Having perfected what I like to think is an excellent action key relatively easily as in Key 070 and 080 I'm going to play with the design a bit, keeping the dimensions more or less the same but using a simplified ball bearing arrangement and a more tubular look by using a heavy brass bar as the central bearing block and perhaps shift some of the weighting towards the handle, this time I've put a bit more into the adjustment, with spring loaded contact spacing, it is a lovely key, heavy but the long handle and hard spring balanced against the weight give it great action.
