The ability to sharpen knives is a valuable skill. My suggestion would be getting a pos from a thrift shop, and make it sharp enough to shave with. A triple stone set mounted on a triangle is affordable, and is more than enough for the task. You use the synthetic stone to regrind the edge if it's a disaster, follow with the medium Arkansas to get it right. then finish with a hard Arkansas for a nice edge. That'll give you a new skill, self sufficiency, and satisfaction of a job well done. Practice on the junk so you don't mess up your good blades.
