Since you are wondering, what I am doing is cutting, collecting chasing after, and just enjoying my love for knives. And yes this little knife is a bit cumbersome in hand like I posted earlier the reason is my grip and I might have to modify it. As far as need and want I think if we are to think in these terms then only one knife is needed. As far as knife size if a knife is uncomfortable in hand then IMO you need another size kinda like a pair of shoes as for grip if a knife tends to slip in use then IMO you need a better grip kinda like the tires on your car. Since I am a traditional knife collector I don't think I have "a hold-over from their foray into the modern knife mentality" As far as moderns that's an individual's preference and their right to set whatever criteria they want for deciding on a knife. As you say you prefer a smaller knife that's certainly your right and you should simply like what you like.
