I better say I am biased here. I am a bit of a knife geek, if you must call it that. As an engineer and craftsman I really do appreciate having the right high quality tools. I have served my time using second hand kit, and cheaper items and when I have had the chance to upgrade, I have done so, and always found it to be an improvement.
I also better say that I am not a fan of the green Frost. It is good value, but it is a poor knife when compared with many similar knives, even with other Mora type knives. I saw 10 people on a course sustain more damage to their hands using those knives than resulted from all the other activities on the course. I can with great certainty say that the knives that I make are more efficient tools, and more comfortable, than the basic green handled Frost. That isn't because I am a great maker, just that it isn't hard to do better than those frosts if you put the time in.
The global environmental aspects aside, I think it a generally good thing that the human animal is always striving to improve the quality of their tools. I feel it would be a very dull world indeed if as a group we found the first thing that worked adequately, and stopped there.
I do agree though that many people mistake the aquisition of kit as a substitute for knowledge, particularly in bushcraft. If you are able to use basic tools and suceed, kudos to you. At the same time, I see no reason to deride anyone for enjoying the aquisition of kit, or for enjoying having premium tools rather than those that would be merely adequate. To each his own.
