how many of you with the paper wheels are confident enough to sharpen knives at a fundraiser? its a good way to have fun and help out a good cause (not to mention get customers). when you set up at one, it wont be long before you have a crowd watching what you are doing and wanting their knives sharpened. i watch out for knives made in pakistan since the soft stainless seems to clog the wheels. most of them wont sharpen up and then you have someone complaining because you didnt get their cheap knife sharp. they tend to have a certain color and finish to the steel which i also look out for just in case there isnt any markings on the blade.
