Wow, A interesting question from across the ocean and memories stirred by others comments. Like some of you my 60yr old hunk of bone an flesh lived thru a childhood of riding bikes far from home, bb guns carried across the handle bars, chemistry sets where we tried to make rocket fuel or explosives. If we wanted to get high we climbed a taller tree. And yes we stood in the back of pickup trucks and rode down the highway. The fourth of July was cause celebrate', Black cats (firecracker of choice) were stuffed in and under all sorts of things and we even grew to have patience to cut them apart and collect gun powder to make pipe bombs. But, not to worry all we did was stuff newspaper in each end and used the pipe over an over. I laugh when we talk about this now and then comment I am like a cat, I have had nine lives. Between almost drowning twice, all the bike wrecks, boat accidents, electrical shocks, whacks in the head, dealing with people who were carrying guns, I think I am on life number 7 or 71/2.
To the OP, my outlook on Buck knives is that "this ain't rocket science". A inexpensive plastic handled knife is just what you pay for. If you are going to be James Bond you need to get a Buck that is metal and wood. The plastic handles have a very reasonable expectation of standing up to normal wear and tear. If you are going to use one to cut logging cables, ship hawser, pry on steel girders 500 ft in the air and or slice off a farm tractor tire from the rim, use something better suited for the purpose. The bantams are inexpensive, lightweight, are light in the pocket and commonly available in the US. They are designed to meet the cutting needs of a modern day man. Torture tests do not apply to this category of Buck knife. The lock must be reasonably safe. Reasonable is defined by Webster as "fair, sensible, moderate".
While it might be a un-holy act for many on this forum, I suppose if you give me a dozen or so 110s I can devise some fiendish way of making them all fail eventually also. Attempts to make a inexpensive knife fail is not useable information, failure during common actions is newsworthy and we welcome those discussions. Just my opinion.
