hand.
My personal (no pun here!) choice among my various 4 finger grooved models would be the Personal Utility. I have a few of Bobs other 4 finger grooved models which include the Strait Personal and an
uncataloged Drop Point Personal. And really do prefer the clip point shape of the K-9 Personal Utility. It is a bit more versatile (i.e. as a thruster for personal protection!) with its pointier tip and a functional set of finger grooves as our own Paracelsus and Ebbtide has already stated.
Notes: when requesting a blade from the Doziers, you may want to ask for a bead blasted finish on the micarta scales as they all come with a standard smooth finish. In my experience, if I am intending to really use my blades, I find that a smooth/ polished finish just won' t do it for me. Better yet, have it checkered afterwards!
Also, the bar stock of D2 which is used in all of Bobs blades do vary in thickness from batch to batch. Not all the time. Nor a whole lot but something worth inquiring about.
Good luck with your Dozier!
