This knife is great. The large size and textured grip work great for my large hands. The glass breaker and seatbelt cutters are great extras in case of emergencies.
There are reports of users that are unable to get an edge on the blade. It was fairly easy for me to get a great polished edge on mine. Using proper techniques will ensure a keen edge.
The blade doesn't keep an edge for as long as others, and i have chipped it twice. That being said it was simple to sharpen out. The soft metal was probably made with more chrome than normal to avoid rusting. This will allow for a sharper edge (if done properly) but means it will wear faster.
Over all, this is a superb tool and I highly recommend this to anybody looking for a sizeable knife with multiple uses.
