jambe

Crest - A jambe, unarmed, excepting the spur, quarterly, or and sa.

[…] cuissarts or cuisses were used to shield the thigh, and boots of steel called greaves or jambes were worn upon the leg between the ancle and the knee. We have no doubt that the jambes were found to act well as preserves, but we think at times the shin must have been sadly jammed in them.
