[2] The wrist-guards are small rectangles of stone (often slate) with a number of perforations, typically between two and six, which might allow attachment to the arm with cord.
The shapes of the wrist-guard are stereotyped, and common forms exhibit a narrowed 'waist' and curved cross-section (presumably so they fit the arm better).
Stone wrist-guards are exclusively found in the graves of males, frequently lying next to the body's wrist.
They may have been status symbols of prowess in hunting or war, possibly mounted as decorations on functional bracers.
However, one at least (from Barnack in Cambridgeshire) had eighteen holes and each one was filled with a foil-thin disc of gold;[7] these caps would have prohibited any form of rivet or cord being used as a means of attachment.
