For over a year I've been carrying a cheap Bar Creek rosewood inlaid 2 inch blade lockback that I bought at Wal-Mart for about five bucks. I widened the holes in it so I could put it on a half inch key ring, and attached it to the lanyard of my MagLite Solitaire. At the other end are my keys and my whistle/led flashlight. I put a good sharp edge on the Bar Creek blade and find that I use it several times a day. The incredibly sharp bayonet style tip is quite useful, and overall, I find a mini lockback to be very handy. Works for me. Regards, Keys
