Yep, at work I'm the knife guy.
I do 12hr night shifts twice a week, a boiler operator stuck in a control room most of the time, so the WE lives in my locker and that's where the sharpening happens. There's about 30 people on a night shift, 70 on days, and they all know where to get their knives sharpened.
I'm cool with it, a lot of the them are fisho's, boat and beach, including a charter operator, pig hunters too, quite a few farmers or small block owners that do mutton and beef homekills, people who really use their cutting tools and appreciate a good edge.
I charge $5 - $10 a knife, mainly 'cos if I didn't there'd be a never ending queue. And it's paid for some stones and a WE upgrade kit over the past few years.
I keep some decent cheapo chinese folders in my locker for sale, and a few good folders for people to see. Usually its the cheapie's that sell, occasionally someone wants a Spyderco, but the exchange rate makes them expensive over here.
There's quite a few people at work with an EDC folder now, that wonder how they ever got by before without one
On BF I'm a greenhorn compared to many here, but to my coworkers I am 'The Knife Guy'. Bless them.
