<u>Product Description</u>

<b><u>Certi-Split&#174; Red Cedar Shakes</u></b>

[[File:7.2.1.2.jpg]]

<u>NO. 1 HANDSPLIT & RESAWN</u>
:These shakes have split faces and sawn backs. Cedar logs are first cut into desired lengths. Blanks or boards of proper thickness are split and then run diagonally through a bandsaw to produce two tapered shakes from each blank. 

<u>NO. 1 TAPERSPLIT </u>
:Produced largely by hand, using a sharp-bladed steel froe and a mallet. The natural shingle-like taper is achieved by reversing the block, end-for-end, with each split. 

<u>NO. 1 STRAIGHTSPLIT</u>
:Produced by machine or in the same manner as tapersplit shakes except that, by splitting from the same end of the block, the shakes acquire the same thickness throughout.

<u>NO. 1 CERTI-SAWN&#8482;</u>
:These shakes are sawn both sides.
