Most. The hook that allows it to come apart is not that common. Charvet was the only one I knew of offhand.
Jpress was a good source but I now mostly buy from a local shop.
Btw, the hook shouldn't bother you. If well constructed, you won't notice it one way or the other. I can't comment on drakes as I haven't any, but the charvet hook doesn't make a difference to how I knot the tie.
