I have been doing some electrical work with my second Spyderco (bought like 20 years ago, Endura combo edge). Cutting tape, corrugated conduit (the kind that you install inside the walls), etc. I confess I have pried open a few pre-cut side opening in the boxes you install on walls...
The picture of prying open the lid on the paint ca in the first page of this thread n made me nervous... can't think of an easier way to snap the tip off of a full flat ground blade.
