This key is yet another long high leverage type but this time I've swept back the handle by slotting the heavy front of the arm and inserting a thinner arm at an angle, I'm using square heavy chucky brass for most of the components, with a crush tightener bridge as the gap adjustment, after using this key for a while and loaning it out for evaluation the general feeling was it was a bit tail heavy so I have drilled a series of holes in the swept back arm and the main body to the rear of the pivot point, this has had the effect of reducing the tail weight and lightening the action, all part of experimenting with key design,  time to decide on the terminals, either small ones fitted to the key itself or large ones on the front of the wooden base
