1. A folding tool, comprising: a handle comprising a pair of spaced-apart left and right frames each having front and rear ends, wherein at least one of said frames includes a frame spline opening disposed at said front end thereof, said spline opening having an annular array of alternate spline teeth and spline slots formed thereon, an elongated tool blade having a body and a tang, said tool blade having a tang spline opening formed therein which defines an annular array of alternate spline teeth and spline slots identical to said spline opening; and a transversely-extending lock member including: a spring which urges said lock member towards said locked position, the spring being carried between said lock member and a side plate which covers said frame spline opening; wherein said tool blade is attached to said handle by said lock member such that when said lock member is in said released position, said tool blade is freely pivotable about said central shaft of said lock member, and when said lock member is in said locked position, said spline ring engages said tang spline opening such that said tool blade is retained in one of a plurality of predetermined angular positions relative to said handle.
