ratcheting mechanism on Spanish Navajas

Chris, I do not disagree that that there could be a legal element involved in this matter, and if this is the case then those with an interest in this subject should be able to carry out the requisite research to establish precisely what the law and attached regulations and definitions were. After all, we're dealing with a European power here surely the sources are there to be found.

If a legal element is involved, the whole matter becomes much more interesting.

However, considered in light of what is actually known about this knife form, what we do have in front of us is a reasonably simple engineering problem that was solved by a reasonably simple engineering application. Perhaps that engineering solution was applied because of some presently unknown, or at least indefinite, legal requirements, perhaps it was applied because users got sick of losing fingers. But there is no doubt at all that the ratchet does serve an engineering based function.

As you point out, the noise hypothesis is rather dubious.

The legal requirement hypothesis is very spongy and seems to rely on unauthenticated hearsay.

The risk control hypothesis is at least demonstrably practical.

I've got no stake in this matter at all, somewhere between little interest and no interest at all in navajas, and precious little knowledge of any of the cultural background. One could say I'm on the outside looking in, and what I see through the window is a tool (weapons are tools made for killing) that originally had a design defect that was remedied by application of engineering principles.
Perhaps there is a legal element that needs to be researched, but right now that relevant data does not seem to be available. When it does become available and legal or social reasons can be effectively argued, I might well change my mind, but right now all I can see is plain old fashioned practicality and common sense:- the blade flops open : lets fix it.
