I'm sure this has been covered in the past, but I felt an updated survey couldn't hurt. Be sure to participate in the poll. Do you carry a pocket knife? When? Where? Maybe most important question of all, what kind?
I've had my share of them, from the cheap one's I had in my tackle box as a kid to pretty decent knives as an adult. I've had Case and Old Timers, but now I prefer my made in the USA Buck. It's the Buck Knives 303A--a medium sized traditional folding pocket knife. It features 3 stainless steel blades, a 2-5/8" clip point, a 1-3/4" spey, and a 1-3/4" sheepsfoot. It is 3-1/4" long closed and weighs about 2 ounces. Mine has black plastic handles with the Buck logo, and has Buck's Lifetime Warranty. It seems to maintain a keen edge for all my needs. I bought it from Amazon about 3 years ago, right after I lost my Old Timer. Naturally, I found my lost knife the day after the Buck arrived. I usually have it in my pocket, but there are exceptions--usually when required by law.
