I picked up one of these at the NYCKS this past weekend (Level 3). Obviously, it has not been subjected to real use yet, but in the casual "fondling" it has received, it has rock solid lock-up as good as my Sebenza and feels great in the hand. Eventually I might be interested in upgrading to the bronze washers. It needed a bit of Tuff-Glide in the pivot area, but is very slick opening now--a definite "keeper".
