Even though it does not have a pocket clip and is not one-hand opening, I do not consider the Roadie to be a traditional pocket knife. It does not look like any traditional pattern with which I am familiar. On a timeline, "Traditional" patterns are patterns that no one would have considered odd in the 1960's.
And the Lucky, while it looks like a traditional pattern, has a pocket clip.
I will make the comment that N690 holds an edge a tad better than 154CM / ATS34 / VG 10.
It holds an edge less well than PM alloys such as S30V.
If somebody can show me a fifty-year old knife that looks like the Roadie, we can proceed.
