I have it, and it's a very Wide Knife, Pretty Comfortable in use, But Big and heavy for the blade size in the pocket. I like Elmax on other Knives, but since it's a recurve, it's harder to sharpen for me so I would have rather had a softer steel. I would honestly Prefer 154cm to my Elmax (I know it comes in S30). But it's cool to have an Elmax, and It's a great cutter, if you are good at sharpening, or you don't plan on sharpening it, I would go for the Elmax.
I generally dont use the Flipper because of the Jimping on the handle scratches up my finger, but the thumb stud works great for me, very easy acces, and I think it opens faster with the stud.
Nice Pocket clip, carries deep.
Pretty Ergonomic Nice knife, but although it's smaller than lots of the other ZT knives, they are much bigger than most other brand knives, but I love them.
