Well, with that said, sometimes you DO need to add a new variant to the pliers drawer in your daily working toolbox.
Up for your consideration is a Berylco set of slip joints. Conveniently picked up on the sly while routing around a scarce collection of tools at the local thrift shop annual sale. What a madhouse that corner of the store was with old codgers (me included) competing for non-valuable tools in the man-cave corner. Since I was there 3 hours after the sale started, that told me these non-sparking slip joints,"slipped" past the scrutiny of those less burdened with the trivial knowledge of specialty tools disguised as ordinary tools.
Next up, I present some odd Proto slip joint pliers. Found at some garage sale while out pedaling, these HAD to come home with me for .50c. Made in Canada no less, they appear to have had almost no use, and adjust to not just 2, but 3 slip settings.
Do I need any of these? Uhhhh...NO! Will I use any of these? Uhhhh...perhaps. Did they scratch some sort of tool collecting itch? Hell yeah!
Have a great tool-finding day!
