shim nYou'd have what we used to call a shim, something like a slice, cut straight on the top side an' roundin' on the lower side - it would come right up to an edge, an' kind of a handle on it, say, about eight or nine inches long. You take that an' you shove it, with the sap in the tree, you'd shove it around the rine, an' the rine'd all cleave off o' the tree.YesDNE-cit J.D.A.WIDDOWSONUsed I and SupUsed I and Sup1Used Ishem, Shin, MUNDLE, SLICE, wedge.The source is listed as T 36/8-64 in DNE
