What is he thinking?

Ravina had to allow Mara to use the peeler for a while and try different vegetables before she could be happy with her inventions. 

"It works on all," Mara said happily. "And it is easy to use." 

Ravina nodded. She knew Mara was speaking in comparison to using a knife but Ravina wanted to know the details. "Is it slow? Do you feel like it glides smoothly or is the edge not sharp enough?" 

"It is not as sharp as a knife but it works. I am using more pressure," she said. 

Then she needed to make some changes. "How is the handle? Is it easy to hold or does it feel uncomfortable?" 

"I have no problem with it," she said but Ravina took her hand to see if there was pressure from the handle. Her skin sank in where the edge met, so a more comfortable handle was also needed so they could peel for a long time without suffering from pain. Even if they were dragons. She was inventing this for everyone.
