I'd like to re-state what others have emphasized: The RANGE of Traditional non locking knives is still astounding: a vast spectrum of blades, sizes,types and numbers,handle materials make them VERY appealing.Plus,craftsmanship and skill in making them gives pride of ownership most certainly. They are very individual and slice superbly when well sharpened additionally, they are very beautiful not just to look at but to handle.As time passes they get better too,age and patina/mellowing in colour augment the appeal.
As for stainless v carbon, I frankly like both. Carbon get's patina but does need a bit of attention,stainless works better in my view for food prep as it imparts no taste. I do understand your hesitation about bone, to modern knife owners it might seem bizarre,barbaric and possibly un hygenic....but the cattle were eaten for food and the shin bones re-cycled as something beautiful and useful.The animals were not hunted to death for their bones (same with stag hopefully as they shed antlers naturally,they are good meat providers too!) I have reservations about using tusks,teeth or bones from rare or endangered species,hunting them down just to make artefacts is out of the question and should be stopped.
Worthwhile ,companies include CASE(much improved in the last few years) Queen Cutlery, Schatt&Morgan,Great Eastern(some good liner locks there) Böker, Hen&Rooster.
If you want to test the waters with slipjoints and don't want to whack out a lot of cash on patterns you may not like then I suggest trying some Rough Rider knives first. Users they are. They are cheap to buy and not at all bad in quality,yes they are Chinese made and yes they ARE surprisingly good and I am not making political points here one way or many others so, potential flamethrowers please keep cool . Not a bad way to experiment before buying costlier authentic cutlery.
I tell you this, once you buy a couple of Traditionals,you won't abandon the genre, you'll be back for more!
