saw sharpening shops are getting to be harder and harder to find. in our disposable society most folk are to either to busy or lazy or stupid or cheap to bother. sharpening cheap blades, well, do I need to elaborate ?
keep one thing in mind, if you don't support local sharpening shops then your future option just might be either ship out (like with forrest blades) or pissing away more money at retail. I can appreciate the shops need to keep the lights on but some are hoping to send their kids to college on you ; like everything, shop around.
