I bought quite a few from California Bonsai Studio when Colin Fraser was on here.
I have placed about 10 orders through here in the past few years.
https://www.j-bonsai.com/phone/ I found them to be professional and friendly. The prices are great when compared with other sources, like ebay, even with shipping. Payment was made by a paypal invoice. Once you add the items to the cart on the website and checkout, he’ll contact you with availability and cost within a few days. He’s even tracked down what is shown as currently unavailable, if possible, from a display case, etc. Once he has them in hand and they are shipped, they take less than a week to arrive. For me, they have arrived right in the mailbox by USPS, originating from DHL.
They have a few stainless shears, but most of the 8000 series tools are actually plated carbon steel, which to me is the best of both worlds.
The guy’s name is Maki Isano, and while it might take a couple emails back and forth to do the deal, it’s worth it to get what you want. Just DM me if you want his email address.
