Handcrafted wood spatulas are the best!   
Why a round spatula?  When you do kintsugi repair, filling in cracks on CONCAVE surface, such as the inside of a bowl, you will be glad to have this spatula. It's gives you effortless clean application, especially for those who are frustrated about have surplus sabi all over the non-repairing area ;-p
 
The width is about 25mm. We shaped the spatula so that you can have 2 different rounded profiles for different curve surface. And with some sand paper, you can customize and reshape the corners it to your needs.  
 
Good quality, functional-size spatulas tailored for kintugi-use is hard to come by.  Oak is very durable and will last you a lifetime.  
 
Each one is handmade by our artisan Kai using Japanese oak.  Over time, the tools will age and patine from all your practices using oil and urushi lacquer.  (That's one of the reason why I love wood tools).   You won't find wood spatula like these in any store.
