Having thus described my invention, I claim, and desire to secure by Letters Patent of the United States, the following:

2. A pruning device comprising a pair of blades having frictional engaging faces, each 'of said blades having an opening therethrough and terminating in its frictionface, a pintle member extending through said openings, one of said blades having a plurallty of grooves on its friction face radiating o'utwardly from the opening therein, said pintle having a bore therein and an orifice leading from said bore through the wall of the pintle and in the plane of the grooves in the blade,
and a lubricant in said bore.
In testimony whereof I hereunto afiix my signature. I
