I've had my Citadel for about a year now.
Having owned a number of auto openers over the years I have to say the Citadel is by far the best overall package to date.
Very comfortable in the hand - opening is fast enough and solid lock-up - thumb serration platform is perfect - the lock feature is easy to use and does the job - plain edge is very sharp out of the box - and easy to touch up - carry wise no drama - I appreciate the stout point.
