Not happy with the $19.95 blade sharpener from JoAnns. Rather go out and purchace new blades when on sale or have coupons. Did find a plastic jar that the "stone" part of the sharpener set on and that kind of helped a little but still not real impressed. Haven't tried a binder tool. Rather do it by hand because never know for sure what kind of binding will be going on a quilt. Do up a lot of charity quilts for veterans. Love them veterans, let's give our veterans a standing ovation and thank them every chance we get. (sorry, I gets carried away).
