the o rings IMO, owning many pry bars and tools like yours, will be a nightmare. Something to lose and to wear down. Also a sheath is not something necessary for a pry, again something to keep up with. These items wind up on key chains or belt loop etc. Hundreds of these on site for sale now, but everyone is trying to get into the market. Many can be purchased for < $50, while others bring far more, and for what reason?? You asked, and I wish you the best. Also add color, men seem attracted to colored gadgets, lol.
