(b)(4).The sample was returned for evaluation.A visual exam was performed and some metal displacement was noted in the blade ball bearing cutouts.This metal displacement appears to be the result of normal usage, day to day blade engagement and disengagement.In order to attempt replication of the reported defect, three (3) blades were attached to the reported defect handle.The blades used were: emerald mac 3.5, reusable (product code 004433500), rusch green lite miller 4, disposable (product code 004550004), and emerald mac 1, reusable (product code 004431100).All of these blades attached, engaged, disengaged, and detached multiple times without any problems.A review of the attached dhr/inspection record did not reflect any issues related to manufacturing activities.Based on the investigation performed, the reported complaint could not be confirmed.There were no issues found with the returned sample.
