The Tighe Pan is a liner lock. I have had two. Overall quality and finish is leagues ahead of the Buck Mayo. As has been said many times, put a Lone Wolf Tighe and a Brian Tighe custom side by side and you will have a hard time telling the difference. Don't know about the Dominator, but I have had a Maxx - and again, the quality is in different classes.
Blade shape of the Tighe is long and lean - very pretty and makes a great letter opener, but as far as EDC goes, perhaps it is a bit limited. It is thin and light and solid - very easy to carry. The grips design is excellent, good expansion of the grips front and back. I can't really compare the S30V heat treat - as I never really really found a place in any real cutting duties - and perhaps that's the reason it is being dumped by Lone Wolf - just how many folks (knife knuts) want a high quality letter opener?
My primary criticism of the Tighe is that the thumb stud is rather poorly designed. It is an inverted cone shape, narrow at the blade and fat at the top. I personally never found the blade easy to open, regardless of adjusting the pivot tension to a minimum.
