My EDC. 40 years of reaming copper tubing, scraping gaskets, stripping wire, tightening screws, taking things apart and putting them together. Oh and cutting stuff too. Nuttin fancy and didn't cost $300 so I wouldn't have been devastated if I lost it when I worked for a living. But would be now as it's retired to the top draw of my tool box. An original Imperial electrician knife like it I've seen go for as much as $12 on Ebay!
