Which is the most durable wooden brain teaser available online?

[AllenSpoig]

Hi all, I've been trying to find a few quality gift ideas lately. I came across a few classic puzzles by small workshops. I'm trying to figure out how to find rare custom sets these days.
 
Furthermore, does anyone know which these craft puzzles or which designs are most durable? I really liked the artisan finish. If you know where can I buy these custom sets, I would appreciate the advice!
