I do not own a criollo in damascus, in fact I have never owned any knife with a damascus blade.
I have no doubt however that the cuchillos criollos in Damascus are just as good, performance wise as the mono steel ones
Most of the best contemporary artisan cutlers in Argentina and Brazil are making really beautiful criollos with stunning intricate patterns.
I personally prefer the plain and simple carbon mono steel blades.
This is not because of performance reasons but rather out of my desire to follow the traditions of old gauchos as close as possible.
I even asked for a wooden handle from a native tree to Argentina and passed on the stunning and beautiful stabilized wood burl handles.
I also swore to never ever clean or flitz the patina of my Verijero
A patina would likely soon start to obscure the beauty of a Damascus blade so cleaning it may be required to make the pattern pop again.
And of course, the plain blades are more economical as well.
Having said all this

there is one Damascus pattern that has got me very excited as it checks all the aesthetic and beauty centers in my brain.
It is called “River of Fire” and is really incredible !!!
