I own a few Doziers and prefer the near horizontal (crossdraw and strong side abdomen capable) belt sheath. With the appropriate dress code it can be concealed and conveniently and quickly accessed in either standing, sitting or lying down positions! Quick on and off allows for "disposability".
As for the shoulder rig, it is a simple adjustable single piece strap of nylon(?) At one end is a sewn belt loop which starts at the strong side abdomen (between pocket and zipper)and travels strait up over the shoulder and dips down the back to the opposite side and is secured by the other sewn loop. The removable sheath (horizontal belt carry capable) lays on top of the breast area unlike the popular shoulder rig for handguns which lay under the armpit. IME, I don' t recommend this rig for barrel chested individuals. The butt end is often pushed away from the body and sticks out like a sore thumb. The attached belt clip makes it worse. The end loops should have pull the dot snaps for quick on- off capabilities.
As for the NY Special, it is best suited for a smaller hand as the handle is compact. Its blade configuration make sheeple shriek. Any of Bobs tacticals (Agent, Bodyguard) can be made with a shoulder rig and extra sheaths are availble custom fitted to the particular blade.
But all in all, you can' t go wrong with a Dozier. High quality handmades at a reasonable price.
