I posted these pics of my snath wrenches on the old site. Still have them on photobucket.
The first two are the wrenches I have with no two exactly alike, all eligible for the under 4" club. I think I have only added one since I took these pictures.
The last two photos are of my salesman sample scythe handle with the snath and the attached wrench.

The earliest patent I can find showing a scythe-snatch wrench is No. 144 issued on March 11, 1837. No. 7 in the patent drawing is the wrench.

A more conventional scythe-snatch wrench is shown in an "Improvement in Scythe-Snatchs" Jan 9, 1900 patent. I suppose there are numerous other snatch patents.
