I bought a new coldsteel machette for the bugoutbag and am trying to figure out how to sharpen it easily. Would it be o.k. to use the small grinding/sanding wheel with a dremel tool? One day I will learn the ins and outs of sharpening blades correctly. I take my expensive knives to professionals when they need sharpening and since the machette is inexpensive, i'd just like to do it myself. Thanks
