DMT Diamond Sharpeners are fun, especially the ones where you have a milled steel plate that's very flat to which the diamond abrasive is fixed via some nickelplating process. Use one thats "extracoarse" on one side and "fine" (600grit) on the other plus another onsided one with extra fine. Finish with japanese whetstone (synthetic one) and or polishing pashe on a strap of leather. Takes almost no space, can be done at the kitchen table. The equipment costs some, so its probably mostly worth it if you like doing it - sharpening has a meditative quality (wear theowaway gloves)
Yes. These are awesome. They have ones that fold up inside an attached plastic cover (like leatherman) that are great for apartment living, and will sharpen pretty much anything, from filet and paring knives to axes.
