Have had a couple editions of the same knife. Minor differences with gimping, button size, recessed access to button, G10 texture... Oddly, they have the same serial number. This knife is clearly very friendly to a fidgeter, and about every deployment method does so effectively. Also an excellent blade shape. The XL exclusive has taken the best of the attributes and reconsiderations in design amidst the variants and applied them to this edition, replaced the flat grind with a beautiful hollow grind, in a steel that is known to have supreme edge retention and remarkable toughness, which is an asset to the hollow grind, and just a high end, proven tool steel in general. The action is noticeably improved, for all deployment methods in comparison to the others I have. I love flippers, and not a huge fan of front flippers or cutouts being the only means of deployment. Ideally a standard, flipper, button, thumb disc/studs, axis lock, or any combination of these it's ideal, and for me, this makes a front flipper just some icing on the cake. If it serves as an auto pocket deployment method, that's a huge bonus. And you can achieve that with this guy with some practice, as it's not a prominent front flipper. The gimping they chose to use to use on this one helps to facilitate that. Best feature would be the X L. So many mini variants, I would far rather see the opposite. Maybe some coating could have helped with the corrosion resistance for a tool steel, but my WMK Mini Critical it's shockingly bereft if corrosion or any staining despite some neglect after heavier use. And I am just a fan of coated blades in general, but minor, whiny nitpicking. But, what an excellent improvement on a great design, excellent service, excellent price synonymous with Justin and WMK. Would love to see more XL and maybe XXL WMK exclusives, the new Begleiter button lock XLs are grand slams on the way. Might have been the most fidget fury I've encountered. But we're taking about the Cormorant XL. It's a serious, capable, solid midsize blade with excellent steel, geometry no blade play, no stick and sharp as the devil out the box. And it becomes an addictive big boy toy and dexterity improvement device when not in use. No brainer. And truly, the action and detent are remarkable. Think anybody would be gratefully shocked as to how impressive the button lock functions, maybe the best I've experienced thus far, and I seek and collect button locks, at various price ranges. No brainer buy
