Does anyone know where I can get a sharpening stone?
Try Alpine knife and clock store. They've got a crazy selection of knives, etc. Other than that, maybe try bed bath and beyond or williams sonoma.

I saw a set at K-Mart on Vets near causeway (its in a case behind the register in sporting goods.). I would also try at Puglia's nearby.
