a 210mm is 8.5 inches roughly so go with the larger size and cut it down if you need be.
If you wanted a better product I highly recommend the victorinox magnet ones, I got one of them at a local kitchen supply store and they work much better than the CKTG, although the ultimate in blade protection is a saya.
Do the magnet cover leave marks or scratch like plastic ones do?
