You got that right Alvin, thought that was my own discovery.
Whenever I cut, I run my thumb over the jaws and a few times
if I'm making a long cut. And, same as you, they cut like new.
I always credited it to the fact that there is a little oil
left on the jaw by my thumb and that was why they cut so nice
I still use my first set of Malco snips that I got the first
day of my apprenticeship. The boss took me with him to G. W. Berkheimer's
when he was picking up a furnace and fittings that morning. He
filled up a cardboard box with what tools I would need and
said he'd take a little out of each pay envelope till they
were paid for. I stopped at the local Sears & Roebuck store in
Downers Grove that evening and got a tin box to keep them in.
Still got the box and the original tools also. I have added
some Wiss snipps and other stuff over the years:http://www.pbase.com/dennygraham/image/160048749/large
