Claim:
1. A firearm hammer spring removal and installation kit comprising: a spring spoon, a spring retainer, said spring retainer comprising: a channel having a left and right substantially acute triangular blades substantially parallel to each other; the unitary region between said blades being a substantially rectangular backbone; said blades oriented similarly on said backbone; said blades defining an inner area between them; the region of the spring retainer where said blades join said backbone being substantially similar to side A of a right triangle; The region of the spring retainer proximal to side B of the triangle being the lower portion of the spring retainer; the region opposite the lower portion being the upper portion; the region of said blades opposite said backbone defining a spring hook; said spring hooks being distal from said backbone and being substantially rectilinear tabs extending downward from side B; said spring hooks forming an open top channel extending outward from said blades; said lower region of said blades proximal to said backbone defining a semicircular spring saddle; said blades region between said backbone and said spring hooks defining a first and second plane, said first plane proximal to said backbone of said left blade being substantially parallel to the similar plane of said right blade, said second planes being distal to said backbone being converging toward said inner area, said spring hooks being substantially within said first plane; said spring spoon comprising: a shaft having a length, thickness, width and opposite ends; a first end defining a conical spring control cavity whose axis is substantially ninety degrees to the said length and its opening diameter is substantially equal to said thickness, and further defining a cylinder apex, both center lines being axial whose entry is the apex of said conical cavity, together their total depth being less than said width, and first said end further defining a radius radiating from the center of said control cavity substantially equal to one half said thickness defining a keen edge proximal to said conical spring control cavity.
