Question

Although Julian had spent three years under Master Kenji’s tutelage, their workshop was rarely filled with words. Kenji would set a block of cherry wood on the workbench, tap it once with his mallet, and walk away. To an outsider, this silence might have seemed cold, even dismissive. But to Julian, each silent gesture was a precise instruction. The single tap indicated the wood’s grain was uneven, requiring a lighter touch with the chisel. Julian would adjust his grip, work steadily through the afternoon, and leave the finished piece on the shelf. The next morning, he would find the piece gone, replaced by a fresh block and a slightly sharper chisel left near his workspace. No praise was ever spoken, yet the presence of the sharper tool—reserved only for those who had mastered the basic cuts—was the only validation Julian needed to know his skills were advancing.

Based on the passage, what does Master Kenji’s placement of a sharper chisel on Julian’s workbench most strongly suggest about their professional relationship?
