I love the E4 handle so I'm especially excited about the Salt 1 style coming to the new Pacific. The Salt 1 is a little lighter and doesn't feel like it loses much, if anything, by being linerless over the D4.
And with respect to PE H1 edge holding, I've posted this before but here's my PacSalt after cutting ~200 feet (took about 30 minutes!) of thick, gritty bike-box cardboard. Still cut well enough, and it would barely shave with some moderate pressure. Touch up back to hair-poppin' sharp was 1-2 minutes on my 11" Norton fine. Really a great steel that has come to be much more appreciated by afis over the years.
I think I've got a half-dozen Pacifics at this point. It was my first Spyderco back 15+ years ago and remains my favorite folder. Excited to make it a full dozen between the new H1 and LC200N models
