I recommend the Sentry Solutions Tuf-Cloth and Tuf-Glide lubricant and rust inhibitor. I personally use the Marine Tuf-Cloth for a little more protection on my knives from saltwater and high humidity. For more info, check out www.sentrysolutions.com<br><br>As far as sharpening systems, I use the Spyderco Sharpmaker 204. It's a little more than your requested dollar range (about $60), but well worth the money. It comes with an instructional video and book for step-by-step instruction on how to use the system. For reprofiling the edges, I use a DMT Diafold (fine, extra fine), until I get the diamond triangles for the 204.<br><br>Good Luck.
