My JYDII CB's, including a blem in grey G10 with the smaller JYD's fuselage pattern, work quite well - opening with a good 'thunk'. A more polite - but bank-vault inspiring- 'clunk' is heard from the easier to open Ti framelock SG2 variants, one also a blem. No JYD's here now, but it is a nice knife. The Ti/SG2 blemished JYDII, the only way that version seems to be available now, is a great bargain. Very well made knife, despite the poorly centered lamination. Mine came second only to my original production version in being my sharpest 'out of the box' new knives.
If you have never touched a Kershaw, even a basic CB (CPM-D2 edge) JYDII will shock and spoil you... be forewarned! Solid flipper - just start with inward pressure before pulling the flipper back smartly.
