Ok, price of the knife sharpener is less of a factor. That knifeworks website has some nice specials, and a couple Benchmade field sharpeners at $10. Some place had it, I think Knifeworkds, the Spyderco for $53 so not bad. And since I can use it on scissors and awls (like I am gonna run out and buy an awl, but hey, I do have this belt that ......) could make sense.
Ok, why would I get the Delica over say one of the $25 or so knives at knifeworks here: http://www.knifeworks.com/specialpriceitems.aspx
If the Delica is a bit rich for your blood, look at the Kabar Dozier Folding hunter. It comes in three sizes, all under 35 bucks I think, and its a great knife. I own the large one. Phenomenal.
Please do not get a pull-through "vee" type sharpener like the Benchmade field sharpener. They aren't very good.
