From US based CulinaryCookware (http://www.culinarycookware.com/) for cutting curds I ordered their longest spatula. It is Matfer Bourgeat brand 350 mm/13-3/4" long blade (http://www.culinarycookware.com/spatula-sold-individually.html) for USD10.53 plus shipping.
Previously I had been using our household long serrated bread knife, but as I want to make larger batches of cheese, it would not be long enough.
Mine actually measures 353 mm/13-7/8" long blade. The only problem with it is it's too rounded on end so when cutting, I will not be able to get all the way into the edges of my stockpot vat. Needs to be more sword shaped.
It's a conditors spatula, the same type as mine.
Now you have a good curd cutter. The rounded edge won't scratch the vat's bottom.
Enjoy it!
I just received a spatula like that from Amazon. It has in addition a serrated type blade on one side... so I can cut (fatuous with that wide flat blade unless the substance is thin or very soft).
I just tried my spatula that I had lying in my kitchenware drawer and I think it was too thick. It did cut the curds but it was not nearly as easy as with a knife. They didn't cut as cleanly and tried to spin around the pot when I cut them. This one was 0.6mm thick. I'm back to the good old sharp-pointed knife for now.
Riha, this one cut the curds fine for me, not sure how thick it is as I don't have a gauge. My curds are generraly still "attached" to the wall of the stockpot so I don't have that. I've had my uncut curd pull away once before as it was shrinking but I thought that was too long before cutting the curd. That said I'm still using the Clean Break check method (https://cheeseforum.org/Making/Curd%20-%20When%20To%20Cut.htm) not the Flocculation Method to test for when to cut, so maybe my time when cut is off.
Just posted picture of it here (https://cheeseforum.org/forum/index.php/topic,2177.0.html) in my also new 40 US quart / 38 liter stockpot-vat to give it scale.
ONe of these days I will order a new spatula mine has a bend in the handle end and meses up my top layer of curds sometimes but it was only $1.69 at the dollar store.
Wilton's long cake spatulas are very nice, but cost a little.
