1.) BM 585 - 154cm steel. But I'm not sure if you're looking for larger or small because this is the smaller one.
2.) BM Bone Collector - if you really want a nice gentlemanly folder, check out the Walnut one. These are D2 tool steel. Very good steel, takes a nice edge and holds it well too.
BM 530 comes to mind as small, pocketable, people friendly, gentlemanly and just nice.
BM's H&K line of knives are actually really good, especially for the money, I've owned several and have been very pleased.
Also Lone Wolf makes some really nice beautiful knives.
If I ever have a wedding, they're all getting a Spyderco.
I like the 530 plan on buying for myself some day. But i read that the handles feel too small. What do you guys think?
H&K usa made knife is also one i'm considering.
i read that the BM griptilian's poket clip combined with the grippy surface will wear a hole in your pocket.
they like camping and being outdoors so if the knife looks too gentlemanly they may not use it.
