Really nice, very heavy duty shears. Same construction quality one can expect from tools made by Schollhorn.
William Bernard sold the patent for his parallel-action pliers to the William Schollhorn Co., eventually becoming a partner in the company. Sargent bought Schollhorn in 1948, and are still around in name, they themselves bought out, then that company bought out, then that company bought out.
These shears aren’t marked Sargent, so I guess they’re from before 1948.
