WMK, thank you, thank you, thank you for having both this and the brass cage ball lock available for my Spyderco Manix 2 XL. I've been looking for this item for so long and finally found that you have it available, and without hesitatation bought both the copper and brass Flytanium ball lock. Had it installed on my Manix 2 XL, and made a good knife into a great one, and no problems whatsoever. The action and feel of the new lock is perfect and looks good too. I recommend anyone who has a Manix 2 XL to upgrade the cage ball lock. Thanks again WMK, for having this item available and for fast shipping. I'm a happy customer!
