Chen improved upon the Wu Hook by modifying the length and giving it a very flexible blade that made the weapon easier to wield. He also added some nice aesthetic touches, gilding the mouth of the scabbard and the scabbard protector. His efforts won him an ROC Consumers 'Association Award of Excellence for 1996.
吳鉤刀經陳天陽改良，長短適中，刃質富彈性，揮舞自如，再飾以鎏金鞘口與劍鏢，在一九九六年獲得中華民國消費者協會精英獎。
