Your question is very much lacking in detail.
Is this a nipple wrench for rifle, sxs shotgun, revolver, side hammer pistol, caplock musket or what specific application? I have a flintlock with a flag guard that uses a nipple wrench to remove the nut holding the flashguard in place. My revolver nipple wrench is smaller than the wrench for my rifles.
Do you want to remove the nipple with the lock in place or with the lock removed? In either case I want a wrench with a long enough barrel to clear the hammer. I have a custom made one with a very long barrel to clear a tall hammer.
I want my nipple wrench to securely fit the flats of the nipple. It should be sturdy enough to remove the nipple when fouling has filled the threads or when corrosion has created it's own version of locktite. Keep the nipples clean and install with a good grease such as RIG or a high temperature never seize lubricant. You only need to tighten a nipple to snug. Over torqueing is not necessary.
Most wrenches offered by the major suppliers will be more than adequate for the intended application. No one brand is necessarily better than any other and none have universal applications. The old T/C version served as a nipple wrench and wedge puller but you needed to remove the lock or barrel to get access to the nipple.
