ratcheting mechanism on Spanish Navajas

[A. G. Maisey]

Thanks for your remarks Chris.

Obviously I'm not looking for any comments on the navajas I had +30 years ago. They are no longer in my possession, and I have no idea where they might be, I was only throwing an offhand comment into the discussion.

Yes, I've seen previous discussion on navajas, but I'm not really interested in pursuing the subject. I accept that you are expert in this subject, I admit that I am not, I can only comment in objective terms upon what I have seen.

A.G. Maisey:

I apologize if I sounded a bit censorious and I do not for a moment disbelieve what you say.

The original question by Richard was re the function of the ratchet, which originated in Spain quite early in the development of the navaja. In that context, we have to keep in mind the technical limitations that those cutlers were confronted by, and the role of the said ratchet in that historical setting.

What I mean by my remarks was that the justification for your experience has to be sought in the make, typology and age of your knives. Modern knives can do all sorts of things that the antiques could not and have no bearing on the original intent behind the ratchet.

As an aside, locking clasp knives of the Spanish pattern were made in many countries besides Spain, as afar as India and Africa, and many of these were way better than those of Hispanic make. The French in particular made very good `navajas' in the 19th century and these were eagerly imported into Spain in huge quantities.

The navajas I was talking about were all old ones, i recall one had a horn handle, and the horn was separating because of age and neglect. I had never thought of navajas as small folders until I read the remarks in this thread.

As I have said, I have no expert knowledge of navajas, and very little interest, but I do have a background in custom knifemaking and I was a member of the Australian Knifemakers Guild for about 12 years. My opinion of these knives as a maker is that they needed an effective method of locking the blade in place, and when these things first appeared it is unlikely that good spring steel was a practical application. I would guess that the very early ancestors of navajas were like a lot of early folders, no backspring, no locking mechanism. A lot of Italian folders are made like this even today.

The blade in a folder without a spring or locking mechanism can be made with an extension that comes down onto the back of the handle when the blade is open, and the hand holds the blade open, but this design is far from a secure lock. Probably when it became possible for small pieces of spring steel to be used the cheapest and most practical method was the notch on the back of the blade locking into a sprung catch. The ratchet would have followed this.

That's the way I look at it as a maker:- a simple, cheap, mechanical fix. Totally practical for somebody working with simple technology and tools.

Well, "small" is a relative term and I did qualify it by quoting Forton's 6"-9"range for average size.

Whilst they did come in all sizes, from very small to gigantic, my remarks were in relation to the big navajas that many collectors wrongly believe were meant for use.

With all this said, we are still no closer to knowing the intended function of the ratchet.

Here is a very well worn and nibbled upon navaja that I bought last year at the Brimfield flea market for $25. I have been using it to open envelopes. It is about 9½ inches long closed and the blade is about 7¼ inches long. It is loose enough now that you can close it without lifting the latch, but each ratchet point does engage and give some resistance. Put your thumb over the latch and fingers naturally around the horn scales and the blade is securely open. I prefer this design to the pull ring clasp style that was reputedly derived from it. I'd welcome any comments as to how long this old knife may have been around.

Yeah, you're right Chris.

Intended function of ratchet?

Prevents accidental closure of blade.

An excelent example Lee; a genuine one for an amazing price. I guess the pull ring clasp version ended up giving place to the 'the last of mohicans' of these mechanisms; one certainly made for purposes more directed to tourists other than villagers. Another system was that like the one of your example but with a lever to easier operate the opening. This was the system that i got used to see around since my youth; the main weakness was that the lever was rather feeble and worn out very quickly.
