I report that all backsprings survived, rule of thumb - open slow, close gently. Appreciate the defining of OP, can always use help.
I call 305 as "Sunday Knives" . But, that has faded away in this suit-less world. I am not a suit guy, but I appreciate those that have to wear them in there work. I was lucky, I wore a uniform and usually rubber boots and smelled of mud. So bigger knife for me. 300

 

Guilty as charged! If I like a knife enough to depend on it, then I want more than one or two back-ups. OH
