Modern materials are an improvement, I already agreed.
(How many of you do own a Loveless ?)
I'm sorry but in my humble opinion, the possibilities of new materials are often misused. For one great and simple SR type handle, how many Herbertz and Spydercos ? Of course, some great new shapes do appear; the opposite would be frightening, it would mean that we were more stupid than the ancients. Of course BG-42 is nice to have, provided you can sharpen it the day you need to, WHERE you need to.
If you want, take my post as a regret. I regret that with better materials, more freedom in shapes, more choice, we actually end up with customers (I do not say "makers"; they only answer to the market) choosing designs which, for ten times the price, are really not ten times better than the old ones. Many are worse. Some are better but they are desperately expensive and are eventually a small proportion of the production (even after you've thrown out all the knives which are not discussed at all in these forums)
You can overall take my post as an advice : try out an old design, be surprised by its convenience, and then you will be able to choose, if you wish, a modern design which represents progress instead of "happy ignorance" (don't take the word as an offense, it's the only one I found in my poor english to express what I would like).
