Tech companies cover up their hard edges with a wide range of dubious management techniques.
科技公司用各种不太可靠的管理方法来掩盖我们的硬心肠。
问题：
请问edge可翻译成心肠的意思？在每个字典中都找不到相近意思。
Tech companies cover up their hard edges with a wide range of dubious management techniques.
hard edges 是依据具体语境翻译的，“坚硬的边缘”比喻“生硬的待人方法”，还可比喻“矛盾”。比如：
But the simple repetition of cooking and eating brings the family together, softening the hard edges like boiling water on rice.
不过烹调和用餐的简单惯例能让一家人聚在一块，软化矛盾，就像沸水煮大米一样。
