I can't comment on the Chinook as I don't own that model yet, I do plan on getting 1 as my next Spydie purchase.
I can however tell you about the Lum.
I've got both models the, the green Lum in SE and the gun metal blue in PE.
Would I use them as EDC knives, NO where I think they fit in is a gents knife.
I sometimes wear mine to church functions, and have found that people tend to NOT consider this style a threat.
In fact not long ago I was in a gardening shop with my wife (being dragged kicking and screaming) :barf: looking for orential bonzia trees, up walks this elderly lady and notices the green Lum in my RF pocket.
Her comment was may I see that nice gardening knife, she loved it.
So that's a nice perk in my mind, having misinformed knife people become intrested in a safe looking knife.
Either model will serve you well, so follow your own thinking, OR! do what I do raid the bank account
