This handle and one tool are all a beginner piano tuner or a do it your self person really need for simple upright action regulation. The idea here is to save money, and use the key spacer as a sub for several functions. The full kit is great but this one will do for now. Since you will have the handle that holds all of the tools, just buy what you need later. If you are not really on a budget then go ahead and get the full UPRIGHT PIANO REGULATING TOOL KIT. SPECIAL OFFER FOR HANDLE & KEYSPACER: SHIPPING INCLUDED!
