Someone correct me if I"m wrong. I don't think the concern is degloving so much as it is having your pinky or ring finger fractured. The trade-off is the knife is less likely to be dropped or taken away from you.
(And in some cases, like the SOPC, the ring is an aid in drawing the knife which is - as I understand it - designed to be worn on a plate carrier and could be more easily grabbed by your foe if it wasn't sheathed so deeply. This doesn't apply to the Ronin knife.)
