Riley对Dezeen的记者说：“我的工作室需要大量制作手工学习模型 。 长时间的使用裁刀后 ， 我出现了最糟糕的手抽筋 ， 于是我开始思考如何改善工作流程 。 ”

他继续说：“我开始设计一把手柄 ， 来解决使用中的最大问题：伸出的指关节 ， 这是痛苦的来源 。 关节在长期压力下变得难以忍受 ， 所以我就从这里迈出第一步的 。 ”

"My studio required immense amounts of study models that had to be made by hand" Riley told Dezeen. "After spending hundreds of hours using pen knives and having some of the worst hand cramps I started thinking about how I could improve work flow."

"I started designing a handle that tackled the biggest problem: hyper-extending knuckle joints that's where the most pain was coming from" he continued. "Prolonged pressure on a single joint becomes unbearable so that was where I started."
