Having a conversation with David Steri about building a small Dorgalese. He says ~
"Con questa modello (Dorgalese) il problema è che se riduco troppo le misure , ci sarà un problema di robustezza del coltello stesso , se guardi la posizione dei perni ci sono degli spazi da rispettare sia per il buon funzionamento , sia per la linea che diventerebbe troppo tozza e magari sgraziata ...
Il modello Pattada o Arbus hanno degli spazi di lavoro più comodi e la riduzione può avvenire senza stravolgere la linea e la funzionalità ."
Which we all know to means ~
"With this model ( Dorgalese) the problem is that if I reduce the measurements too much, there will be a problem of sturdiness of the knife itself, if you look at the position of the pins there are spaces to be respected both for good functioning and for the line that would become too squat and maybe awkward ...
The Pattada or Arbus model have more comfortable work spaces and the reduction can take place without upsetting the line and functionality."
I must admit - to your point Charlie,
waynorth
- I can't see it.

Even with Davide saying so I'm a dunce to understand. I can readily see that the differences of the Arbus model but of the Pattada and the Dorgalese, even though I have a model of each in hand, I cannot see the difference - other than the earlier mentioned slanted bolster of the Dorgalese. The stop of the folded blade on the smaller Pattada is deeper than the that of the Dorgalese but there is no obvious difference when the blades are open. Both have the offset pivot pin as described by
Âchillepattada
.
Still - I must say that the Dorgalese -
somehow - seems more elegant.
Will someone please unveil this mystery for us -
Âchillepattada
? J-M, what are the physical/mechanical differences between these two Sardinian knife traditions? Maybe Davide will be willing and able to explain more.
EDIT - This just in from Davide Steri ~
"This of Gigi has another yet different form, each cutler has his own variant in fact. Tomorrow I will send you some photos of the templates in order to better understand what I mean, we are talking about 5/7 decree mi of mm, which however would not close the blade or could not act as a wire guard .... tomorrow I will take photos."
So - good. Class will continue tomorrow!
