Nice handle unfortunately the thread pitch is something to consider. I have the La Spaziala Vivaldi S1 and the threads are M12 1.25 pitch. This handle will not thread into the La Spaziala portafilter. I took the handle to my shop and rethreaded it. Also the wood handle must be dry at all times after washing. The handle started to show water damage. To fix that I used a Satan Clear coat for wood finishes that will repel any water that will be in contact with the wood handle. Some work was needed. Now it’s completed and life is good now 😉
