I have a vague recollection as a kid of reading an article in (I think) Blade where Bob Loveless (or one of the other popular bladesmiths of the day) said that, if he were working around docks all day, cutting rope and such, he'd carry a serrated Worker knife from a newer company called Spyderco. I thought this odd and, when I later saw a picture of the knife, even odder. What a gimmick, I thought at the time.
Well, years went by and I was living in Europe. An American buddy and I got to talking about knives in a pub. He pulled out a stainless serrated Worker and a stainless plain-edged Police. These things are AWESOME, I thought. Rock solid materials and construction, and you could carry either (or BOTH) easily accessible, without them clunking around at the bottom of your pocket. For years my "big knife" was a beat up Schrade LB7 but I'd quit carrying it because it was so heavy and bulky. After seeing my buddy's Spydies up close I did a little research, hitting all the cutlery shops in town and buying a copy of Tactical Knives. It wasn't until I moved home to the States that I finally picked up a 50/50 Delica. Got a lot of use out of it but eventually traded it off and picked up a plain-edged Endura. Use it all the time.
