In the draWings,'I have shown. this ham-,1

In the form ot'Fig. 2, the handle includes; a shank por-- tion a of materially less cross sectional area 1 than the hook body projecting outwardly 1 from the body and disposed in the plane of the body,'and an elongated knob or portion 1 90 I) also of materiallyfless cross sectional area than the hook body projecting at right angles from the portion a, with the portion I), however, lying in theplaue of the body.

' Intho form of Fig. 4c, the portion (1 cor.
