ratcheting mechanism on Spanish Navajas

[fernando]

I went back to the pictures of a XVIII century Mudela navaja i once had. The picture quality is not so famous and the ratchet teeth are somehow worn but, might i make a point in that, once the blade accidently disengages from the main notch, are those little scoops that will prevent it from fully folding ... or are they no more than a noise carraca ?
