Tuning success

in my LOA 4 submission, the strut, David noticed my D harp had a flat 4 draw. Which I didn't realize and I was so surprised that he caught it. Professionalism at its best. So after watching your lessons on tuning I have attempted to tune that flat reed and to my surprise I successfully did it. So again thanks Kenya for all the efforts you put into your lessons and teaching in an easy to duplicate way for success. I don't have any of the correct tools you describe and mostly made due with a pocket knife and some jewellers screw drivers and my IPhone. So the gift to me from me for the level 4 accomplishment has to be to get a hohner kit. 

Thanks

John
