Try in SJPdP the Boutique du Pelerin. Ask if they sell Victorinox/Swiss Army knives in a contact email using this web.
You can write in English or French.

Furthermore in Bayonne there is a salespoint for Victorinox/Swiss Army knives at
Arteon, 11 rue Orbe

Good luck and Buen camino!

I recommend Victorinox or Wenger knives. From Wikipedia: "The Swiss Army knife is the best-known product by Victorinox. Originally the sole supplier, Victorinox has shared the contract with Wenger since 1908. A compromise between the two companies gave Victorinox the right to advertise as the Original Swiss Army Knife, while Wenger laid claim to the title of Genuine Swiss Army Knife. Victorinox took over Wenger in 2005."

The Swiss Army officier's knife had the cork-screw. The enlisted man's knife did not. I don't know if this is still the case. Anyway, get the cork screw with the knife and be a camino hero to those who don't have one.

My knife is much like the one Victorinox calls the Climber. A medium and small blade (since the small is used rarely it will likely be sharp when you do need a sharp blade), a can opener, bottle opener, screwdrivers, awl, corkscrew, scissors and a few small things not needed.

I just thought of something so I edited my original post to add this: If you can't take your current knife to Spain then you probably can't take the new knife back with you so you may actually want a cheaper knife. The Caminoteca store near the cathedral in Pamplona sells a souvenir knife cheaply with most of the things you would want.

I purchased a Swiss Army knife in SJPDP as I left mine at home. I am mailing home at the end of the journey. It hasa Camino symbol on it. It will be one of my treasures.
