I appear to have wrecked 2 ratchet blades when getting rid of collected debris. After re-assembling I am unable to adjust the blade depth, no matter what I do I cannot release it to adjust. Obviously I've done something wrong when exposing the blade but I've no idea what. These blades are not cheap and I'm reluctant to replace them when I believe the blades themselves to be undamaged. Has anyone else had this problem or am I the only ham fisted one? Be grateful for any suggestions to help solve my problem.
