I always carry a knife unless in a metal detector secured area.
The one I have is a Kershaw Speedsafe Oh So Sweet model. It is spring assisted opening and with a liner-lock. The blade is concave with a smooth edge to assist in sharpening. I use a diamond hone to get and keep it razor sharp. I am very careful with it because it is sharp enough to take a finger off. I am confident it will cut through clothing and to the bone in one attempt. It has a lifetime warranty that I used it once when the original knife had the spring backbone break. It is made in China (quality is always suspect) and probably why the backbone snapped. Kershaw had the replacement on backorder for about 2 months. But the lifetime warranty for about $20 outlay has been worth every penny. With the attached side clip I keep it at the top of my front pocket and can one-hand deploy it about as quick as a sidearm draw.
